Second, promote the idea

(3) Vigorously promote source substitution. By using water-based, powder, high solids, solvent-free, radiation-curing coatings with low VOCs content, water-based, radiation-curing, plant-based inks with low VOCs content, water-based, hot-melt, solvent-free, radiation curing, modification And biodegradable adhesives with low VOCs content, as well as cleaning agents with low VOCs content and low reactivity, replace solvent-based coatings, inks, adhesives, cleaning agents, etc., and reduce VOCs production from the source. Industrial coatings, packaging and printing industries should increase source substitution efforts; the chemical industry should promote the use of low (no) VOCs content and low reactivity raw and auxiliary materials to accelerate the green substitution of aromatic hydrocarbons and halogen-containing organic compounds. Enterprises should vigorously promote the use of low VOCs content wood coatings, vehicle coatings, machinery equipment coatings, container coatings and protective coatings for buildings and structures, etc., in industries with mature technologies, promote the use of low VOCs content inks and adhesives, and encourage accelerated low VOCs content coatings , Inks, adhesives and other research and development and production.

Strengthen policy guidance. Enterprises are encouraged to adopt coatings, inks, adhesives, etc. that comply with national regulations for low-VOC content products, where the discharge concentration is stable and the discharge rate and discharge performance meet relevant national regulations, and the corresponding production processes may not require the construction of end-of-life treatment facilities. For processes where the VOCs content (mass ratio) of the raw and auxiliary materials used is less than 10%, no fugitive emissions collection measures are required.

(4) Comprehensively strengthen the control of fugitive emissions. Focus on five categories of storage, transfer and transportation of VOCs-containing materials (including VOCs-containing raw and auxiliary materials, VOCs-containing products, VOCs-containing waste materials, and organic polymer materials, etc.), leakage of equipment and pipeline components, open liquid surface dissipation, and process processes Emissions sources are controlled, and measures to reduce the fugitive emissions of VOCs are taken through measures such as equipment and site containment, process improvements, and effective collection of exhaust gas.

Strengthen the closed management of equipment and places. VOCs-containing materials should be stored in closed containers, packaging bags , highly efficient sealed storage tanks, closed storages, silos, etc. VOCs containing materials should be transferred and transported in closed pipes or closed containers, tankers, etc. The collection, transportation, storage and treatment of high VOCs wastewater (the detection concentration of VOCs at 100 mm above the liquid level of the wastewater exceeds 200 ppm, of which the key area is more than 100 ppm, based on carbon) should be sealed and sealed. During the production and use of VOCs-containing materials, effective collection measures should be taken or operated in confined spaces.

Promote the use of advanced production processes. Through the use of fully enclosed, continuous, automated and other production technologies, as well as efficient processes and equipment, it reduces the fugitive emissions of the process. Volatile organic liquids are preferably loaded at the bottom. The petrochemical and chemical industries focus on promoting the use of low (no) leakage pumps, compressors, filters, centrifuges, drying equipment, etc., and promote the use of online oil blending technology and closed circulating water cooling systems. The industrial coating industry focuses on promoting the use of compact coating processes, promoting the use of roller coating, electrostatic spraying, high-pressure airless spraying, air-assisted airless spraying, thermal spraying and other coating technologies, and encouraging enterprises to use automated and intelligent spraying equipment instead of manual labor.

Improve exhaust gas collection rate. Following the principle of "receivable and exhausted collection, quality collection", scientifically design the exhaust gas collection system to transform unorganized emissions into organized emissions for control. Where a fully-closed air hood or enclosed space is used, unless there are special requirements in the industry, a slight negative pressure state should be maintained, and the ventilation volume should be reasonably set in accordance with relevant specifications. Where a local air hood is used, the unorganized emission position of VOCs farthest from the opening surface of the air hood shall be controlled at a speed of not less than 0.3 m / s. If required by the industry, it shall be implemented in accordance with relevant regulations.

Strengthen leakage control of equipment and pipeline components. For equipment and pipeline components containing gaseous and liquid VOCs in enterprises, if the number of sealing points is 2,000 or more, LDAR work shall be carried out according to requirements. Petrochemical companies will implement the industry's emission standards.

(5) Promote the construction of suitable and efficient pollution control facilities. Enterprises constructing new pollution control facilities or retrofitting existing pollution control facilities should reasonably choose treatment technologies based on the concentration, composition, air volume, temperature, humidity, pressure, and production conditions of the exhaust gas. Encourage enterprises to adopt a combination of multiple technologies to improve the efficiency of VOCs governance. For low-concentration, high-volume exhaust gas, concentration techniques such as zeolite runner adsorption, activated carbon adsorption, and wind-reduction and enrichment should be adopted to improve the concentration of VOCs after purification. For high-concentration exhaust gas, priority is given to solvent recovery. Catalytic combustion and other technologies. The recovery of oil and gas (solvent) should adopt technologies such as condensation + adsorption, adsorption + absorption, membrane separation + adsorption. Low-temperature plasma, photocatalysis, and photo-oxidation technologies are mainly applicable to the treatment of malodor and odor; biological methods are mainly applicable to the treatment of low-concentration VOCs waste gas and malodor. Water-insoluble VOCs exhaust gas is prohibited from spraying or absorbing with water or aqueous solution. Where disposable activated carbon adsorption technology is used, the activated carbon should be replaced regularly, and the waste activated carbon should be regenerated or disposed of. Conditional industrial parks and industrial clusters, etc., promote centralized spraying, concentrated solvent recovery, and activated carbon centralized regeneration, etc., to strengthen resource sharing and improve the efficiency of VOCs management.

Standardize engineering design. Adsorption treatment process shall meet the requirements of "Technical Specifications for Adsorption Industrial Organic Waste Gas Treatment Engineering".

Where other treatment processes such as regenerative combustion are used, they shall be designed in accordance with the relevant technical specifications.

Implement dual control of emission concentration and removal efficiency of key emission sources. The initial exhaust rate of VOCs collected by the workshop or production facility is 3 kg / hour or more. Control should be strengthened. In addition to ensuring the stable emission concentration, the removal efficiency control should be implemented, and the removal efficiency should not be less than 80%. Except that the raw and auxiliary materials meet the national regulations on products with low VOCs content, those with industry emission standards shall be implemented in accordance with their relevant regulations.

(6) In-depth implementation of fine management and control. Each city (prefecture) determines the key industries and key pollutants controlled by VOCs in the region according to the local environmental air quality improvement needs, based on the analysis of O3 and PM2.5 sources, combined with the industry's pollution emission characteristics and the photochemical reactivity of VOCs substances, taking into account the malodor pollution And effective toxic and hazardous substances control, and put forward effective management and control programs to improve the accuracy, pertinence and effectiveness of VOCs management. For VOCs substances that are subject to control, refer to Annex 2 (VOCs substances that are subject to control).

Implement the "one factory, one policy" system. All localities should strengthen guidance for enterprises, and organize experts to provide professional technical support for enterprises with large local pollutant emissions, strictly control, guide enterprises to prepare practical pollution treatment programs, and clarify the replacement of raw and auxiliary materials, process improvements, The entire process of emission reduction requirements such as unorganized emission control, exhaust gas collection, and pollution control facilities construction, measures investment costs and emission reduction benefits, and provides technical services for enterprises to effectively implement comprehensive treatment of VOCs. Local governments are encouraged to implement mandatory cleaner production audits in key industries.

Strengthen enterprise operation management. Enterprises should systematically sort out the main links and procedures of VOCs emissions, including start-up and shutdown, inspection and maintenance operations, etc., formulate specific operating procedures, and implement them to specific responsible persons. Improve the internal assessment system. Strengthen personnel capacity training and technical exchanges. Establish a management ledger to record the key parameters of the enterprise's production and pollution control facilities, as shown in Annex 3 (VOCs governance ledger record requirements). Online monitoring parameters must be accessed in real time. Relevant ledger records are kept for at least three years.

III. Key tasks

(7) Comprehensive management of VOCs in petrochemical industry. Comprehensively increase the control of VOCs in petroleum refining and organic chemicals, synthetic resins, synthetic fibers, synthetic rubber and other industries. Emphasis will be placed on strengthening the treatment of VOCs in leaking points such as sealing points, waste water and circulating water systems, storage tanks, organic liquid loading and unloading, and process waste gas to ensure stable discharges.

Deepen LDAR work. In strict accordance with the "Guidelines for the Leak Detection and Repair Work of Petrochemical Enterprises", a ledger is established to carry out leak detection, repair, quality control, and record management. Strengthen the testing of standby pumps, in-use pumps, regulating valves, stirrers, open pipelines, etc., and strengthen quality control; incorporate VOCs treatment facilities and sealed points of storage tanks into the inspection plan. With reference to the "Supervisory Standards for Volatile Organic Compounds Emission Control" related to the monitoring requirements for leakage control of VOCs of equipment and pipeline components, strengthen the supervision of leaks at sealed points in petrochemical companies. Encourage key enterprises in Harbin and Daqing to implement the bagging method for sealing points with large leakage, and use infrared method for unreachable sealing points.

Strengthen the collection and treatment of VOCs in wastewater and circulating water systems. Intensify the transformation of wastewater collection and transportation systems. Existing key enterprises in Harbin and Daqing have gradually adopted open pipelines to replace open drains, trenches, canals, and wells. Comprehensively strengthen the collection and treatment of high-concentration VOCs waste gas in the wastewater system. Collecting wells (pools), regulating ponds, oil traps, air floatation ponds, and concentration ponds should adopt closed processes or closed collection measures, and support the construction of efficient pollution treatment facilities such as combustion. Biochemical tanks, aeration tanks and other low-concentration VOCs waste gas should be collected in a closed manner, and deodorization and other treatment should be implemented to ensure compliance with standards. Strengthen the monitoring of circulating water. The key petrochemical companies in Harbin and Daqing strive to carry out the monitoring of total organic carbon (TOC) or purgeable organic carbon (POC) for the import and export of circulating water towers and heat exchange equipment containing VOCs every six months, and export. If the concentration is greater than 10% of the imported concentration, trace the source leak point and repair it in time.

Strengthen the management of storage tanks and organic liquid handling VOCs. Intensify the treatment of intermediate storage tanks, etc. If the true vapor pressure is greater than or equal to 5.2 kilopascals (kPa), effective control measures must be taken in strict accordance with relevant regulations. The existing key enterprises in Harbin and Daqing are encouraged to take control measures for organic liquids with a true vapor pressure of 2.8 kPa or more. To further strengthen the management of VOCs during the loading and unloading of volatile organic liquids, cities (regions) with conditions can promote the bottom loading method of tank trucks, promote the use of oil and gas recovery systems for ship loading and unloading, and conduct pilot loading of trains. For storage tanks and organic liquid loading and unloading, end-of-line treatment measures shall be taken to ensure stable operation.

Deepen the treatment of process VOCs. Effectively implement the treatment of catalyst regeneration exhaust gas and oxidation tail gas VOCs, and strengthen the treatment of tail gas VOCs in acid water tanks, delayed coking, synthetic rubber, synthetic resin, synthetic fibers and other processes. Promote fully enclosed production processes and increase collection of fugitive emissions.

We will focus on increasing the level of containment of major VOCs-related emissions processes, strengthening the collection of fugitive emissions, and strengthening the storage and handling of VOCs-containing materials. Wastewater storage and aeration tanks and their previous wastewater treatment facilities shall be covered and closed as required, and waste gas collection and treatment shall be implemented. If there are 2000 or more sealing points, LDAR work shall be carried out to encourage the modern coal chemical industry to implement LDAR in full compliance with the requirements of the petrochemical industry.

Actively promote the use of raw and auxiliary materials with low VOCs content or low reactivity to accelerate process improvements and product upgrades. The pharmaceutical and pesticide industries promote the use of non-halogenated hydrocarbons and non-aromatic hydrocarbon solvents, and encourage the production of water-based pesticide formulations. The rubber products industry promotes the use of new coupling agents and adhesives, and the use of paraffin oil instead of ordinary aromatic oil, coal tar and other additives. Optimize production technology, pesticide industry promotes water phase method, bio-enzymatic synthesis and other technologies; pharmaceutical industry promotes bio-enzymatic synthesis technology; rubber products industry promotes tandem mixing, atmospheric continuous desulfurization process.

Speed up the closed transformation of production equipment. Adopt sealing measures to improve the level of technology and equipment for the processes of incoming and outgoing materials, material transportation, mixing, solid-liquid separation, drying, and filling. Speed up the elimination of open and open-flow facilities. Conditional cities (prefectures) can implement the state's requirements for key areas.

Strictly control VOCs emissions during storage and handling. Encourage the use of pressure tanks, floating roof tanks, etc. instead of fixed roof tanks. Organic liquids with a true vapor pressure greater than or equal to 27.6 kPa, if stored in a fixed top tank, shall adopt a gas phase equilibrium system or a collection and purification treatment in accordance with relevant regulations.

Carry out separate collection and treatment of exhaust gas. Recovery technologies such as condensation and adsorption regeneration are preferred; for those that are difficult to recover, efficient treatment technologies such as combustion, adsorption concentration, and combustion should be used. Water-soluble, acid-base VOCs waste gas should be treated with multi-stage chemical absorption. Deodorizing waste gas should be further strengthened.

Strengthen the control of exhaust emissions under abnormal working conditions. The process of returning materials, purging and cleaning should strengthen the recovery of VOCs-containing materials, and the VOCs waste gas generated should be collected and treated more vigorously. Volatile non-conforming products generated during the start-up phase should be collected in devices such as intermediate storage tanks. Qualified chemical companies can formulate operating procedures for controlling VOCs under abnormal operating conditions such as start-up, shutdown, inspection and maintenance.

(9) Comprehensive treatment of industrial coating VOCs. Strengthen the management of VOCs in the automobile, furniture, container, electronic products, construction machinery and other industries.

Strengthen source control, and accelerate the use of powder, water-based, high solids, radiation curing and other coatings with low VOCs content to replace solvent-based coatings. Steel container manufacturing vigorously promotes the use of water-based coatings in the interior, exterior, and wooden floor coating processes, and accelerates the use of water-based coatings for special containers on the premise of ensuring the anti-corrosion function. Wooden furniture manufacturing vigorously promotes the use of water-based, radiation curing, powder and other coatings and water-based adhesives; metal furniture manufacturing vigorously promotes the use of powder coatings; software furniture manufacturing vigorously promotes the use of water-based adhesives. Construction machinery manufacturing vigorously promotes the use of water-based, powder and high-solid coatings. Electronic product manufacturing promotes the use of powder, water-based, radiation-curing coatings.

Accelerate the promotion of compact coating processes, advanced coating technologies and equipment. Automobile manufacturing and vehicle production have promoted the use of compact processes such as "three coatings and one baking", "two coatings and one baking", or intermediate-free coating, electrostatic spraying technology, and automated spraying equipment. Automotive metal parts companies encourage the use of powder electrostatic spraying technology. Roller coating process is used for steel plate processing in one sand blasting process of container manufacturing. Wooden furniture promotes the use of highly efficient reciprocating spray boxes, robots and electrostatic spray technology. For panel furniture, spraying technology is used to promote the use of powder electrostatic spraying technology; for solvent-based and radiation-curing coatings, roller coating and shower coating are popularized. Construction machinery manufacturing should increase the indoor coating ratio, and encourage the use of automatic spraying, electrostatic spraying and other technologies. Electronic product manufacturing promotes the use of electrostatic spraying and other technologies.

Effectively control fugitive emissions. Coatings, thinners, cleaning agents and other raw and auxiliary materials should be stored tightly. The process of deployment, use, and recovery should be carried out in a closed device or in a closed space, and transported in closed pipes or closed containers. Except for large workpieces, open-type spraying and air-drying (air-drying) operations are prohibited. In addition to process restrictions, centralized deployment is implemented in principle. VOCs emission processes such as deployment, spraying and drying should be equipped with an effective exhaust gas collection system.

Promote the construction of suitable and efficient pollution control facilities. The spraying exhaust gas should be provided with an efficient paint mist treatment device. Spraying, drying (air) dry exhaust gas should adopt the adsorption concentration + combustion treatment method, and small air volume can adopt one-time activated carbon adsorption and other processes. The mixed and flowable exhaust gas can be treated with spraying and air drying (air) drying exhaust gas. For production lines using solvent-based coatings, the drying exhaust gas should be treated separately by a combustion method, and those with conditions can use a recovery type thermal combustion device.

(10) Comprehensive management of VOCs in the packaging and printing industry. Focus on promoting the management of VOCs such as plastic flexible packaging printing and printed iron cans, actively promote the use of low (no) VOCs content of raw and auxiliary materials and environmentally friendly technologies to replace, comprehensively strengthen fugitive emission control, and build efficient terminal purification facilities. Conditional cities (prefectures) can gradually carry out the management of VOCs for publication printing.

Can manufacturers have promoted the use of water-based inks and coatings. Encourage packaging and printing enterprises to implement technological transformations such as offset printing and flexo printing.

Strengthening fugitive emissions control. Strengthen the control of VOCs fugitive emission during the storage, deployment, transportation, and use of VOCs-containing materials such as inks, thinners, adhesives, coating solutions, and cleaning agents. VOCs containing materials should be kept closed during storage and transportation. The deployment should be carried out in a closed device or space and effectively collected. The non-ready state should be sealed with a cover. Coating, printing, laminating, laminating, glazing, cleaning and other materials containing VOCs should be used in closed equipment or operated in a confined space; if it cannot be sealed, local gas collection measures should be taken and the exhaust gas is discharged to the VOCs exhaust gas collection system. Gravure and flexographic printing presses should use closed doctor blades, or reduce the ink tank's unstructured dissipation by installing cover plates and changing the shape of ink tank openings. Conditional printing companies can carry out negative pressure reconstruction or local wind reconstruction for VOCs emission workshops.

Improve end governance. For packaging and printing companies, VOCs emission processes such as printing and dry compounding should adopt adsorption and concentration + condensation recovery, adsorption and concentration + combustion, wind reduction and enrichment + combustion and other efficient treatment technologies.

(11) Comprehensive management of VOCs for oil storage, transportation and sales. Increase the control of VOCs emissions from gasoline (including ethanol gasoline), naphtha, kerosene (including aviation kerosene), and crude oil, and focus on promoting the recovery and management of oil and gas at gas stations, tank trucks, and oil depots. Conditional cities (prefectures) can try to promote oil and gas recovery and treatment of oil tankers.

Deepen oil and gas recovery at gas stations. For buried oil tanks, electronic liquid level gauges are used for closed gas measurement of gasoline. Standardize the operation of oil and gas recovery facilities, and strengthen the inspection of gas-liquid ratio, system tightness, and pipeline fluid resistance of the refueling gun by yourself or by a third party to ensure the normal operation of the oil and gas recovery system. Accelerate the work of gas station oil storage and gas recovery and management. Gas storage tanks in gas stations with annual gasoline sales of more than 5,000 tons in Harbin and Daqing should be installed with oil and gas recovery systems and online monitoring equipment, and networked with the ecological environment department.

Promote oil and gas recovery and management in oil storage. Gasoline, aviation kerosene, crude oil, and naphtha with a real vapor pressure of less than 76.6 kPa should be stored in floating roof tanks. Among them, horizontal oil storage tanks can be used for oil products with a volume of 100 cubic meters or less. Naphtha with a true vapor pressure of 76.6 kPa or more should be stored in a low-pressure tank, pressure tank, or other equivalent measures. Accelerate the collection and processing of oil and gas discharged during the process of receiving and dispatching oil products. Strengthen the leak detection of the interface of the oil and gas recovery system of oil storage tanks, increase the frequency of detection, reduce oil and gas leakage, and ensure the normal operation of the oil and gas recovery and processing device during the oil loading and unloading process.

Promote the installation of automatic monitoring facilities for oil and gas recovery in oil storages.

(12) Comprehensive management of VOCs in industrial parks and industrial clusters. All cities (regions) should increase the comprehensive improvement of VOCs-emitting industrial parks and industrial clusters, strengthen resource sharing, implement centralized governance, carry out park monitoring and evaluation, and establish environmental information sharing platforms.

For industrial parks and industrial clusters where coating companies are concentrated, such as furniture, machinery manufacturing, electronic products, and automobile maintenance, encourage the construction of centralized coating centers and equip them with efficient exhaust gas treatment facilities instead of scattered coating processes. For petrochemical and chemical industrial parks and industrial clusters, we will implement unified supervision of leak detection and encourage the establishment of park LDAR information management platforms. For industrial parks and industrial clusters that use a large amount of organic solvents, such as packaging and printing, fabric finishing, synthetic rubber and its products, etc., promote the construction of a centralized organic solvent recovery and disposal center to improve the recycling rate of organic solvents. For industrial parks and industrial clusters with a large amount of activated carbon use, encourage local overall planning, build regional activated carbon centralized regeneration bases, establish a management model for activated carbon dispersed use, unified recovery, and centralized regeneration, and effectively solve the problem of untimely replacement and desorption of activated carbon. 2. It is difficult to supervise, and the pollutants such as desorbed VOCs should be properly disposed of.

Strengthen unified management of industrial parks and industrial clusters. Set industry benchmarks, formulate comprehensive improvement programs, and guide the overall upgrade of industrial parks and industrial clusters. In petrochemical and chemical industrial parks and industrial clusters, it is necessary to establish and improve archive management systems, clarify the source spectrum of corporate VOCs, identify characteristic pollutants, state the construction of corporate exhaust gas collection and treatment facilities, emergency plans for severely polluted weather, and penalties for corporate violations information. Encourage integrated services such as monitoring, investigation, and construction and operation of environmental protection facilities for parks and industrial clusters.

Improve the monitoring and monitoring capabilities of industrial parks and industrial clusters. Speed up the monitoring of ambient air quality VOCs in key industrial parks and industrial clusters. Petrochemical and chemical industrial parks should establish a monitoring, early warning and monitoring system, and if available, carry out navigation monitoring, grid monitoring, and traceability analysis. Industrial parks and industrial clusters involving malodor pollution shall promote the implementation of malodor electronic nose monitoring and early warning.

Fourth, safeguard measures

(13) Strengthen organizational leadership. Each city (prefecture) should follow the overall deployment to win the Blue Sky Defense War and further promote the comprehensive management of VOCs in key industries. Eco-environment departments should strengthen coordination with relevant departments and industry associations to form a joint effort; combine the second national pollution source survey and the compilation of pollution source emission inventories to establish key local VOCs governance industries and establish key pollution source management accounts; organize monitoring, Enforcement of law enforcement and scientific research, strengthen supervision and assistance, and carry out special governance actions. For those who do not advance well, work lags behind, and governance is not in place, supervision and accountability should be strengthened.

(14) Strengthen monitoring and surveillance. The petrochemical, coking, API, pesticide, automobile manufacturing, tanning, textile printing and dyeing and other industries that have been provided for the discharge permit management shall carry out self-monitoring in strict accordance with relevant regulations.

Key sources of VOCs emissions from petrochemicals, chemicals, packaging and printing, and industrial coatings are included in the list of key pollutant discharge units. Automatic monitoring facilities are installed at the main sewage outlets, and they are networked with the eco-environment department and will be basically completed by the end of 2020. Encourage qualified cities (prefectures) to install outstanding video surveillance facilities in major emission processes for enterprises with outstanding fugitive emissions. Encourage enterprises to equip with portable VOCs monitoring instruments to keep abreast of pollution discharge status. Qualified enterprises should automatically and continuously record the main parameters of environmental protection facilities operation and related production processes through distributed control systems (DCS). Data such as automatic monitoring and DCS monitoring should be stored for at least one year, and video monitoring data should be stored for at least three months.

Strengthen the quality control of monitoring data. Enterprise self-monitoring should be carried out under normal production conditions. For pollution sources that emit intermittent emissions or have large fluctuations in emissions, the monitoring should cover periods of high emission intensity. The operation and maintenance of automatic monitoring facilities were strengthened, and the data transmission efficiency reached 90%. Under normal operating conditions, as well as abnormal production conditions such as limited production, shutdown, and maintenance, enterprises should ensure that the automatic monitoring facilities operate normally and transmit data on the Internet. Each city (prefecture) shall timely verify and investigate and handle abnormal situations such as missing data and long-term offline. Strengthen the supervision and management of ecological environment monitoring institutions, and publish information about violations of laws and regulations to the public through websites such as "Credit China" for monitoring institutions and personnel who have serious mistrust.

(15) Strengthen supervision and enforcement. Municipalities (prefectures) must strengthen the supervision and enforcement of VOCs emissions, severely crack down on illegal emissions, and form an effective deterrent effect. For enterprises that discharge sewage without a permit, fail to discharge in accordance with a certificate, fail to meet the standards for stable discharge, and fail to meet the requirements of measures and controls, comprehensively use daily means of daily fines, seal-up and seizure, limit production and stop production. Social openness. Seriously investigate and deal with serious illegal acts such as fraud and unauthorised shutdown of environmental protection facilities, and investigate and prosecute related personnel according to law. Rectify and standardize the market order of environmental protection services, and severely crack down on irregular operations in the construction and maintenance of VOCs governance facilities.

Take multiple measures to deal with the chaos of low prices. Increase joint disciplinary efforts, include environmental protection companies with poor construction quality and environmental management facilities with low levels of operation and management, and operation and maintenance organizations that have been fraudulently included in the list of joint disciplinary targets for dishonesty, included in the national credit information sharing platform, and adopted "Credit China" Websites such as the "National Enterprise Credit Information Disclosure System" were announced to the public.

Carry out special law enforcement actions in key industries, focusing on the inspection of unorganized emissions of VOCs, exhaust gas collection, and operation of pollution control facilities. For the main points of inspection, see Annex 4 (Vocs governance checkpoints for industrial enterprises) and Annex 5 (VOCs governance of oil storage, transportation, and sales). Check points). Cities and regions are encouraged to monitor the comprehensive control effect of enterprises by monitoring the concentration of fugitive emissions in the plant area in accordance with the requirements of Appendix A of the Volatile Organic Compounds Emission Control Standard.

Strengthen technical training and law enforcement capacity building. Develop a training plan for law enforcement personnel, focusing on the regulations and standards system for VOCs management, pollution prevention policies, and comprehensive control tasks, key emission links in key industries, emission characteristics, requirements for control measures for unorganized emissions, waste gas collection and treatment technologies, monitoring and technical specifications, On-site law enforcement inspection points, etc., carry out systematic training. In the large-scale training of environmental law enforcement, VOCs law enforcement inspection is an important content of the competition, which effectively promotes the improvement of the actual combat capability of VOCs law enforcement. Improve the level of law enforcement equipment, equipped with portable VOCs rapid detector, VOCs leak detector, breeze anemometer, oil and gas recovery three detectors, etc.

(16) Full implementation of sewage permits. Accelerate the issuance of sewage discharge permits for furniture and other industries in accordance with the requirements of the classified management directory for discharge permits for fixed pollution sources. For the VOCs-related industries that have been issued, strengthen the enforcement and supervision of pollution permits, and ensure that the polluting entities implement the responsibilities of environmental management entities that are licensed to discharge pollutants and discharge pollutants according to certificates. Regularly announce the list of non-certified pollutant discharge units.

(17) Implement differentiated management. Comprehensively consider the company's production technology, the use of raw and auxiliary materials, the level of fugitive emission control, and the operation effect of pollution control facilities, etc., to set industry benchmarks and guide the industrial transformation and upgrading. Provide policy support to benchmarking enterprises in response to severely polluted weather, environmental law enforcement inspections, government green procurement, and corporate credit financing. We will strengthen joint punishment for enterprises with simple pollution control facilities and poor organization and control of emissions.

Strengthening response to severely polluted weather. All localities should comprehensively include VOCs-related enterprises in the emergency pollution reduction list for severely polluted weather to achieve full coverage. For the main VOCs emission procedures, take effective emergency emission reduction measures to implement specific production lines and equipment. Implement differentiated emergency emission reduction management based on pollution emission performance levels. For the use of raw and auxiliary materials such as organic solvents, the end treatment only adopts low-temperature plasma, photocatalysis, photo-oxidation, one-time activated carbon adsorption and other open-ended operations. Cities and regions are encouraged to implement seasonally differentiated VOCs management and control measures in accordance with management requirements. In the season when O3 pollution is heavy, enterprises with large emissions of aromatic hydrocarbons, olefins, aldehydes, etc., are required to put forward further control requirements.
