Work plan for the prevention and control of VOC pollution in the 13th five year plan

Volatile organic compounds (VOCs) refer to organic compounds involved in atmospheric photochemical reactions, including non methane hydrocarbons (alkanes, olefins, alkynes, aromatic hydrocarbons, etc.), oxygenated organics (aldehydes, ketones, alcohols, ethers, etc.), chlorinated organics, nitrogen-containing organics, sulfur-containing organics, etc. they are important precursors for the formation of ozone (O3) and fine particulate matter (PM2.5) pollution. This plan is formulated to comprehensively strengthen the prevention and control of VOCs Pollution, improve the scientificity, pertinence and effectiveness of management, and promote the continuous improvement of ambient air quality.

1、 Fully understand the importance of Comprehensively Strengthening the prevention and control of VOCs Pollution

At present, China takes PM2 The situation of air compound pollution with 5 and O3 as characteristic pollutants is still severe. Since the implementation of the action plan for the prevention and control of air pollution, the national ambient air quality has been continuously improved, and PM2 in key areas such as Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta 5. The concentration decreased by more than 30%, and the concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2) and inhalable particulate matter (PM10) also decreased significantly, but PM2 The concentration of 5 is still at a high level, and Beijing Tianjin Hebei and its surrounding areas far exceed the national ambient air quality class II standard (hereinafter referred to as the national class II standard); At the same time, O3 concentration in key areas shows an upward trend, especially in summer and autumn, which has become the primary pollutant in some cities. From 2013 to 2016, the O3 concentration (90th percentile of daily maximum 8-hour average concentration) in the first batch of 74 cities implementing the new ambient air quality standards increased by 10.8%; In 2016, the concentration of O3 in 59 of 338 prefecture level and above cities exceeded the national secondary standard; The O3 concentration in Beijing Tianjin Hebei and Yangtze River Delta exceeds or approaches the national secondary standard. From PM2 In terms of precursor control of 5 and O3, significant progress has been made in the control of SO2, nitrogen oxides (NOx) and smoke and dust in China in recent years, but the emission of VOCs still shows an increasing trend, with an increasingly prominent impact on the atmospheric environment. VOCs emission will also lead to the enhancement of atmospheric oxidation, and some VOCs will produce odor. In order to further improve the ambient air quality and fight for the blue sky, it is urgent to comprehensively strengthen the prevention and control of VOCs Pollution.

2、 General requirements and objectives

3. Implement peak shifting production in industrial enterprises. All localities should strengthen the seasonal regulation and control of the production of industrial enterprises, give full consideration to the utilization rate of industrial capacity, production process characteristics and pollution emission, and focus on O3 pollution and PM2 pollution in summer, autumn and winter respectively 5. The pollution research puts forward the requirements for peak shifting production in the industry, guides enterprises to reasonably arrange the production period and reduce the impact on ambient air quality. Enterprises shall formulate peak shifting production plans and implement them in the enterprise's pollutant discharge permit and emergency plan in accordance with the law and regulations. In areas with serious O3 pollution, we can focus on the industries producing olefins, alkynes and aromatics in summer and autumn to study and formulate production regulation plans. PM2. 5 in areas with serious pollution, production regulation measures can be implemented for industries producing aromatic hydrocarbons in winter. Beijing Tianjin Hebei air pollution transmission channel cities implement staggered peak production in the heating season for the VOCs emission process of pharmaceutical enterprises involved in the production of APIs and the VOCs emission process of pesticide enterprises using organic solvents in the production process.

（2） We will accelerate the prevention and control of VOCs Pollution from industrial sources.
