摘要：VOCs pollution has a significant impact on the atmospheric environment. Volatile organic compounds (VOCs) are important precursors for the formation of fine particulate matter (PM2.5) and ozone (O3), and have become one of the main pollutants of atmospheric pollution. In order to further improve the ambient air quality, it is urgent to comprehensively strengthen the comprehensive management of VOCs in key industries. Based on the characteristics of pollution production in VOCs-related industries, focusing on source control, unorganized collection, and end-of-line governance, develop a multi-factor and multi-indicator performance evaluation system, and use field surveys-field monitoring-site scoring-suggestions-corporate rectification Performance evaluation of key emission enterprises. On-site assessment was conducted on 380 companies in key industries related to VOCs, such as pharmaceuticals, pesticides, and chemicals, and 2,396 suggestions on environmental protection related rectification were put forward to guide enterprises to upgrade and achieve precise and scientific pollution control. After the improvement of deep governance, the calculation of emission reduction performance of VOCs-related companies shows that the annual emission reduction of VOCs in the pharmaceutical industry is 722.113 t·a−1, the annual emission reduction of pesticide industry is 842.555 t·a−1, and the emission reduction of chemical industry is 1498.835 t·a−1. The annual emission reduction is 3227.63 t·a−1, and the source control emission reduction is 6929.862 t·a−1. The total reduction of VOCs in 2019 is 13220.994 t·a−1.
