OFweek Instrumentation Network News In recent years, with the government's emphasis on the treatment of air pollution, especially urban haze management, the monitoring and management of subdivided pollutants such as volatile organic compounds (VOCs) has also been frequently put on the agenda. Recently, the Ministry of Environmental Protection reviewed and approved the "13th Five-Year Plan for the Prevention and Control of Volatile Organic Pollutants" to comprehensively strengthen the prevention and control of volatile organic compounds (VOCs), further improve the quality of the ambient air, and fight against the blue sky.
Volatile organic compounds (VOCs) are organic compounds having a saturated vapor pressure of more than 70 Pa at normal temperature and a boiling point of 260 ° C or less at normal pressure, or all organic compounds having a corresponding vapority at a vapor pressure of 10 Pa or more at 20 ° C. At present, there are more than 300 kinds of VOCs, mainly from architectural decoration, organic chemicals, petroleum and petrochemical, packaging and printing, surface coating and other industries, which have great impact on human health and social environment. With the development of China's chemical industry and manufacturing industry, the emission of VOCs has been high. In addition, China has not included VOCs into the scope of conventional pollutant management for a long time. VOCs governance has always been the focus and difficulty of air pollution prevention and control in China. One.
In order to strengthen the governance of VOCs, China has successively issued the “Action Plan for Volatile Organic Compounds Reduction in Key Industries” and “Comprehensive Work Plan for Energy Saving and Emission Reduction in the “13th Five-Year Plan”. During the “Thirteenth Five-Year Plan” period, volatile organic compounds (VOCs) emissions were included in the total control indicators, and VOCs were continuously strengthened throughout the country to monitor emissions. In order to strengthen the implementation of VOCs pollution remediation work, Shaanxi Tongchuan has implemented VOCs treatment reform, consolidation and improvement to ensure stable discharge compliance, and formulated the “Congchuan Iron Handling Treatment” Volatile Organic Pollutants in 2017 for key enterprises such as surface coating, packaging and printing, and furniture manufacturing. Special Action Plan for Remediation; Hebei Tangshan stopped the emission reduction of key industries, and the VOCs process discharges were not up to standard, so as to stop the production of VOCs; Jiangsu Suqian established an online monitoring platform and put it into use, real-time online monitoring of VOCs emissions 24 hours a day. concentration.
