All over VOCs special help inspection in progress! What should companies do?

In recent years, China's air quality has been continuously improving but ozone pollution has become an important factor affecting summer air quality and volatile organic compounds () are important precursors to the formation of ozoneTake Guangdong as an example because of this year's high temperature Guangdong ozone pollution than the same period last year appeared earlier, moreAs of the end of the month, Guangdong province's city pollution days in the city is due to the ozone standard caused by the standardThe Minister of Ecological Environment from the month to the sun led a team to The Protection of ecological environment in Xuzhou, Jiangsu Province, Zhejiang Province, in Zibo, Binzhou and DongyingDuring the investigation, respectively, to Zhejiang Sany Equipment Co., LtdXuzhou Heavy Machinery Co., Ltdand furniture manufacturing enterprise cluster Shandong Qilu Petrochemical, Binzhou Boxing color plate enterprise cluster and Dongying Guangrao Petrochemical Enterprise Cluster to learn more about enterprise governanceHe pointed out that the current ozone generation in China is mainly a control-type benchmark enterprises in governance to do a good role model model high standards, strict requirements to keep a close eye on each link do not relax and effectively strengthen collection and treatment efforts to achieve source substitution, process closed, efficient disposalFrom the beginning of the month will focus on Beijing-Tianjin-Hebei and surrounding areas, the Wei Plain, The Suluyu junction area, the Yangtze River Delta region, the Yangtze River midstream city group and other areas in accordance with the problem precision, time accuracy, location accuracy, accurate object, precision of measures on volatile organic matter emissions, ozone pollution prevention and control pressure, environmental air quality improvement target progress in the city to carry out summer ozone pollution prevention and control guidance and help the relevant government, enterprises to implement the implementation of volatile organic emission reduction tasksOn the implementation of the relevant documents on governance, "Annual Volatile OrganicS Governance Plan (Draft for Comments)" issued on the month "on the request for "annual volatile organic compound governance plan (draft for comments)" letter" which clearly from the beginning of the month in accordance with the "double random, one open" model to carry out special law enforcement actions for enterprises that can not stabilize the emission standards, do not meet the requirements of non-organizational control to punish according to the law"On the situation in the epidemic prevention and control of the normal premise of active service implementation of the "six insurance" task resolutely win to fight the battle against pollution, " the Ministry of Ecological Environment issued on the month "on the epidemic prevention and control of the normal premise of active service to implement the "six insurance" task resolutely win a good battle against pollution prevention and control opinions (ring hall (the department) no) for the control clear many requirements pointed out: Strengthen summer and autumn (month-month) volatile organic matter (month) governance in heavily polluted areas to promote the construction of appropriate and efficient governance facilities to deal with inefficient governance facilities to carry out upgradingPriority should be given to the production and use of low-source auxiliary material souratingEnterprises that do not have low primary source substitution and do not adopt efficient governance facilities are encouraged to adopt wrong peak emission reduction measures in the summer and autumn, highlight the heavy pollution of the weather responseIn particular, it is predicted that the implementation of emergency emission reduction pilot projects for major emission processes when large-scale pollution processes may occur is implemented into
