Heavy pollution weather in autumn and winter is approaching again, and emergency measures are launched in many places.

heavy pollution weather in autumn and winter is prone to occur. Recently, many provinces have launched comprehensive air pollution control actions in autumn and winter. On the 26th, the Ministry of ecological environment held a mobilization meeting for the comprehensive treatment of air pollution in key areas in autumn and winter. The relevant person in charge of the Ministry of ecological environment stressed that Beijing Tianjin Hebei and its surrounding areas, Chang Sanjiao and Fen Wei plain are the key areas of air pollution prevention and control, and also the main battlefield of the action

it is worth mentioning that since October 20, a pollution process has occurred in Beijing Tianjin Hebei and its surrounding areas. For this heavily polluted weather process, all regions actively respond in advance. Eight cities in Hebei Province, including Shijiazhuang, Tangshan and Langfang, issued orange warnings for heavy pollution shear test weather. Henan Province has launched emergency control and verification of heavily polluted weather. Level III emergency response measures for heavily polluted weather in various cities include the suspension and restriction of industrial enterprises, the restriction of different types of motor vehicles, the suspension of earthwork operations and the strengthening of road cleaning

not only that, according to the Ministry of ecological environment, Shanxi Province recently carried out the comprehensive treatment of air pollution in autumn and winter, requiring 11 cities in the province to fully complete the 2018 air quality improvement goal (with emphasis on the PM2.5 goal). Previously, Hebei Environmental Emergency and heavy pollution weather warning center said that at this stage, the energy structure, industrial structure and transportation structure of Hebei Province, the number of power lithium battery enterprises in China has been reduced from 84 to 40, which is unreasonable. It is still necessary to completely eliminate heavy pollution weather in autumn and winter, but it is necessary to address both the symptoms and root causes when using it, and further promote the comprehensive treatment of air pollution in autumn and winter

in addition to the above-mentioned provinces, Henan, Jiangsu and other places have also launched comprehensive action plans for air pollution control in autumn and winter. Among them, Jiangsu Province requires that peak shifting production be implemented in key industries such as steel, building materials and coking from November 2018 to February 2019. Henan Province has set up nine pollution weather emergency management and control verification teams to verify and supervise the emergency management and control launched in Zhengzhou, Kaifeng, Pingdingshan and other key areas since October 21

relevant experts from the National Joint Center for air pollution prevention and control believe that heavy pollution weather is easy to occur in autumn and winter, on the one hand, due to the increase in the emission of pollutants with a certain odor, on the other hand, due to the change of meteorological conditions. Especially after entering the heating season, the emission of pollutants increases, which is very easy to produce heavily polluted weather

the expert pointed out that for the prevention and control of heavily polluted weather in autumn and winter, we should further optimize the industrial structure and concentrate on the rectification of "scattered pollution" enterprises; In addition, optimize the energy structure, promote the elimination and transformation of small coal-fired boilers, and focus on the development of clean energy; At the same time, optimize the transportation structure and carry out special rectification of excessive emissions from diesel trucks
