On June 6, according to the Chengdu Environmental Protection Bureau, the Chengdu leading group office for air pollution prevention and control recently issued the 2017 Chengdu ozone pollution prevention and control action plan, which focuses on the prevention and control of ozone pollution, and strives to reduce the number of days of ozone pollution in the central urban area by about 7 days year-on-year in 2017

it is understood that ozone pollution has become another factor affecting the air quality of Chengdu after PM2.5, which can be used for tensile test, pressure test and bending test. The main factors causing ozone pollution include primary pollutants such as coal combustion and nitrogen oxides emitted by motor vehicle exhaust. To control ozone pollution, it is necessary to control the emission of nitrogen oxides and volatile organic compounds (VOCs). This is very similar to the governance of PM2.5. In the final analysis, it is to control emissions. To this end, the ozone pollution prevention and control action will strictly control the emissions of relevant enterprises. "Enterprises that cannot meet the emission standards will all stop production. For Koizumi, it will be changed, and open-air spraying is prohibited." The relevant person in charge of Chengdu Environmental Protection Bureau said

Chengdu listed June 16 to August 31 this year as the key prevention and control stage. During this key prevention and control period, Sanwayao power plant, steel, cement clinker and glass production enterprises limited production loads, and nitrogen oxide emissions decreased by 30% year-on-year. Enterprises in the chemical, brick and tile, textile, food and other industries limited production loads, and the emissions of nitrogen oxides from furnaces and boilers decreased by 30% year-on-year. Furniture manufacturing, printing bag conditioning screw to appropriate position; Tighten the oil return valve, shoe-making, pharmaceutical and other key volatile organic compounds emission enterprises, limit the production load, and the volatile organic compounds emission decreased by 50% year-on-year

in case of adverse meteorological conditions, Chengdu will further expand the scope of production restriction of enterprises to ensure that the emissions of volatile organic compounds and nitrogen oxides of enterprises with limited production will be reduced by 50% year-on-year

under the internal economic cycle, China Chengdu Construction Expo in April 2021 will talk to you. Please be sure to inspect the new opportunities in the industry first.

in 2020, with the outbreak of the global epidemic and the prevention and control of the domestic epidemic being effectively controlled, the global economic pattern has also undergone great changes, and China is moving forward under the strong strategic deployment of the national policy [details]
