Draw the "Normal Blue" of Port City, 173 days as of August 9th in Qinhuangdao, Hebei

Multiple co-governance draws Hong Kong City's "normal blue" ——As of August 9, the comprehensive air quality index of Qinhuangdao City was 4.51, and the number of days reaching the standard increased by 11 days over the same period last year

　　Hebei News Network (Hebei Daily reporter Shiyuan correspondent Shi Na) walked into the Qinhuangdao Yaohua Glass Technology Development Co., Ltd. factory area. The open roads and verdant vegetation make people feel like they are in a green park. According to Yang Xiaoping, deputy director of the Safety Management Department of Yaohua Group, all this stems from the company’s high attention to environmental protection, strict implementation of national, provincial, and municipal environmental protection laws and regulations, and the completion of the 2020 flat glass industry atmosphere in 2019. The transformation of ultra-low pollution emission standards has promoted clean production and in-depth treatment of pollutant emission reduction in enterprises, and strived to build garden-style factories.

　　The construction of the cold end garden plant area of ​​the production line of China Yaohua Glass Group Yaoji Company is a microcosm of Qinhuangdao City's in-depth promotion of the ultra-low emission transformation of the enterprise and the continuous victory of the "Blue Sky Defense".

　　For a long time, the Qinhuangdao Municipal Party Committee and the Municipal Government have attached great importance to air quality work, taking it as an important political task, and clearly demanding that green be the background color of Qinhuangdao and ecology as life, and economic development must not sacrifice ecology. The environment is the price. The main leaders of the municipal party committee and the municipal government have always adhered to front-line command and first-line dispatch. All county and district governments and relevant departments directly under the city keep an eye on key areas, highlight coordination and linkage, and strengthen environmental law enforcement. Last year, the city accelerated the promotion of in-depth governance of key industries. 21 key industry enterprises and 55 governance projects were completed successively, which promoted continuous improvement of air quality.

　　"This is the situation of our environmental protection parameters. Units 2, 3 and 4 are running, soot No. 2 is 0.9, No. 3 is 0.7, No. 4 is 0.56..." On August 11, the reporter came to Qinhuangdao Power Generation Co., Ltd. In the main control room, the display clearly shows the current emission values ​​of various pollutants such as smoke, sulfur dioxide, and nitrogen oxides. According to reports, last year the company invested 11 million yuan to implement in-depth treatment of nitrogen oxides. Before in-depth treatment, the emission of nitrogen oxides by enterprises is required to be below 50 mg per cubic meter, and after in-depth treatment, the standard is below 30 mg per cubic meter. “We focused on repairing the deflector, optimized the flow field, and added some deflectors to make the flow field more uniform.” said Zhang Jie, the company’s safety director, “Take Unit 3 as an example. Before treatment, the pollutant emission value was about 40, meeting the standard below 50. After in-depth treatment, the daily value was basically more than a dozen times, and it was roughly doubled."

　　In 2019, in addition to completing the 6 power industry transformation projects and 19 steel industry transformation projects required by the provincial government, Qinhuangdao City also actively planned 17 iron and steel industry transformation projects, 6 power industry transformation projects, and 3 projects. Pilot demonstration projects in the glass industry, 4 pilot demonstration projects in the cement industry.

　　Since the beginning of this year, the city has adopted the "5+2" governance mechanism, through the scientific analysis of the expert team, precise implementation of policies, and the iron fist of environmental law enforcement personnel to rectify and attack. In the in-depth implementation of the treatment project, 323 gas-fired boilers, 164 alcohol-based fuel boilers, and 345 biomass boilers were renovated, 119 industrial furnace projects, and 45 volatile organic compounds projects were in-depth treated; at the same time, they urged key industries and enterprises to complete the super Low-emission transformation, on the basis of meeting the emission standards, explored the total control mechanism for 57 key pollutant companies, and cumulatively reduced emissions of 302.5 tons of particulate matter, 503.6 tons of sulfur dioxide, and 1636.7 tons of nitrogen oxides.

　　In order to ensure the air quality during the peak tourist season, Qinhuangdao City will take intensified control measures to strictly control ozone precursors from July 25 to August 20, and implement nitrogen oxide concentration control measures in key periods in the region. "At the same time, the city's VOCs-related enterprises and the auto repair industry have in principle stopped the management and control of VOCs-related process operations during the day, and strengthened the control of construction sites and night muck trucks, catering oil fume control, heavy diesel vehicles and ports." Li Zhiyun, a staff member of the Office of the Municipal Leading Group for Air Pollution Prevention and Control Action, introduced that through a series of comprehensive treatments, the PM2.5 concentration was 17 micrograms/m3 from June 1 to August 9, a 32% drop from the same period last year; regional environment The air quality composite index was 2.82, a decrease of 10.5% from the same period last year.

　　Data shows that in the first half of this year, air quality has improved significantly. As of August 9, the comprehensive air quality index of Qinhuangdao City was 4.51, a year-on-year decrease of 16.9%; the number of days reaching the standard was 173 days, an increase of 11 days from the previous year.
