Tianjin fully implemented in 6 major areas of 17 measures to prevent and control ozone pollution

Recently, the air is fresh and pleasant, and the blue sky is very eye -catching. The white clouds float by the wind, attracting many citizens to stop taking pictures. It is learned from the ecological environment department of our city that in summer, high -temperature weather has exacerbated ozone pollution near the ground, and ozone has become an important pollutant that affects air quality. This has also become the focus of air quality monitoring and governance in our city's ecological environment department.

Our city issued a special action plan for ozone pollution prevention and control in 2022. Until October this year, it continued to do a good job of summer oxygen tackling operations, focusing on volatile organic matter (VOCS), nitrogen oxide targeting and precise prevention and control, and fully implemented the control and control of key industries emission control and control , 17 measures, including mobile source control, refined management control, special law enforcement supervision, and strengthening command and dispatch.

Wang Wenmei, director of the Atmospheric Environment Department of the Municipal Ecological and Environment Bureau, said that the city's organization implemented low (no) VOCS content of the original and auxiliary materials of the original and auxiliary materials to strengthen pollution control. The 37 companies replaced by the newly completed source were conducted dynamically to conduct dynamic verification, and continued to promote industrial painting and printing enterprises to carry out VOCS raw and auxiliary materials replacement. Complete the upgrade and transformation of 293 low -efficiency VOCS governance facilities of 242 companies. Carry out comprehensive governance of VOCS Industrial Park and corporate cluster, establish a list of bills, and promote the formulation of green upgrade and transformation plan. Especially in combination with the characteristics of the city's industry, the city's dynamic investigation and update list of tanks in the city is established to carry out on -site assistance inspections of more than 690 tanks such as petrochemicals, chemicals and warehouses. No organizational emission governance.

At the same time, we will strengthen forecasting and forecasting. Relevant scientific research institutions and experts will carry out air quality monitoring forecast daily, and encrypt frequently during continuous high temperature periods, and timely study the trend of air quality changes, pollution sources, time and space distribution changes, and transmission characteristics. Sexual pollution peak -cutting measures are supported. "When predicting continuous ozone pollution, the city Blue Sky Office organizes a special response mechanism to schedule a high -value area of ​​the ozone concentration every 2 hours, and timely report the typical pollution problems found in time, and continue to release the work dynamics." Wang Wenmei said.

According to reports, combined with satellite remote sensing -related data, daily pushing the city's pre -ozone satellite remote sensing monitoring daily during the high temperature period, screening VOCS high -value zones, refining the specific industrial parks sex. During the on -site inspections, with the help of a flight car, the high -value retrospective was used to make full use of infrared cameras and portable testing equipment to help companies find weak pollution control links and improve pollution control capabilities and levels.
