From: Lianyungang Daily Updated: 2023-01-30 03:03

Recently, the Ministry of Ecology and Environment reported the national ambient air quality situation in 2022, and our city ranked among the top 20 in terms of air quality changes in 168 key cities nationwide, with the rate of improvement ranking 18th.

Clarification of responsibilities at all levels

According to the relevant person in charge of the Atmospheric Division of the Municipal Ecological Environment Bureau, in recent years, based on "pollution prevention, pollution control, pollution reduction and pollution treatment", our city has strictly clarified the responsibilities of air pollution prevention and control at all levels, vigorously promoted the emission reduction of air pollutants, focused on industrial pollution control, fugitive dust control, mobile source control, cooking fume control of catering business, straw burning control, fireworks and firecrackers prohibition and micro-environment control and deeply carried out the emission reduction work of key industries and enterprises. Lianyungang Blue went viral on Wechat Moments. The city's "charm" is greater, which not only gives the city a new look, but also brings vitality.

Specialization in certain focus areas

Last year, all counties, districts and departments of the city worked closely together to overcome the difficulties. Focusing on the key areas and crucial links of air pollution control, they fought and won the battle of protecting the blue sky in depth, and eventually got a fruitful result - a historic breakthrough in air pollution control. The concentration of PM2.5 in the city was 30 micrograms per cubic meter, the highest level since the monitoring record, with a year-on-year decrease of 6.25%, and the improvement rate ranked third in the province. The air quality rate was 83.6%, and the absolute value ranked second in the province. The ozone concentration was 159 μ g/m3, ranking first in the province.

Reinforcement of source governance

We have made continuous efforts in the source governance of focus areas such as enterprise clusters, organic storage tanks, cleaning raw material substitution and etc. We have successively carried out the renovation of brick and tile, glass fiber reinforced plastics, casting and other industries. A combination of off-site supervision and on-site law enforcement was adopted to continuously carry out friendly emission reduction and reduce endogenous emissions. In view of the numerous enterprises, wide industry categories, time-consuming and labor-intensive manual troubleshooting, Guanyun County has implemented 24-hour monitoring, early warning and analysis of the power consumption of enterprises and the operation of pollution prevention and control facilities by installing power monitoring equipment in more than 120 enterprises above the designated size in the county by means of installing power monitoring equipment in production facilities and pollution control facilities to realize the supervision of the whole process of enterprises. "People’s efforts" and "technical protection measures" were combined to achieve accurate law enforcement, effectively urge enterprises to implement their main responsibilities, save energy, reduce emissions and protect the environment.

Innovation of regulatory methods

Scientific and technological means are used to innovate regulatory methods. With the aid of VOCs, particle laser radar and other navigation monitoring means, focus areas are monitored and traced, so as to find and deal with the problem of high pollution value at the first time. Through the establishment of a joint supervision mechanism for mobile sources and with the help of the Lianyungang motor vehicle inspection agency’s supervision joint meeting system, the information channel is unblocked, the outstanding problems are solved through coordination and the joint inspection is carried out regularly to further promote the elimination of diesel vehicles with national iii. How to find out invisible VOCs? Now, this is no longer a problem. Haizhou District systematically reconstructs the structure and mechanism of cooking fume prevention and control, and an intelligent catering renovation platform is built to track the trace of VOCs in time. Zhang Runsheng, head of the Atmospheric Ecological Environment Section of Haizhou Ecological Environment Bureau, introduced that they actively promoted the installation of the online system of cooking fume, grasped the information of cooking fume emission in real time, pushed forward the transformation from "offline remediation" to "cloud monitoring" and promoted the strict, practical and rapid resolution of cooking fume pollution.
