"Temperament" can reflect the quality of the ecological environment of a region.
In 2023, the comprehensive ambient air quality index of Lanshan District will be 428, the number of good days is 288 days, PM25 concentration 336 g m, no improvement rate in the city, o concentration in the city the lowest, to achieve three consecutive years of comprehensive and stable national ambient air quality level two standards, two consecutive years of no heavy pollution weather, "Lanshan blue" background color is purer, green water and green mountains are more colorful.
As the main position of the city's heavy industry, the air quality has reached the standard year after year, how did Lanshan District do it?
In recent years, Lanshan District has steadily promoted the prevention and control of air pollution, adhered to precise pollution control, scientific and technological pollution control, and pollution control in accordance with the law, worked hard and worked hard for a long time, making "Lanshan Blue" a new normal.
Since 2021, Shandong Iron and Steel Rizhao Company and Rizhao Iron and Steel have been rated as national green factories and provincial green factories respectively, and have fully completed the ultra-low emission transformation of the steel industry; Shandong Iron and Steel Co., Ltd. is the first A-level long-process steel enterprise in Shandong Province with environmental protection performance, and Nippon Steel Co., Ltd. has passed the acceptance of A-level environmental performance enterprises organized by the Provincial Department of Ecology and Environment, and has been selected as the first batch of collaborative innovation pilots for pollution reduction and carbon reduction in Shandong Province; Rizhao Iron and Steel Industry Cluster (Rizhao Advanced Iron and Steel Manufacturing Base Production and Smelting Zone) was approved as the first batch of pilot projects in the province and the first park and industrial cluster in Rizhao City for overall clean production audit and innovation; The ultra-low emission transformation of the coking and cement industries has been fully completed, and 37 air pollution prevention and emission reduction projects and 10 carbon monoxide treatment projects have been completed.
In order to strengthen the ecological environmental protection and air pollution prevention and control work in the whole region, the Lanshan District Party Committee and the District ** have set up a special class for air pollution prevention and control and a special class for the smooth service guarantee of the south coastal road, giving full play to the role of overall planning and coordination, and comprehensively carrying out daily inspections and problem supervision of outstanding environmental problems in key areas. More than 10 special key work meetings have been held, air pollution prevention and control work has been arranged, and a series of air pollution prevention and control plans have been issued, such as the "Ambient Air Quality Standard Plan for Lanshan District, Rizhao City (2021-2025)", "Blue Sky Defense Plan for Lanshan District, Rizhao City", and "Implementation Plan for Air Pollution Prevention and Control in Lanshan District in 2023", which provide a strong guarantee for the development of pollution prevention and control in the whole region.
With the improvement of ambient air quality as the core and the synergy of pollution reduction and carbon reduction as the starting point, Lanshan District focuses on the management and control of industrial enterprises, ports, construction sites, roads, mobile sources and other fields, and builds a "one-game chess" pattern for pollution control.
In terms of industrial enterprises, we have steadily promoted the special treatment of VOCs, carried out special inspection actions for ozone pollution control, and inspected more than 130 industrial enterprises and gas stations related to VOCs.
In terms of dust control, we will carry out special actions such as the "100-day attack" for dust pollution control in Lanshan District and the centralized action for dust pollution control, and establish a closed-loop working mechanism of "assignment, rectification, supervision, review, and sales".
In terms of mobile sources, we have continuously improved the joint supervision mechanism of "environmental protection forensics, public security penalties, and traffic maintenance", carried out joint law enforcement by departments, and sampled more than 340 diesel trucks and more than 300 non-road mobile machinery.
On the road to pollution control, Lanshan District has strengthened smart management, promoted precise pollution control, accurately traced the source through scientific and technological means such as lidar, navigation vehicles, and drones, explored and implemented the "documentary" work method for air pollution prevention and control, and "technical defense + civil air defense" to help precise pollution control.
At the same time, Lanshan District has strengthened the forecast of ambient air quality, hired an expert technical team to release air quality early warning information regularly, paid attention to site monitoring data in real time, put forward early warning information for air quality forecasting, analysis and judgment, command and dispatch, daily inspection and analysis, and formulated control suggestions, providing detailed data and technical support for scientific control and precise pollution control, and making every effort to ensure that the ambient air quality is stable and up to standard, and the blue sky happiness in Lanshan District has been significantly enhanced.
