In the streets and alleys of the Fangshan district, the small white boxes hanging from the walls and lamp posts, although only the size of a book, can monitor PM2.5 data every 10 minutes and send it back. to the ecology of the district in real time. Office of the Environment. It is a device for monitoring atmospheric polluting particles. There are 550 in the whole district, covering all villages and natural communities. They are like the “eyes” of Fangshan District’s refined atmospheric management platform. By analyzing big data, they can always keep “normal” for citizens. blue”.
In recent years, Fangshan District has continuously made large investments in establishing a “2 + 24 + 550” scale “district-town-village” three-level automatic atmospheric environment monitoring network system, and 92 coarse particles that cover all the streets and towns of the district. The monitoring stations and the air quality monitoring network are leaders in the city. At the same time, an automatic monitoring platform for atmospheric PM2.5 was simultaneously designed and developed. Through the “Fangshan Air” APP, the concentration and changes of PM2.5 and TSP are tracked in real time. The characteristics of the pollution are analyzed based on the monitoring data, and the pollution source is precisely tracked to give full performance to the atmosphere. Compass function for monitoring.
Through the systematic and institutionalized construction of refined atmospheric management measures and the application of refined atmospheric platform support, the ambient air quality in Fangshan District has improved significantly. According to Liang Xin, Section Chief of the Environmental Management Section of the Fangshan District Ecological Environment Office, in 2016, the PM2.5 concentration of the Fangshan District was 83 micrograms / m3, which qualifies the inverse of the city. Last year, this data fell to 42, and the city ranked ninth this year. From January to August, it fell back to 38, completing the magnificent transformation from 83 to 38, ranking seventh in the city, not only settling stable in the middle of the city, but also successfully removing the “hat” from account. regressive city.
Similarly, Fangshan also gave his own answer in terms of “water control”. The Dashi River is the mother river of Fangshan District, but the water quality was poor before 2018, affecting the lives of the surrounding people. In order to completely remove the label that the Dashi River does not meet standards, the district government established the Fangshan District Water Pollution Coordination Management Lead Group to coordinate the water environment management work , focusing on “inspection, testing, tracing, punishment, treatment and management”, and cracking down on restrictions The key and difficult issues of environmental water governance. Through monitoring data, water quality analysis is carried out every week to form a weekly report for district leaders and related units, which are uniformly sent by district leaders to form a system governance of “follow-up-analysis-search for problems-suggestion of countermeasures”. At the same time, strengthen law enforcement along key rivers and tributaries, and adopt measures such as linking enforcement in inspections to strengthen sanctions and use sanctions to promote governance and reforms.
At the same time, sewage treatment facilities have been built in key cities such as Doudian and Liulihe to compensate for the shortcomings of the treatment facilities. The current wastewater treatment capacity of the entire district has reached 250,000 tons per day. “In the next step, we will build an online monitoring system, implement refined management of pollution sources, sewers and rivers in three points and one line, and use scientific and technological means to achieve ‘scientific, refined management and normalized ‘the aquatic environment, as well as precise combat and governance. The pollutant discharge behavior further improves the quality of the regional aquatic environment, “said Liang Xin.
