Beijing comprehensively eliminates five types of water quality sections
Author:Beijing released Time:2022.07.05
In the south of Beijing, a clear river connects Daxing from west to east, Beijing Economic and Technological Development Zone, and Tongzhou. In just a few years, the new Fenghe River of the "Mosquito River" has been perfectly transformed, and it has become a green ecological corridor with clear shores. The full -process control of pollution is achieved through new sponge facilities, storage tanks, and construction of artificial wetlands at two estuaries. The reporter learned that Xinfeng River is the epitome of Beijing's "water control". In recent years, Beijing has led the "river length system", pollution reduction and ecological expansion. The water quality of the surface of Beijing has continued to improve, and the five -type water quality section was completely eliminated.
In the past "Longxugou"
Now the river flows eastward
Xinfeng River is an important flood control and drainage and landscape viewing river in the north of Daxing District. The total area of the basin is 166.4 square kilometers. As the main component of the "Water Three Rings" of the "Three Ring Water System Water" in Beijing, Xinfeng River is an important ecological corridor connecting Huangcun, Yizhuang and Tongzhou City, which is connected to the southern part of Beijing.
Since the 1980s, with the rapid development of socio -economic development, the extensive production methods have contaminated the Xinfeng River, the river is dry and black, and the ecosystem is severely damaged. hat of. In order to completely solve the problem of the water body of the new Fenghe River, under the coordinated leadership of the Municipal Party Committee and the Municipal Government, the Daxing District Party Committee and the District Government took the opportunity to supervise and renovate, and closely collecting and treating facilities around sewage. Enter the river sewage outlet management, make every effort to improve the key tasks such as the water quality of the section of the section, and comprehensively open the riverside governance ecological repair battles.
Comprehensive pollution
Make up the shortcomings of the construction of pollution control facilities
In 2017, Xinfenghe began a new round of governance, and the PPP project of the basin comprehensive management was officially launched. First cut pollution, then improve the quality of water, and realize the restoration of the ecology, and become a established strategy of governing the river.
Reduce pollution, and the pollution -cutting control is the first to start. In terms of centralized treatment of sewage, Daxing District has tightly built the treatment facilities of sewage collection and treatment facilities, and completely solves the problem of exogenous pollution through the control source interception project of the four modes of villages, towns, villages and villages, and single villages. Niu Yina, deputy general manager of Beijing Beichang Xingfeng Water Environmental Governance Co., Ltd. introduced that at present, the Xinfeng River project is about 54 kilometers through the river dredging, and the new sewage interception pipeline is 22.75 kilometers to build three sewage treatment stations to achieve endogenous pollution control; Build a sponge facility, two first rain storage ponds, and two river port artificial wetland to achieve the entire process of pollution control.
At the same time, the comprehensive governance project in the river mouth in the Xinfeng River Basin's facial source of the river basin has built the two artificial wetlands of Xinxi Fengqu Wetland and Annan branch wetland respectively. It is reported that the wetland park covers a total area of 780,000 square meters, and the processing scale reaches 78,300 cubic meters per day. The noodle pollution carried by Nanyuan irrigation canal, Xinxi Fengqu, and Annan tributaries "purified first, and then entered the Xinfeng River" to ensure the healthy and stable water quality of the Xinfeng River dry flowing ecosystem.
At present, Daxing District rationally uses recycled water to implement a daily ecological hydration of 127,000 cubic meters through the water system connection project to ensure that the dry tributary is flowing and live water. The self -purification capacity of recycled water is limited, which requires plants, water creatures and fish in water to make the water "live" a little bit. At present, the coverage of the Xinfeng River's aquatic plant has reached about 40%; the large -scale benthic animals have recovered well, the types and quantities of birds are gradually increasing, and the biodiversity of water ecosystems has increased significantly.
Innovation mechanism
Guarantee the long -term clearing of the basin
In order to ensure the long -term governance of Xinfeng River, the main leaders of the Daxing District Party Committee and the District Government led, in accordance with the requirements of "party and government responsibility", "one post and two responsibilities", and guided by problems, adhere to daily inspections, special inspections, and early warnings Inspection, interviewing inspections, accountability inspections "five steps" supervision and supervision mechanism, inspectors all groups of members to form a large network of inspections in the region, carried out 30.1 kilometers around the river, as well as pollution behavior around the river. Essence The problems found, especially the prominent environmental problems, and conduct special inspections, and conduct review in accordance with the time limit for rectification, timely grasp the improvement of improvement, promote the implementation and problem resolution of various types of pollution problems, and improve the quality of the rectification of the problem as a whole.
Xinfenghe is just a microcosm of Beijing's water control. Huang Bin, deputy director of the Water Ecological Environment Department of the Beijing Municipal Bureau of Ecology and Environment, introduced that in recent years, the Municipal Ecological Environment Bureau has strengthened dispatch and regularly convened relevant municipal departments to hold a working joint meeting to jointly study issues, coordinate countermeasures, and promote implementation. The municipal ecological environment inspection department went to Xinfenghe several times to investigate, and inspected the inspection and patrolling the comprehensive rectification progress of Xinfenghe. Implement a beautiful rural construction plan with the theme of "pollution control". Implement the compensation mechanism for cross -regional and cross -district water environment and regional regional regional regional regions to form a pattern of upstream and downstream grasping the co -governance environment.
