River monitoring renovation in progress

The water is clear, the water plants are luxuriant, and under the sunshine, it is full of greenery... This is the scene that the reporter saw at the boundary river at the west end of the new city. The visual experience of fish playing with lotus leaves. 'After upgrading and transformation, the transparency of the water body in the deep water area of ​​the boundary river in the west has reached more than 1.5 meters.' Yao Bin, chief of the river channel section of the Xincheng Public Utilities Management Center, introduced that in July last year, Xincheng launched the river quality improvement project around the administrative center square of the city. The river course includes 7 rivers: Square South River, Square West River, Square North River, Xizhijie River, Shangheqiao River, Lijiatang River and Dongzhijie River, with a total water area of ​​about 51,500 square meters and a total water volume of 77,300 cubic meters. At present, the quality of the 7 rivers has been improved, entering the 'quality era', and complementing the surrounding quality roads such as Tiyu Road and Haiyu Road. Yao Bin, Section Chief of the River Section of the Xincheng Public Utilities Management Center is different from the previous river water quality improvement process. This time the river quality improvement focuses on 'ecology'. On the basis of retaining the original floating islands and aeration devices, the river bottom Governance as a focus for improvement. Eliminating pollution sources is also the key to improving river quality. In the past, sewage from restaurants along Yidao Road and Tiyu Road in the new city often flowed into rivers through broken pipes. This time, the new city has carried out sewage interception and management on Yidao Road, Haiyue Road, Haiyu Road and other road sections. At the same time, it hired a third-party company to build an ecological filter wall at the confluence of the river for pretreatment to further improve the quality of the river. At present, the quality of the seven rivers has been improved, and the water in some rivers has even reached the second-class drinking water standard after testing. It is understood that the 'underwater forest' built by submerged plants and the ecological filter wall are the main highlights of the 'quality river' construction. The 7 'quality rivers' all use three kinds of water-purifying submerged plants, Hydra verticillium, four-grade licorice, and syringa, which can not only absorb nitrogen, phosphorus, and refractory organic pollutants in water bodies and sediments , transform, and synthesize its own substances, which can purify eutrophic water bodies, and can adjust the material circulation rate of water ecosystems, increase water body biodiversity, and control algae growth, thereby effectively improving water quality and ecological environment. The ecological filter wall uses porous carriers of different pore sizes to filter or absorb sediment, particulate matter, and suspended matter in the water body to enhance the water purification effect. In the next step, Xincheng will continue to consolidate the achievements of 'quality rivers', promote the implementation of the municipal government's internal sewage pipe network restoration project, do a good job in the daily maintenance and management of quality rivers, and make the river landscape a beautiful scenery in the city. Yao Bin said that washing sundries, fishing, free release of wild animals, and random discharge of sewage and littering are prohibited in the 'Quality River'. He hopes that the citizens will actively cooperate. Quality rivers need you and me to maintain together! It is forbidden to wash sundries, fish, release wild animals at will, discharge sewage and throw garbage indiscriminately.
