Background

In recent years, the speed of the urbanization process development of China is high, and the urban river is more and more emphasized by people as an important landscape of the city. However, for a long time, the urban river channels in our country emphasize their functions of waterlogging prevention and flood discharge, but neglect their ecological and landscape functions, which results in less treatment of river channel landscape, and the river channels are polluted by pollution sources for a long time, resulting in the reduction of water quality. Not only the urban landscape is influenced, but also the urban image is damaged, and the living environment of people is greatly influenced. Therefore, the method has extremely important significance for strengthening the treatment of urban river channels, maintaining the ecological environment of cities, beautifying the landscape of the cities and improving the living environment of people. The national requirements on environmental protection are increasingly strict at present, domestic sewage plants in various cities are sequentially improved to the numerical value of the first class A of pollutant discharge standard of the urban sewage treatment plant, and the requirements on ammonia nitrogen in the process of improving the standards are improved to 5 (8) mg/L; the ammonia nitrogen standard of the river V-type water is 2 mg/L.

The causes of the urban black and odorous river channel mainly comprise: 1, domestic wastewater enters a river channel, 2 pollutants carried by initial rainwater and 3 industrial sewage are discharged; in recent years, with the increase of urban environment treatment strength, the black and odorous problem of urban river channels is effectively remedied, and a more obvious effect is achieved. In the process of remediation, different remediation methods are required according to different pollution sources, and a physical method (artificial oxygenation, river channel dredging, water diversion and water replenishing) and a chemical method (chemical algae removal) and a biological ecological method are roughly adopted; the methods have advantages and disadvantages, and the problem of black and odorous river channels cannot be restrained from the root source.

Therefore, there is a need for a long-term effective treatment method and method with good sewage treatment effect, and a sewage treatment system with river biological diversity is started from the source.
