Technical Field

[0002] With the gradual acceleration of the industrialization and urbanization processes, the aggregation of the population and the change of the underlying surface have gradually increased the pressure on the regional water environment. The non-point source pollution of surface runoff generated by rainfall and the point source pollution such as domestic sewage brought about by imperfect sewage interception enter the river. After several rounds of pollution control, although it has improved, it is necessary to regularly maintain the purification of the river water body. The water pollution in the river is mainly the excessive pollution of organic pollutants. Excessive organic pollutants and insufficient dissolved oxygen cause the water body to be black and smelly due to the malodorous gas and black liquid generated by anaerobic decomposition.

[0003] Although the existing river sewage purification usually adopts the methods of cultivating bacteria and planting green plants, its structure can only cover the areas close to the river surface and in sufficient contact with the air. Not only is the vertical space utilization rate low, but it also cannot act on the deep part of the river. In view of the above related technologies, the applicant proposes a river sewage purification structure, which can not only act on the area where the river surface is in contact with the air, but also cultivate aerobic bacteria in the deep part of the river to decompose harmful substances, and more three-dimensionally control river pollution.
