A kind of river sewage treatment method

Abstract

The invention provides a river sewage treatment method. An aeration device, a bottom net, connecting ropes and a floating net are matched to finish the operation. The problems that the growth of planktons is inhibited, the ecological environment of rivers is destroyed, the water quality is further deteriorated, the flowing of water is possibly limited by the random production of aquatic plants andthe like due to insufficient illumination of the water body, stinking and reduction of the oxygen content in the water caused by the fact that a large number of aquatic plants breed and occupy a river channel are easy to occur when aquatic plants are randomly put into a river channel during riverway treatment without control, can be solved by the method.

Description

technical field [0001] The invention relates to the field of river sewage treatment, in particular to a method for treating river sewage. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. In order to reduce production costs, some factories directly discharge pollutants into inland rivers through sewage outlets, resulting in black and smelly river water. Especially in large and medium-sized cities in developed areas of our country, the problem of black and smelly rivers has become quite prominent; [0003] In order to treat river sewage, the river sewage is usually purified and treated by planting aquatic plants, but this approach often has some problems: [0004] Randomly put aquatic plants into the river, without control, it is easy to cause a large number of aquatic plants to multiply, cau...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a river sewage treatment method, which can solve the problem of randomly putting aquatic plants into the river during river treatment. If it is not controlled, it is easy to cause a large number of aquatic plants to multiply, causing the river to be full. As a result, the water body has insufficient light, becomes smelly, and the oxygen content in the water is reduced, thereby inhibiting the growth of plankton, destroying the ecological environment of the river, and further deteriorating the water quality, and the wanton production of aquatic plants may limit the flow of the water body, etc. question
