Sewage purification treatment device for aquatic environment engineering and mounting method

Abstract

The invention relates to the technical field of aquatic environment engineering, and particularly discloses a sewage purification treatment device for aquatic environment engineering and an installation method.The sewage purification treatment device comprises a water retaining assembly and an adjusting assembly, the water retaining assembly comprises a water retaining dam and a water level fall detection unit installed on the water retaining dam, and the water retaining assembly is installed at the junction of a T-shaped river channel; the water retaining assembly is arranged at a water outlet of the pond, and the power generation assembly comprises two first power generation units installed on the water retaining assembly and a second power generation unit installed on the adjusting assembly; water flow of the main river channel enters the branch river channel, water flow of the branch river channel enters the main river channel and water of the pond enters the branch river channel, so that good water circulation is formed, namely sewage is purified through the natural purification function of the river channel, and impact force of the water flow can be utilized for power generation in the water circulation process. The device not only can purify the sewage by accelerating the water circulation of the T-shaped river channel, but also can utilize the impact force generated by the water circulation to generate power and save energy.

Description

technical field [0001] The invention relates to the technical field of aquatic environmental engineering, in particular to a sewage purification and treatment device for aquatic environmental engineering and an installation method. Background technique [0002] The aquatic environment refers to the environment with water such as rivers, lakes, wetlands, etc. In the process of river channel management of aquatic environment, the general treatment direction is to clean up the main channel. However, due to the connection between the main channel and the branch channel, the aquatic environment of the branch channel will affect the aquatic environment of the main channel to a certain extent. Therefore, in the process of river management, both the main channel and the branch channel need to be treated. [0003] However, in some areas, due to the previous river management, many branch channels have been dug manually. Under the influence of the reconstruction of ponds, the construc...

Problems solved by technology

[0003] However, in some areas, due to the previous river management, many branch rivers have been manually dug out. Under the influence of factors such as pond reconstruction, road construction, and river water plant reproduction, these branch rivers will be blocked, thus forming T-shaped rivers, and in T-shaped rivers, due to the small width of the branch rivers, water changes in the aquaculture ponds, and the accumulation of aquatic plants, it is easy to make the water in the branch rivers that is not easy to circulate turbid and smelly

The water quality of the branch river is turbid and smelly, which will affect the water quality of the aquaculture pond. When the water quality in the aquaculture pond cannot be improved through the water flow of the branch river, the pond near the main river will choose to lengthen the water inlet pipe , while the ponds far away from the main river channel will choose chemical improvement, and chemical improvement can treat the symptoms but not the root cause, and it is easy to make the water in the pond eutrophic, and the water in the pond will be discharged into the branch river after the eutrophication. It will make the aquatic plants more lush, and some aquatic plants will greatly affect the aquatic environment, thus forming a vicious circle
