Sewage treatment reaction tank and sewage treatment purification system

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment reaction tank and a sewage treatment purification system. The sewage treatment reactiontank comprises a tank body, a water inlet is formed in the position, close to the top, of one side of the tank body, and a blow-down valve is arranged at the position, close to the bottom, of the other side of the tank body. According to the invention, a supporting plate hinged to the tank body is arranged at the bottom of the tank body, and when sludge in the tank body is discharged from the blow-down valve, a compressed supporting spring can be restored, the supporting spring pushes the supporting plate to be in an inclined state again, sludge remained on the supporting plate can be discharged from the blow-down valve along the inclined supporting plate, and the sludge residue is reduced. Meanwhile, when the free end of the supporting plate rotates upwards, the bottom end of a water receiving plate can be pushed to move towards the middle of the supporting plate, and when the bottom end of the water receiving plate slides on the supporting plate, sludge on the upper surface of the supporting plate can be pushed, and discharging of the sludge is accelerated. In this way, the sludge can be cleaned in time, and extra energy consumption is not needed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment reaction pool and a sewage treatment purification system. Background technique [0002] With the acceleration of urbanization in rural areas, the problem of water pollution has become increasingly prominent, and has become a new hot spot after sewage treatment in large and medium-sized cities. Its effectiveness will directly affect the overall condition of my country's water environment and the quality of harmonious development between man and nature. Sewage treatment in small rural towns in my country really originated from the treatment of the Three Gorges Reservoir area, and it is worth analyzing and thinking about the existing difficulties and problems so far. Due to historical reasons, the infrastructure in rural towns is very weak, and the sewage treatment project is a highly comprehensive systematic project. In addition to regional differences a...

Problems solved by technology

[0004] When the above two activated sludge methods are used to treat rural sewage, due to the particularity of rural sewage - there is a lot of soil, when treating rural sewage, there are many impurities that settle to the bottom of the reaction tank. After the water is discharged, the impurities at the bottom need to be cleaned by electric devices. On the one hand, it cannot be cleaned in time
