Sewage treatment pretreatment tank with aeration ball repeatedly moving along horizontal plane

Abstract

The invention discloses a sewage treatment pretreatment tank with an aeration ball repeatedly moving along a horizontal plane. The tank comprises a tank body, a drain pipe and a filter box. The lowerend of the right side wall of the tank body is fixedly connected with the drain pipe, and the left side of the tank body is fixedly connected with the filter box. A water inlet pipe is fixedly connected to the rear side wall of the filter box, and a water conveying pipe is welded to the lower end of the filter box. A discharging plate is hinged to the inner side wall of the lower end of the filterbox, and a first hydraulic rod is fixedly connected to the right side wall of the lower end of the filter box. Movable frames are clamped to the upper ends of the front side wall and the rear side wall of the tank body, and telescopic plates are slidably connected to the inner sides of the movable frames. According to the sewage treatment pretreatment tank with an aeration ball capable of repeatedly moving along the horizontal plane, impurities in sewage can be conveniently subjected to multiple filtering treatment, the filtered impurities can be conveniently cleaned, and the practicability of the pretreatment tank is improved; and in addition, the aeration ball can conveniently repeatedly move along the horizontal plane, and the biological treatment efficiency is improved.

Description

technical field [0001] The invention relates to the related technical field of sewage treatment, in particular to a pretreatment pool for sewage treatment in which popping balloons repeatedly move along a horizontal plane. Background technique [0002] With the continuous improvement of energy conservation and environmental protection awareness, the requirements for sewage treatment are also more stringent. Sewage treatment is a complex operation process that requires a series of treatment methods such as filtration treatment, chemical treatment and biological treatment. Sewage treatment is used in construction, agriculture, etc. and energy fields are widely used. [0003] When the sewage enters the pretreatment tank, it often needs to be filtered and then biologically treated by the popping balloon. However, the pretreatment tank used in the background of the prior art still has certain shortcomings, such as: [0004] 1. The existing pretreatment tank is not convenient for...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a kind of pretreatment tank for sewage treatment in which the popping ball moves repeatedly along the horizontal plane, so as to solve the inconvenient multiple filtration treatment of impurities in sewage proposed by the above-mentioned background technology, and it is inconvenient to filter the impurities after filtering Cleaning reduces the practicability of the pretreatment pool. In addition, it is inconvenient for the popping ball to move repeatedly along the horizontal plane, which reduces the efficiency of biological treatment.
