A pretreatment tank for sewage treatment with popping balls moving repeatedly along the horizontal plane

Abstract

The invention discloses a pretreatment tank for sewage treatment in which an explosive balloon moves repeatedly along a horizontal plane, comprising a tank body, a drainage pipe and a filter box. The lower end of the right side wall of the tank body is fixedly connected with a drainage pipe, and the left side of the tank body is A filter box is fixedly connected to the side, a water inlet pipe is fixedly connected to the rear side wall of the filter box, and a water delivery pipe is welded to the lower end of the filter box, and a blanking plate is hinged on the inner side wall of the lower end of the filter box, and the filter box is A first hydraulic rod is fixedly connected to the right side wall of the lower end of the tank, and the upper ends of the front and rear side walls of the pool body are snap-connected with a movable frame, and the inner side of the movable frame is slidably connected with a telescopic plate. The pretreatment tank for sewage treatment in which the explosive ball moves repeatedly along the horizontal plane is convenient for multiple filtration treatment of impurities in the sewage, and it is convenient to clean the filtered impurities, which improves the practicability of the pretreatment tank. Repeated movement along the horizontal plane improves the biological treatment efficiency.

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.
