Sewage tank with filter assembly and working method thereof

Abstract

The invention discloses a sewage tank with a filter assembly and a working method thereof. The sewage tank comprises a sewage tank main body, a filtering assembly is fixed in one side of the sewage tank main body, a stirring assembly is fixed in the middle of the sewage tank main body, a connecting block is welded and fixed to the side face of a tank body on one side of the sewage tank main body,and a feeding assembly is fixed in one side of the connecting block; the filtering assembly comprises a tank door mounted in one side of the sewage box main body; a sealing plate is welded and fixed on the side surface of one side of the tank door corresponding to the sewage tank main body; air cylinders are symmetrically embedded into the top end and the lower end of the sewage tank main body; according to the sewage tank, multiple times of filtering can be conducted, the filtering effect is improved, impurities on the filter screen can be conveniently removed, the filtering effect of the next sewage is improved, heavy metal in the sewage can be conveniently filtered, the filtering effect is improved, lime and the sewage can be conveniently and completely mixed, heavy metal discharging isavoided, and the environment is prevented from being polluted.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, in particular to a sewage tank with a filter assembly and a working method thereof. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse; sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields have increasingly entered the daily life of ordinary people, and when treating sewage, sewage tanks need to be filtered. [0003] However, the filtering effect of the existing sewage tank filter device is generally not good, because various impurities inside the sewage are not easy to filter clean, and the impurities on the filter screen are not cleaned in time after filtering, resulting in poor filtering effect in the next step; [0004] ...

AI Technical Summary

Problems solved by technology

[0003] However, the filtering effect of the existing sewage tank filter device is generally not good, because various impurities inside the sewage are not easy to filter clean, and the impurities on the filter screen are not cleaned in time after filtering, resulting in poor filtering effect in the next step;

[0004] And there is no feeding device, because the sewage often contains a large amount of heavy metals, if it is discharged without treatment, it will pollute the environment and cause ecological damage;

[0005] Moreover, there is no stirring device, so that when the lime enters the sewage tank, it cannot be completely mixed with the sewage, and the reaction effect with heavy metals becomes lower, and the reaction of heavy metals is incomplete, resulting in some heavy metals being discharged and causing environmental damage.
