Domestic sewage treatment device

Abstract

The invention discloses a domestic sewage treatment device. The device comprises a main equipment body, wherein a plurality of supporting legs are fixedly connected to the bottom of the main equipment body, a plurality of anti-skid bases are fixedly connected to the bottoms of the supporting legs, a water inlet pipeline is fixedly connected to the upper end of the side wall of the main equipment body, external threads are arranged on the surface of the water inlet pipeline, a water outlet is fixedly connected to the bottom of the side of the main equipment body, an impurity removal barrel is fixedly connected to the bottom of the inner wall of the main equipment body and fixedly connected with the water outlet and the water inlet pipeline, and a connecting shaft is fixedly connected to the bottom of the inner wall of the impurity removal barrel. Compared with the prior art, in the moving process of an extrusion shaft, the surface of an air pressure ball can be extruded, a driving ball can extrude the surface of an elastic ring, and the extrusion shaft can be matched to extrude the outer wall of the elastic ring, so elastic bristles can clean the interior of a sieve plate when the equipment filters sewage; namely, the filtering efficiency of the device can be improved, the maintenance period of the device can be prolonged, and sewage treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment device. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic substances. ...

Problems solved by technology

Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic substances. Domestic sewage will contain various non-degradable substances such as plastic bags. Substances, this kind of impurities will not only cause the blockage of the screen, but also easily entangled on the internal structure of the equipment, resulting in damage to the equipment. Therefore, we propose a domestic sewage treatment device to solve the above problems
