Sewage treatment equipment

Abstract

The invention discloses sewage treatment equipment which comprises a treatment box, a water inlet pipe and a drainage pipe, the water inlet pipe is fixed in the center of the top of the treatment box, the drainage pipe is arranged in the center of the bottom of the treatment box, and the water inlet pipe and the drainage pipe are both communicated with the treatment box. The driving rotating shaft is rotatably connected between the two corresponding sides of the inner wall of the treatment box and is close to the top, the crushing devices are fixed to the surface of the driving rotating shaft, the crushing devices are evenly distributed on the surface of the driving rotating shaft and are located at the end of the water inlet pipe, and the filter screen device is fixed to the inner wall of the treatment box and is close to the bottom; and the invention relates to the technical field of sewage treatment. According to the sewage treatment equipment, the purposes of crushing sand balls and preventing blockage are achieved, the sand balls which are bonded into balls can be crushed in time, impact on the equipment is reduced, the service life of the equipment is prolonged, meanwhile, blockage can be prevented, the filtering effect is good, and the using performance is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment. 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. With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a kind of sewage treatment equipment, which solves the problem that when filtering, sand will stick together with silt or sticky matter to form a lump, and the gravity will increase a lot. Bending or deformation, setting will cause damage, affect the service life, and affect the filtration efficiency at the same time, and the sticky matter is easy to cause blockage, which makes the filtration work unable to proceed normally and reduces the problem of performance
