A kind of sewage treatment equipment

Abstract

The invention discloses sewage treatment equipment which comprises a sewage pipeline, a filter part arranged on the sewage pipeline, an adjusting device arranged at the lower part of the sewage pipeline, a discharging device arranged at the upper part of the sewage pipeline, and a protecting part arranged on the discharging device; the filter part comprises two filter tanks arranged on the sewagepipeline and two filter screens respectively arranged on the two filter tanks; the filter screens can move relative to the filter tanks. Through the arrangement of the filter tanks and the filter screens, when the filter screens of the sewage pipeline are replaced, sewage discharge does not need to be stopped, the efficiency of replacing the filter screens is improved, and the situation that sewage leaks when the filter screens are replaced is avoided.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to sewage treatment equipment. Background technique [0002] 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. In addition to destroying the ecological environment, sewage will also enter the human body and affect human health. [0003] In the prior art, filter screens are generally installed inside the sewage pipes, and the replacement of the filter screens requires relatively cumbersome steps. At the same time, when replacing the filter screens, it is necessary to temporarily stop the discharge of sewage in the pipeline, thereby slowing down the flow o...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, filter screens are generally installed inside the sewage pipes, and the replacement of the filter screens requires relatively cumbersome steps. At the same time, when replacing the filter screens, it is necessary to temporarily stop the discharge of sewage in the pipeline, thereby slowing down the flow of sewage. Processing efficiency

[0004] At the same time, when sewage is discharged, the existing sewage pipelines often discharge industrial sewage and domestic sewage into the same area, which causes inconvenience in subsequent sewage treatment and affects the effect of sewage treatment

[0005] In the prior art, adding flocculants to sewage is a commonly used sewage treatment method, and generally flocculants are added quantitatively or regularly, and the dosage cannot be generated according to the current flow and velocity of sewage. Variety
