Sewage processing system

Abstract

The invention discloses a sewage processing system. The sewage processing system comprises an anaerobic pond, an aerobic tank, a flocculation basin, a filtering tank, and a disinfecting tank which arecommunicated through pipelines successively; a slag water separator is arranged at a water inlet of the anaerobic pond; an anaerobic biological rotating disc is arranged in the anaerobic pond; an aerobic biological disc is arranged in the aerobic tank; an adhesion foundation bed of the anaerobic biological rotating disc and an adhesion foundation bed of the aerobic biological rotating disc comprise a plurality of fan-shaped discs which are arrangedin annular arrays and are connected successively; a triangular grid structure is adopted by the fan-shaped discs; and the adjacent triangular holecross sections of the triangular grid structures are provided with projections. In applications, sewage is delivered through the slag water separator, the anaerobic pond, the aerobic tank, the flocculation basin, the filtering tank, and the disinfecting tank successively for processing; the processing technology is reasonable and effective; the triangular grid structures are adopted by the anaerobic biological rotating disc and the aerobic biological rotating disc, so that the specific surface area is larger, higher sewage treatment efficiency and better effect are achieved, and the dischargesewage is capable of reaching standards.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] In industrial production and other processes, a large amount of sewage is usually generated. If such sewage is not treated and discharged directly, it will not only cause serious pollution to the environment, but also affect human health. [0003] The biological turntable is a biofilm sewage treatment technology, which installs the disks on the rotating shaft at intervals, and immerses them in the sewage in the treatment tank for rotation, so that the sewage is treated by contacting various bacteria attached to the disks. . [0004] However, at present, the domestic biological turntable has a small specific surface area and poor film-hanging performance, which is likely to cause a large area of ​​film removal, so that the sewage in the sewage treatment tank has little contact with the bacteria attached to the disk...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the specific surface area of ​​the domestic biological turntable is small and the film-hanging performance is poor, which is easy to cause large-scale defilming, so that the sewage in the sewage treatment tank has little contact with the bacteria attached to the disk, and the sewage treatment efficiency is low. treatment cost; and using the biological turntable alone as a sewage treatment device cannot treat the sewage up to the standard, so how to improve the sewage treatment efficiency and effect of the biological turntable and make the sewage treatment up to the standard is a technical problem that those skilled in the art need to solve at present
