Municipal Sewage Treatment System

technical field

The invention relates to the field of sewage treatment, in particular to a municipal sewage treatment system.

Background technique

Domestic sewage, industrial wastewater and runoff sewage in urban areas are the three major types of municipal sewage. Generally, they are collected by urban pipes and channels and should be treated by urban sewage treatment plants before being discharged into water bodies. Urban sewage contains a large amount of organic matter and bacteria. , virus, the treatment of urban sewage involves many aspects, and it is necessary to comprehensively plan the sewer system, the location and treatment process of the sewage treatment plant, and the utilization and discharge requirements of the treated sewage.

In the prior art, the Chinese patent with the authorization announcement number CN204588727U that can be referred to, which discloses that the present invention relates to a high-efficiency sieve-tube grille decontamination machine. It includes a sieve cylinder grille, the sieve cylinder grille is installed in the box through a rotating spindle, a drive device is installed on the right side of the box to drive the rotating spindle to rotate, the sieve cylinder grille has a gap of 0.5mm~3mm, and the screen The radial gap of the cylinder grille is narrow outside and wide at the inside. The front end of the screen cylinder grille is provided with a cleaning brush to fit with its circumferential surface. The front end of the box is provided with a bracket. The cleaning brush is installed on the bracket through a rotating shaft. There is a water inlet, a drainage outlet is arranged at the lower end of the middle part of the box body, mounting feet are respectively arranged at the four corners of the box body, and an overflow channel is arranged in the box body to connect with the drainage outlet. The present invention has a simple structure. By adopting a sieve cylinder grille with a radial outer narrow and an inner width gap of 0.5 mm to 3 mm, the fine impurities below 3 mm cannot be separated, and the amount of water passing through is large, and the debris on the outer surface of the sieve cylinder grille is easy to clean.
