Urban industrial sewage treatment system

Abstract

The invention relates to the technical field of sewage treatment, in particular to an urban industrial sewage treatment system which comprises a shell, a sewage inlet is fixedly connected to the position, close to the upper end, of the outer surface of one side of the shell, a water outlet is fixedly connected to the position, close to the upper end, of the outer surface of the other side of the shell, and a sewage outlet is fixedly connected to the outer surface of the lower end of the shell. A sewage inlet channel is fixedly connected to the position, close to the sewage inlet, of the inner wall of the shell, evenly-distributed supporting plates are fixedly connected to the positions, close to the lower end, of the inner walls of the two sides of the shell, and two sets of fixing plates are fixedly connected to the positions, located above the supporting plates, of the inner wall of the shell. According to the sewage treatment device, sewage can drive an impact block to rotate up and down when rising in the shell, so that an inclined panel is knocked, first springs are arranged on the left side and the right side of the inclined panel, and the inclined panel rotates up and down after being knocked, so that sediments on the inclined panel rotate up and down; therefore, the sliding speed of sediments on the inclined panel from the surface of the inclined panel is increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban industrial sewage treatment system. Background technique [0002] The urban industrial sewage treatment system is a treatment system that collects solid and liquid waste and prevents it from contacting the urban population and drinking water system. Sedimentation tanks are often used in sewage treatment to separate sediments and For floating matter, the inclined plate type sedimentation tank has the best treatment effect in the existing sedimentation tank. [0003] The Chinese patent discloses a self-cleaning inclined plate sedimentation tank. The patent application number is CN202020956505.6. It is a self-cleaning inclined plate sedimentation tank. At the water outlet, the bottom of the pool body is a mud collecting hopper, and the sewage pipe is connected to the bottom of the mud collecting hopper; a sloping plate group is arranged inside the pool body, and t...

AI Technical Summary

Problems solved by technology

[0004] Although the inclined plate sedimentation tank has the best treatment effect among the types of sedimentation tanks, it is easy to cause sediment accumulation, making it difficult for the sediment to slide down the slope of the inclined plate. The above-mentioned patent uses a hoist to drive the inclined plate to change the slope to realize utilization. The gravity of the sediment itself slides down on the sloping plate, but it is impossible to process the sediment while it is settling. After working for a period of time, the inclined plate sedimentation tank needs to adjust the angle of the sloping plate to clean it.
