Sewage treatment device for municipal engineering

Abstract

The invention belongs to the technical field of environmental protection equipment, and discloses a sewage treatment device for municipal engineering, the sewage treatment device comprises a sewage treatment box, a sewage input pipe and an output pipe, the sewage input pipe is used for inputting sewage into a sewage treatment cavity, the sewage treatment box is internally divided into a filter cavity and an adsorption cavity from top to bottom, and a filter screen is horizontally arranged in the filtering cavity; the filter cavity is divided into a filter cavity I and a filter cavity II by the filter screen, the filter cavity I is positioned above the filter cavity II, parallel plates are arranged on and below the filter screen, the parallel plates are fixedly connected to the front and back surfaces of the filter screen through four connecting rods, and a plurality of through holes are formed in the upper surfaces of the parallel plates, and an inverted hook is arranged in each through hole. Through the filter screen, the filter cavity I, the filter cavity II, the parallel plates, the inverted hooks and the like, fiber impurities in sewage are pretreated by virtue of the inverted hooks the filter screen so that part of the fiber impurities are hooked, the filter pressure of the filter screen is reduced, and the probability that the filter screen is blocked is further reduced.

Description

technical field [0001] The present application relates to the technical field of environmental protection equipment, and more specifically, to a sewage treatment device for municipal engineering.

AI Technical Summary

Problems solved by technology

[0003] At present, during the use of sewage treatment equipment, especially when filtering the fibrous impurities in sewage, since most of the fibrous impurities are in the form of filaments, they are easy to knot and entangle with each other, which often causes the blockage of the filter screen and reduces the sewage treatment efficiency, which is not conducive to practical use.
