Urban sewage treatment device capable of effectively dispersing sludge

Abstract

The invention discloses an urban sewage treatment device capable of effectively dispersing sludge, which comprises a box body, a water inlet pipe arranged at the top of the box body, a stirring mechanism arranged in the water inlet pipe, and a filtering mechanism arranged at the top in the box body. Meanwhile, large sludge in the sewage can be crushed, so that a water inlet pipe is prevented from being blocked; through the use of a belt pulley I, a belt, a belt pulley II, a transmission shaft, a transmission column, a connecting column, a pull rod, a scraping plate, a push rod, a filter box door and a first spring, sewage can be better filtered, and meanwhile, sludge is prevented from blocking a filter plate I; through use of blades, a connecting shaft, a disc, a transmission rod, a connecting rod, a baffle plate, a second spring and a sealing plate, the sewage treatment device can intermittently apply pesticides into sewage and stir the sewage, so that the sewage and the pesticides are mixed more uniformly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban sewage treatment device that can effectively disperse sludge. Background technique [0002] Sewage, usually refers to the effluent from living and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater, initial rainwater and water samples containing hazardous chemicals or uncertain hazardous properties. The main pollutants in sewage are pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. With the continuous development and progress of society, there are more and more domestic sewage and industrial wastewater. In order to avoid environmental pollution caused by the direct discharge of sewage, sewage is usually treated by sewage treatment devices. [0003] When the existing sewage treatment device treats sewage, since there are many sundries in the sewage, especially the ...

AI Technical Summary

Problems solved by technology

[0003] When the existing sewage treatment device treats sewage, because there are many sundries in the sewage, especially sticky sludge and other sundries will block the treatment pipeline during the sewage treatment process, the sewage treatment pipeline needs to be dredged in time, and in During the filtration process, the filter plate will be frequently blocked, and the filter plate needs to be cleaned frequently, which reduces the overall processing speed, and requires a large labor cost, which is very inconvenient
