Urban sewage treatment device

Abstract

The invention provides an urban sewage treatment device and relates to the field of sewage treatment. The urban sewage treatment device comprises a body, wherein the left side of the body is fixedly connected with an aeration box communicated with the body; the inner bottom of the aeration box is fixedly connected with an aerator; the left side of the aeration box is fixedly connected with a waterinlet pipe; the right side of the body is fixedly connected with a mounting piece; the mounting piece comprises a mounting box; the inner bottom of the mounting box is fixedly connected with a storage battery; an opening/closing door is arranged on the right side of the mounting box. According to the urban sewage treatment device disclosed by the invention, due to the arrangement of a guiding inclined seat, a cleaning piece, the aerator and the aeration box, water flow is transferred in the aeration box, aeration treatment is performed by the aerator, the guiding inclined seat guides sewage to gather and drop, sludge gathered on the guiding inclined seat is cleaned by the cleaning piece, a connecting rod and a vertical plate are driven to push and scrape the sludge by utilizing movement of an electric push rod, and the concave edge is conveniently pulled back when the bottom sludge is scraped by a bottom angle support.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment device for urban sewage. Background technique [0002] Urban sewage is a general term for the sewage discharged into the urban sewage system. In the combined drainage system, it also includes production wastewater and intercepted rainwater. Urban sewage mainly includes domestic sewage and industrial sewage, which are collected by the urban drainage network and transported to sewage treatment. The discharge of urban sewage needs to be treated with harmful substances in urban sewage before it can be discharged, reducing the harm to the environment. For urban sewage treatment, it is generally necessary to settle first, and the impurities with larger particles in the sewage can be precipitated. It is convenient to carry out the next step of filtration and disinfection. However, when the existing sewage treatment equipment settles the sewage, the water is direct...

[0002] Urban sewage is a general term for the sewage discharged into the urban sewage system. In the combined drainage system, it also includes production wastewater and intercepted rainwater. Urban sewage mainly includes domestic sewage and industrial sewage, which are collected by the urban drainage network and transported to sewage treatment. The discharge of urban sewage needs to be treated with harmful substances in urban sewage before it can be discharged, reducing the harm to the environment. For urban sewage treatment, it is generally necessary to settle first, and the impurities with larger particles in the sewage can be precipitated. It is convenient for the next step of filtration and disinfection. However, when the existing sewage treatment equipment is settling sewage, the water is directly discharged after the precipitation is completed. A large amount of impurities are easy to accumulate at the bottom of the sewage treatment equipment, which is inconvenient to clean.
