Sterilizing and air dissolving device for sewage treatment

Abstract

The invention discloses a sterilizing and dissolving device for sewage treatment, which comprises a device body, the device body is mainly composed of a sewage inlet, a sewage outlet, an air compressor and an aeration plate; the sewage inlet extends to the device body A universal joint is connected inside, and the bottom of the universal joint is connected with a sprinkler head. The inside of the sprinkler head is provided with a plurality of spiral drainage grooves. The bottom of the device body is fixedly equipped with a first overflow groove. A second overflow groove is provided, and a third overflow groove is arranged in the second overflow groove; a rotating shaft is vertically arranged in the body of the device, and the first overflow groove, the second overflow groove and the third overflow groove There is a sliding plate in the overflow tank, and the first fine hole is set on the sliding plate. The device does not need external power to make the nozzle rotate, which increases the amount of dissolved air and saves energy. The sewage in the device is divided into water curtain and fountain. This form is in contact with the air in the device, which greatly improves the air-dissolving efficiency of the sewage and facilitates the subsequent sewage treatment.

Description

technical field [0001] The invention belongs to the field of environmental protection sewage treatment, and in particular relates to a sterilizing and gas-dissolving device for sewage treatment. Background technique [0002] With the rapid development of my country's economy and the acceleration of the industrialization process, my country's GDP growth is relatively rapid, but the ensuing environmental pollution problems are also relatively serious, especially the situation of water pollution in my country is particularly serious. [0003] Water is a natural resource that human beings rely on for survival. People produce a large amount of sewage every day. If the sewage is not treated effectively, it will easily cause water environment pollution. [0004] In sewage treatment, the dissolved air treatment of sewage is a particularly important procedure in sewage treatment. At present, the dissolved air treatment of sewage in my country mainly adopts the form of aeration, and t...

Problems solved by technology

[0003] Water is a natural resource that human beings rely on for survival. Every day, people produce a large amount of sewage. If the sewage is not treated effectively, it will easily cause water pollution.

[0004] In sewage treatment, the dissolved air treatment of sewage is a particularly important procedure in sewage treatment. At present, the dissolved air treatment of sewage in my country mainly adopts the form of aeration, and the air is passed into the sewage, and the air is dissolved in the sewage, but the air is in The residence time in the sewage is short, the amount of dissolved air is not high, the efficiency of dissolved air is low, and it is difficult to maintain the subsequent sewage treatment to achieve the ideal treatment effect
