AI Technical Summary

Technical Problem

When the existing sewage treatment aeration tank treats sewage with more oil and fat, more foam will be generated during the decomposition process, resulting in the sewage surface being less likely to come into contact with the air, affecting the degradation effect, and the mixing contact efficiency is low.

Method used

A sewage treatment aeration tank was designed to add movable propeller and foam collection functions. By rotating above the pool, the propeller improves the mixing efficiency of activated sludge and sewage and increases the oxygen content. The foam collection function drives the collection baffle to move on the sewage surface through a cleaning rack, collecting and pushing the foam to the edge of the pool.

Benefits of technology

The sewage degradation efficiency is improved, and through sufficient mixing and increasing the oxygen content, aerobic microorganisms can decompose organic pollutants more quickly. At the same time, by effectively collecting foam, the sewage surface can be fully in contact with the air, further improving the degradation effect.

Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment devices, and more specifically, particularly relates to a sewage treatment aeration tank. Background Art

[0002] The sewage treatment aeration tank uses the activated sludge method to treat sewage. Its main function is to provide a certain sewage retention time, provide sufficient oxygen for the aerobic microorganisms in the activated sludge, and ensure that the sewage and the activated sludge are fully in contact and mixed, thereby effectively degrading the organic pollutants in the sewage. The existing sewage treatment aeration tank is generally composed of a tank body, a gas pipeline and a water inlet.

[0003] For example, the invention application with the existing application number 202010278368.X discloses a sewage treatment aeration tank, including a tank body, a mounting plate, a rotating motor, a first gear, a first bevel gear, a mounting hole, a first sleeve, an annular slide groove, an annular slider, a second gear, a first rotating shaft, a second bevel gear, an induced draft box, a fan blade, an air inlet, a second sleeve, a second rotating shaft, a third bevel gear, a fourth bevel gear, a stirring blade, an air outlet, a filter screen, a water inlet, a water outlet and a protective cover. A mounting plate is welded on the outer wall of the top middle part of the tank body, and a mounting hole is provided through the center of the outer wall of the top end of the mounting plate. A first sleeve is inserted into the inside of the mounting hole, and a second gear is fixedly installed on the outer wall of the top end of the first sleeve. Driven by a rotating motor, the fan blade can introduce air into the tank, and can also enable the stirring blade to rotate and revolve in the tank, thereby improving the contact between the activated sludge and the air, making the stirring more sufficient, and improving the work efficiency.

[0004] Based on the above, the existing sewage treatment aeration tank is generally composed of a tank body, a gas pipeline and a water inlet. When in use, the sewage enters the tank body through the water inlet and contacts with the activated sludge in the tank body, so that the aerobic microorganisms in the activated sludge decompose the organic pollutants in the sewage. The gas pipeline keeps the activated sludge full of oxygen to keep the aerobic microorganisms active. When the sewage contains more oil, more foam will be produced during the decomposition process, making it difficult for the sewage surface to contact with the air, affecting the degradation effect. When oxygen is transported by the blower, the sewage and the activated sludge are contacted and mixed, and the sludge is stirred less, resulting in lower mixing contact efficiency. Utility Model Content

[0005] In order to solve the above technical problems at least to a certain extent, the utility model provides a sewage treatment aeration tank.
