Turntable type dynamic sewage fermentation tank

Abstract

The invention discloses a turntable type dynamic sewage fermentation tank, which comprises a main body of the fermentation tank. A fermentation room is arranged in the main body of the fermentation tank. The fermentation room is provided with a driving motor and a dynamic fermentation bin. The end of the output shaft is connected to the bevel gear set that rotates in different directions, and is driven by the bevel gear set and the bending rotating part; the first crescent plate on the side wall and the upper air intake mechanism are also installed in the dynamic fermentation chamber; the bending and rotating The part includes a waist-shaped rotating ring integrally formed with it, and a first piston device and a second crescent plate are arranged on the waist-shaped rotating ring, and the first piston device and the first crescent plate are rollingly connected, and the second crescent plate and the air intake mechanism slide Connection; the single drive motor of the present invention continuously increases the dissolved oxygen content in the dynamic fermentation chamber, and is always in the state of automatic oxygen supply, thus making the biological fermentation process in the dynamic fermentation chamber more efficient.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a turntable type dynamic sewage fermentation tank. Background technique [0002] The biological turntable process is an artificial enhancement of sewage irrigation and land treatment. This treatment method allows micro-animals such as bacteria and fungi and protozoa to grow and breed on the filler carrier of the biological turntable to form a film-like biological sludge-- - Biofilms. After primary treatment in the sedimentation tank, the sewage is in contact with the biofilm, and the microorganisms on the biofilm absorb the organic pollutants in the sewage as nutrients to purify the sewage. In the pneumatic biological turntable, the dissolved oxygen required for microbial metabolism is supplied through the aeration tube located on the lower side of the biological turntable. The surface of the turntable is covered with an air cover, and the compressed air released from the aeration ...

AI Technical Summary

Problems solved by technology

[0003] As the country pays more and more attention to sewage treatment in rural areas and residential areas, due to geographical problems, rural areas and residential areas are far away from the sewage treatment center, and the cost of laying corresponding sewage sewage pipelines is relatively high. Therefore, if the sewage treatment can be carried out nearby, it can effectively save capital. , Therefore, in the process of sewage treatment, a sewage fermentation tank is produced; however, the existing sewage fermentation tank, the fermentation process is slow, and the sewage fermentation does not carry out relatively simple sewage purification treatment

[0004] Most of the biological turntables use aerobic bacteria to purify sewage, so that sewage can be biologically fermented in a closed aerobic environment; but one of the factors that determine the rate of biological fermentation is the content of dissolved oxygen in sewage and indoor oxygen content, and the consumption of aerobic bacteria After oxygenation, oxygen needs to be incorporated into the sealed fermentation tank, and oxygen supply equipment needs to be connected, which takes a lot of time and effort
