Abstract

The invention discloses an aerobic pool capable of preventing sludge accumulation. An aerobic pool body is included, a water inlet pipe is arranged on the side wall of the aerobic pool body, the waterinlet pipe is communicated with the aerobic pool body, a water collecting chamber is formed in the aerobic pool body, a water inlet is formed in the upper portion of the water collecting chamber 3, the water inlet is communicated with the aerobic pool body, a stirring device is arranged in the water collecting chamber, a rotating brush aerator is arranged in the aerobic pool body, an aerating device is arranged at the bottom of the aerobic pool, the aerating device comprises an air inlet, an aerating pipe and aerating nozzles, the air inlet is communicated with outer air, multiple aerating nozzles are arranged on the aerating pipe, and the aerating nozzles oblique towards the water inlet. By means of the aerobic pool, the problem of sludge bulking caused by the ageing of sludge when aerobic processing is conducted on sewage water in the aerobic pool is solved.

Description

technical field [0001] The invention relates to sewage treatment, in particular to an aerobic pool for preventing sludge accumulation. Background technique [0002] Aerobic treatment is a process that relies on the biochemical action of aerobic bacteria and facultative anaerobic bacteria to complete the treatment process. The mechanism of action is to degrade organic matter mainly by aerobic microorganisms under the premise of providing free oxygen. The sewage is usually It is carried out in the aerobic tank. During the treatment process, due to the aging of the sludge, the dissolved oxygen will be insufficient, which will cause the phenomenon of sludge swelling in the aerobic tank; [0003] Sludge bulking is a manifestation of the lightening, swelling, and deterioration of the sedimentation performance of the activated sludge, which makes it impossible to carry out normal sewage separation in the secondary sedimentation tank in the later stage, eventually leading to sludge ...
