Subsequently, the fan 4 passes air into the air supply pipe 3, and then the air is passed into the sewage in the outer shell 1 through the exhaust pipe 2. Then the motor 6 is started. The motor 6 drives the gear 1 7 fixedly connected to the output end. At this time, the gear 1 7 drives the meshing gear 2 8, and at the same time, the gear 2 8 drives the stirring rod 9 to move. The device stirs the sewage while aerating. By stirring the sewage, the suspended matter is kept evenly suspended, which helps to maintain a uniform temperature and oxygen distribution in the aerobic pool and improve the suspension of the suspended matter.

[0023] Reference Figure 1 - Figure 3The fixing assembly includes a fixing block 13 and a fixing bolt 14, one side of the outer wall of the fixing block 13 is fixedly connected to the outer wall of the housing 1, and the outer wall of the fixing bolt 14 is threadedly connected to the inside of the fixing block 13;

[0024] Specifically, when it is necessary to clean the sludge precipitated in the sewage, first turn the fixing bolt 14, then disassemble the fixing block 2 13, and then control the hydraulic cylinder 16 to descend to drive the tank bottom 15 to descend, and then clean the sludge. As time goes by, sludge will accumulate in the aerobic tank, resulting in a reduction in the effective volume. Cleaning the sludge can restore the designed volume of the aerobic tank and ensure the normal operation and processing capacity of the treatment system.

[0026] Specifically, when the aerobic tank for rural domestic sewage treatment needs to be used to check the internal conditions of the aerobic tank, the fixing bolt 23 can be turned, and then the handle 12 can be moved, and then the handle 12 drives the cover 11 to move, and the aeration conditions inside the aerobic tank can be checked. The pretreatment unit 20, the aerobic tank and the sedimentation tank 21 are all fixed on the base 22, which can prevent corrosion by microorganisms in the soil.

[0027] Working principle: When using the aerobic pool for rural domestic sewage treatment, first start the fan 4, then the fan 4 passes air into the shell 1 through the air supply pipe 3, then start the motor 6, and then the motor 6 drives the gear 1 7 fixedly connected to the output end to move. At this time, the gear 1 7 is forced to drive the meshing gear 2 8 to rotate, and at the same time, the gear 2 8 drives the stirring rod 9 fixedly connected to the outer wall to start rotating, and then the sewage is passed into the pretreatment unit 20 for pretreatment, and then passed into the shell 1 through the pipeline 19 to start aeration. After the aeration is completed, it is passed into the sedimentation tank 21 through the pipeline 19. When the shell 1 is used for a long time, sludge will be generated inside. When the sludge needs to be cleaned, the fixing bolt 14 is rotated and the fixing block 2 13 is disassembled, and then the hydraulic cylinder 16 is started. The hydraulic cylinder 16 drives the tank bottom 15 fixedly connected to the output end to descend, and then the sludge can be cleaned.
