[0025] The working principle and beneficial technical effects of the above technical solution are as follows: sewage enters the pre-sedimentation adjustment zone 4 from the sewage pipe 8 for sedimentation, and heavy lumps sink. When the liquid level reaches the height of the first connecting hole 12, the supernatant flows to the aerobic zone 5 through the first connecting hole 12. Aerobic microorganisms are placed in the aerobic zone 5. Aerobic microorganisms grow and reproduce in an oxygen-sufficient environment.

A recycling water pump 15 is provided in the clean water area 7, and the output end is connected to the water outlet pipe 9. When the liquid level in the clean water area reaches a certain height, the recycling water pump 15 will start to extract water from the clean water area to avoid overfilling the clean water area 7.

[0028] The aeration assembly includes: a cylinder 24, a cylinder 24 is arranged on the right side of the inclined chute body 23, the cylinder 24 is connected to the inner wall of the box body 16, a reciprocating piston 25 is arranged in the cylinder 24, one end of the push rod 26 is connected to the piston 25, the other end of the push rod 26 extends out of the cylinder 24 and is connected to the slide column 27, the slide column 27 slides in the arc chute body 22 and the inclined chute body 23, an oxygen tank 28 is arranged above the cylinder 24, the oxygen tank 28 is connected to the inner wall of the box body 16, one end of the first gas pipe 29 is connected to the gas outlet of the oxygen tank 28, the first gas pipe 29 is provided with a first gas delivery check valve 30, and the other end of the first gas pipe 29 is connected to the left side of the cylinder 24. The first air supply pipe 31 is connected to the left end of the cylinder 24, a first air supply check valve 32 is provided on the first air supply pipe 31, the other end of the first air supply pipe 31 is connected to the sleeve 33, the sleeve 33 is connected to the end of the rotating pipe 21 away from the aeration pipe 10 and is rotatably connected, one end of the second air supply pipe 34 is connected to the air outlet of the oxygen tank 28, a second air supply check valve 35 is provided on the second air supply pipe 34, the other end of the second air supply pipe 34 is connected to the right end of the cylinder 24, one end of the second air supply pipe 36 is connected to the right end of the cylinder 24, a second air supply check valve 37 is provided on the second air supply pipe 36, and the other end of the second air supply pipe 36 is connected to the sleeve 33.

[0029] The working principle and beneficial technical effects of the above technical solution are as follows: the motor 17 is started to drive the crank 18 to rotate, and the crank 18 drives the connecting rod 19 to move. The crank 18, the connecting rod 19 and the rocker 20 form a crank-rocker mechanism, which drives the rocker 20 to swing left and right. The rocker 20 drives the rotating tube 21 and the aeration tube 10 to rotate alternately forward and reverse around the axis of the rotating tube 21, so as to fully stir the microorganisms and sewage. At the same time, the rocker 20 drives the arc-shaped slide trough body 22 and the inclined slide trough body 23 to move back and forth left and right, so that the slide column 27 slides in the arc-shaped slide trough body 22 and the inclined slide trough body 23. When the slide column 27 slides in the arc-shaped slide trough body 22, the slide column 27 remains stationary. When the slide column 27 slides in the inclined slide trough body 23 on the right, the slide column 27 moves back and forth to the left once. When the slide column 27 moves back and forth to the left once, the slide column 27 moves back and forth to the left once. When the column 27 slides in the inclined slide groove body 23 on the left, the slide column 27 moves back and forth to the right once, which drives the push rod 26 and the piston 25 to move accordingly. The piston 25 will stop at the middle position in the cylinder 24, then move back and forth to the left once, then stop at the middle position, and then move back and forth to the right once, and then return to the middle position of the cylinder 24 to stop, thereby continuously circulating, so that the first air supply pipe 29 and the second air supply pipe 34 alternately transport oxygen from the oxygen tank 28, and then the first air supply pipe 31 and the second air supply pipe 36 alternately supply air to the rotating pipe 21. When the piston 25 stops at the middle position of the cylinder, the air supply stops, so that the aeration hole 11 intermittently supplies air, so that the microorganisms are fully in contact with the oxygen, the sewage treatment efficiency is improved, and the waste of oxygen is reduced.

[0030] In one embodiment, Figure 1-4As shown, the push rod 26 passes through the fixed block 38 and is slidably connected with the fixed block 38. The fixed block 38 is connected to the inner wall of the box body 16. The fixed block 38 provides support so that the push rod 26 moves left and right more smoothly.
