[0020] like Figures 1 to 5 As shown, this utility model relates to an aeration device for sewage treatment, including an air supply pipe 1, a connecting pipe 2, an air delivery pipe 3, a connecting assembly 4, and an aeration assembly 5. The aeration assembly 5 is arranged below the air delivery pipe 3 through the connecting assembly 4, and the connecting assembly 4 is arranged below the air supply pipe 1 through the connecting pipe 2, with the connecting pipe 2 arranged on one side of the air supply pipe 1. The connecting assembly 4 includes an air outlet pipe 401, a limiting plate 402, and an air outlet 403. The air outlet pipe 401 is fixedly connected to the lower part of the air delivery pipe 3, the limiting plate 402 is fixedly disposed on the outer circumferential wall of the air outlet pipe 401, and the air outlet 403 is opened on the outer circumferential wall of the air outlet pipe 401, and the air outlet 403 is located between the limiting plates 402. It is worth noting that when gas is delivered to the outlet hole 403 on the outlet pipe 401 via the air supply pipe 1, the limiting plate 402 on the outlet pipe 401 is limited by the fixing plate 502 at both ends of the aerator 501, thus enabling the aerator 501 to rotate along the surface of the outlet pipe 401. When gas is delivered to the aerator 501 from the outlet hole 403, it passes through the paddle blades 504 inside the aerator 501. When the gas enters the aerator 501, it drives the paddle blades 504 to rotate, realizing the rotating function of the aerator 501. The aerator 501 is now rotated to solve the problem of sediment buildup in the wastewater tank causing blockage on its surface. Furthermore, the L-shaped aeration holes 505 on the aerator 501, when in use, force the sediment within them to be ejected during rotation and aeration. This effectively removes the sediment from the aeration holes 505, further resolving the issue of poor aeration efficiency in the wastewater tank due to sediment blockage of the aeration holes 505.
[0021] In embodiments of this utility model, such as Figure 3 As shown, the aeration assembly 5 includes an aerator 501, a fixing disc 502, a groove 503, paddle blades 504, and aeration holes 505. The aerator 501 is rotatably connected to the outer circumferential wall of the air outlet pipe 401. Two fixing discs 502 are respectively fixedly connected to both ends of the aerator 501. Two grooves 503 are respectively formed inside the circumference of the two fixing discs 502, and the two grooves 503 are rotatably fitted onto the outer circumferential walls of the two limiting discs 402. It is worth noting that, as... Figure 3 As shown, the aerator 501 can rotate along the air outlet pipe 401 by limiting the limiting disc 402 on the air outlet pipe 401 by the fixing disc 502 set at both ends of the aerator 501.

[0025] As another embodiment of the utility model, twelve gas supply pipes 3 are fixedly communicated at the bottom of the two connecting pipes 2, and the axis of the twelve gas supply pipes 3 forms a vertical right angle with the axis of the two connecting pipes 2.
[0026] Working principle: the embodiment provides a sewage treatment aeration device, in use, the aerator 501 is fixed in the bottom of the sewage tank, the air blower is closely communicated with the air supply pipe 1, the gas is sent to the air supply pipe 1 by the air blower, then the gas is sent to the connecting pipe 2 from the air supply pipe 1, the connecting pipe 2 sends the gas to the air supply pipe 3, then the air supply pipe 3 discharges the gas from the air outlet hole 403 on the air outlet pipe 401, when the gas is discharged from the air outlet hole 403, since the fixing disc 502 on the aerator 501 is sleeved on the limiting disc 402 on the air outlet pipe 401, the gas enters the inside of the aerator 501 and drives the paddle blade 504 to rotate, the aerator 501 is rotated on the surface of the air outlet pipe 401, the aerator 501 is avoided to be blocked by the precipitate on the surface, then when the aerator 501 rotates, the gas is discharged from the aeration hole 505 to the sewage tank and treated to the precipitate, when the aerator 501 is not used, the precipitate enters the aeration hole 505, since the hole is L-shaped, the precipitate cannot enter the aerator 501, when the precipitate enters the aeration hole 505, only the aerator 501 is started, the aerator 501 is rotated by the paddle blade 504 and the gas is discharged from the inside to the outside from the aeration hole 505, and the precipitate in the aeration hole 505 is thrown out.
