[0040] The working principle of the utility model is as follows: during use, the aeration tank 1 is enclosed by multiple cover bodies 2, multiple endurance plates 4 and two sealing plates 5, making it difficult for odor particles to enter the external air, effectively protecting the environment. Oxygen-containing gas is supplied to multiple second intake pipes 13 through a delivery pipe 12. The oxygen-containing gas is evenly supplied into multiple first intake pipes 7 through multiple corrugated pipes 14 on the second intake pipes 13. The oxygen-containing gas in the first intake pipes 7 enters the corresponding membrane tube aerators 8 to aerate the sewage in the aeration tank 1. When the aeration structure needs to be repaired, first turn on the corresponding two or more motors 19. The output shafts of the motors 19 drive the corresponding second bevel gears 20 to rotate.

When installing the first intake pipes 7, first open multiple round holes in the endurance plates 4, then slide the sliding sleeves 6 through the corresponding round holes. Then, slide a buffer pad 21 over the top of the sliding sleeve 6 so that the buffer pad 21 contacts the top of the corresponding endurance plate 4. Then, thread a pressing plate 22 onto the top of the sliding sleeve 6 so that the pressing plate 22 contacts the buffer pad 21. Then, install another buffer pad 21 and pressing plate 22 at the bottom of the sliding sleeve 6 in the above method, so that the buffer pad 21 contacts the corresponding two support rods 3, and the lower pressing plate 22 presses the corresponding buffer pad 21, so that the sliding sleeve 6 is installed and fixed on the endurance plate 4. Then, slide the first intake pipe 7 through the sliding sleeve 6, and fix the top of the first intake pipe 7 on the corresponding cross bar 9. Then, install other sliding sleeves 6 and first intake pipes 7 in the above method in sequence.
