When the first aeration tank 21 is blocked by foreign matter, the second aeration tank 22 will continue to aerate the MBR membrane. At the same time, since the number of holes in the first aeration tank 21 and the second aeration tank 22 are different, when one of them is blocked, the bubbles can be observed to determine whether it is blocked.

[0028] In the above scheme, the cleaning box 1 is sealed by the cover body on the cleaning box 1, the pulling piece 13 is fixed by the groove 12 on the cover plate 11, the MBR membrane is fixed in the cleaning box 1 by the pulling piece 13 for aeration, aeration is performed by the aeration piece 17 in the cleaning box 1, the aeration piece 17 is protected by the cover body 19, and the first aeration tank 21 and the second aeration tank 22 are used to ensure that when the second aeration tank 22 is blocked, the first aeration tank 21 can also be aerated without affecting the aeration of the MBR membrane.
