When normal aeration is required, the micropore aeration control valve 601 is opened, and air enters the micropore aeration air distribution pipe 210 through the micropore aeration air inlet pipe 211. The air in the microporous aeration air distribution pipe 210 is only allowed to enter the microporous aeration pipe 230, and the air is uniformly aerated in the liquid in the tank body through the air holes with smaller pore diameters, namely micropores, of the microporous aeration pipe 230.

As shown in fig. 4-6, the microporous aeration pipe 230 is connected to the microporous aeration distribution pipe 210 by a first threaded joint 231 and to the coarse aeration distribution pipe 220 by a second threaded joint 232.
