The water seal tube 4 is installed inside the aeration device body 1 through a positioning structure. The air inlet 101 of the aeration device body 1 is connected with the microporous aeration tube 2. The microporous aeration tube 2 is fixed to the bottom of the aeration device body 1 through an aeration tube clamp 3. The inner wall of the aeration device body 1 is provided with a plurality of stiffening ribs 10. The air distributor 5 is provided at the air outlet 104 of the aeration device body 1.

[0033] When the utility model is in use, gas enters the microporous aeration tube 2 through the air inlet 101 of the aeration device body 1, and the microporous aeration tube 2 performs continuous and uniform micro-aeration. The aerated gas enters the top of the air cavity 103 of the aeration device body 1 and accumulates. When the accumulated height of the gas is lower than the tube height of the aeration device body 1, a passage is formed between the gas inside the aeration device body 1 and the outside of the aeration device body 1. The gas instantly forms a positive pressure through the water seal tube 4 in the aeration device body 1, and performs large aeration to the outside. The aerated gas is discharged through the holes uniformly distributed in rotation on the gas distribution plate 5 above the aeration device body 1, so as to achieve aeration.
