[0025] By discharging sewage into the treatment tank 1, the aeration pump 7 discharges air or oxygen into the sewage, and the gas forms bubbles in the sewage and moves upward. The servo motor 8 drives the transmission shaft 4 to rotate the first blade 5 and the second blade 6. The second blade 6 continuously crushes the bubbles, thereby improving the mixing effect of the gas and sewage and the oxidation effect of the sewage. The large bubbles are blocked by the mesh plate 3, and the first blade 5 rotates on the bottom surface of the mesh plate 3 to crush the large bubbles on the bottom surface of the mesh plate 3, thereby further improving the mixing effect of the gas and sewage and the oxidation effect of the sewage.

A water pipe 201 is provided inside the mounting hole. A plurality of aeration holes 202 are evenly distributed on the upper side of the aeration nozzle 2, and the plurality of water pipes 201 and the plurality of aeration holes 202 are staggered. By staggering the plurality of aeration holes 202 and the water pipes 201, the mixing effect of the sewage and the gas discharged from the aeration holes 202 is improved.

[0027] See also Figure 2 As shown, in this embodiment, multiple second blades 6 are arranged in a spiral array on the transmission shaft 4, and an exhaust valve is connected to the upper side of the treatment pool 1 to facilitate the second blade 6 to continuously crush bubbles and improve the mixing effect of gas and sewage. By arranging multiple second blades 6 in a spiral array on the transmission shaft 4, the bubble crushing effect of the second blade 6 is improved.

The circulating water pump 101 is turned on to drive the sewage circulation in the treatment tank 1, so as to facilitate the circulation and aeration of the sewage.

By setting multiple aeration holes 202 and staggered with the water pipe 201, it is convenient to improve the mixing effect of the sewage and the gas discharged from the aeration holes 202. The gas forms bubbles in the sewage and moves upward. The servo motor 8 drives the transmission shaft 4 to drive the first blade 5 and the second blade 6 to rotate. The second blade 6 continuously crushes the bubbles, thereby improving the mixing effect of the gas and sewage and the oxidation effect of the sewage. The large bubbles are blocked by the mesh plate 3, and the first blade 5 rotates on the bottom surface of the mesh plate 3 to crush the large bubbles on the bottom surface of the mesh plate 3, further improving the mixing effect of the gas and sewage and the oxidation effect of the sewage.
