On the one hand, the blade plate 24 drives the upper water body to transversely flow in the rotation process, so that the floating foam on the upper water body is driven to flow along with the water body, in addition, the flowing water body impacts the inner wall of the tank body 10, so that impurities in water can be prevented from adhering to the inner wall of the tank body 10, the cleaning difficulty of the tank body 10 is reduced, the water body can be caused to shake, and the foam collision is facilitated, so that the defoaming effect is achieved. On the other hand, the blade 24 can carry part of water body to separate from the water surface in the rotation process, the part of water body flows on the surface of the blade 24, so that foam in the part of water body is dispersed, collided and converged, the part of water body falls back again in the rotation process along with the blade 24 to drive the water body to fluctuate, the probability of water body collision is improved, the impact force of water body collision is increased, and the defoaming effect is improved.

Thus, the aeration gas in the aeration pipe 32 enters the cavity 34 in the aeration column 33 and then enters the aeration channel in the first aeration disc 41. Because the inner walls of the upper aeration holes 42 and the lower aeration holes 43 are provided with screw structures, aeration gas rises in a spiral shape in the aeration channel, and in addition, the upper aeration holes 42 are communicated with the lower aeration holes 43 and are eccentrically arranged to help regulate the flow speed and flow direction of the aeration gas, so that the residence time of the aeration gas in the tank 10 is prolonged, and the dissolved oxygen in wastewater is improved. After passing through the first aeration disc 41, the aeration gas enters an aeration main pipe 45 of the second aeration disc 44 and is discharged through an aeration small hole 47 on the aeration box body 46, so that the content of dissolved oxygen in the wastewater can be further improved. In addition, the aeration box body 46 is arranged to divide the aeration gas again, and the aeration holes 47 which are uniformly dispersed on the side wall of the aeration box body are matched, so that the effect of rapid dispersion of the air flow can be achieved, the path of the aeration gas is prolonged, and the oxygen dissolution rate is also improved.
The first aeration disc 41 and the second aeration disc 44 are arranged to promote the air flow rate of the straight line rising to be reduced and the air flow rate of the transverse flowing to be increased, thereby avoiding the overflow of aeration gas from the water surface in a short time, preventing the generation of large bubbles, greatly improving the utilization rate of the aeration gas and reducing noise. Aeration gas discharged through aeration assembly 30 may induce fluctuations in the body of wastewater such that sludge therein flocculates, agglomerates, and prevents equipment from clogging.
