Through the arrangement of the aeration head 32, the gas can be discharged from the aeration head 32 through the top outlet 323 and multiple side outlets 322 after entering the aeration head 32. At this time, the gas has multiple paths, and aeration is formed in the multiple paths. , which in turn can increase the contact area between the gas and the water body after it is discharged, ensuring the degree of mixing between the gas and the water body. The directions of the multiple side outlets 322 are at a certain angle. During the aeration process of the multiple side outlets 322, the aeration head 32 can be rotated. During the rotation process, the aeration head 32 discharged from the multiple side outlets 322 can be further increased. The degree of mixing of gas and water.

The above-described embodiments describe the technical solutions of the present invention in detail. It should be understood that the above-mentioned are only specific embodiments of the present invention and are not intended to limit the present invention. Any work done within the scope of the principles of the present invention Any modifications, additions or similar substitutions shall be included in the protection scope of the present invention.
