[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. During the sewage treatment process, in order to maintain the life activities of microorganisms that purify sewage, it is necessary to ensure that there is a certain amount of dissolved oxygen in the water. Therefore, aerators are needed in sewage treatment. Aerators continuously pump air into the water. Aerators are key equipment for oxygen supply in the sewage treatment process.

[0003] According to an aerator for sewage treatment disclosed in application number CN202223173862.3, the technical solution thereof can effectively improve the bubble mixing degree of the aerator through the arrangement of stirring blades and aeration rings, and quickly spread the bubbles throughout the aeration tank, and form a first trumpet-shaped mixing enhancement area through the coordinated arrangement of a trumpet-shaped mixing enhancement cover and a spherical auxiliary mixing block, and form a high flow rate area at the constriction position of the first trumpet-shaped mixing enhancement area under the action of the stirring blades lifting the water flow upward, so that the bubbles exposed by the aeration ring located at the position are quickly mixed with the sewage passing through the high flow rate area, and The gas and liquid mixture are fully mixed with each other for the first time in the first mixing zone; at the same time, the gas and liquid mixture mixed for the first time is mixed again under the action of the stirring blades in the second mixing zone formed at the inner contraction position of the trumpet-shaped mixing enhancement cover, which further effectively improves the mixing degree of bubbles and sewage.
