[0002] A deep aeration device for sewage treatment is mainly used to provide sufficient oxygen supply in the sewage treatment process, promote biodegradation reaction, and thus accelerate the removal of pollutants. The deep aeration device for sewage treatment is an efficient and energy-saving sewage treatment equipment, suitable for urban sewage treatment plants, industrial wastewater treatment plants and other places that require deep sewage treatment;

[0003] The deep aeration device for sewage treatment in the prior art can increase the water-oxygen contact area by lifting the water in the sewage pool, and the aeration device can more effectively transfer oxygen from the air to the water, thereby accelerating the speed at which oxygen dissolves into the water; however,

[0004] First, since the sewage pool is exposed to the outdoor environment, there may be garbage such as plastic bags and dead leaves in the sewage pool. During the stirring process of the water surface, the plastic bags are easily entangled on the stirring rod. The plastic bags and other garbage entangled on the stirring rod will increase the resistance of the stirring rod, making the stirring process more difficult, thereby reducing the stirring efficiency. The existing technology lacks a cleaning function for the stirring rod;

[0005] 2. When the coagulant is stored or used, it is affected by the humid environment. The chemical substances inside it may react with water molecules, resulting in agglomeration. Putting the agglomerated coagulant into sewage will reduce the efficiency of sewage treatment.

[0006] Therefore, a deep aeration device for sewage treatment is proposed. Utility Model Content
