[0002] During the breeding process of aquaculture farms, a large amount of tail water containing solid pollutants such as feces and feed particles is often generated. On the one hand, these tail water pollutants have a strong irritating odor, and on the other hand, they contain a large amount of corrosive pollutants and polluting microorganisms such as bacteria and viruses. Therefore, it is necessary to carry out efficient and convenient tail water purification treatment on the tail water generated by the breeding farm to avoid the tail water from causing serious pollution to the breeding farm and the surrounding environment of the breeding farm. A tail water treatment device for freshwater aquaculture is needed. However, in actual use, a tail water treatment device for freshwater aquaculture with a similar structure still has many defects, such as: during the operation of the tail water treatment device, the water is not filtered at the water inlet end. When the impurities in the water are directly discharged into the sedimentation tank for sedimentation, a large amount of impurities will accumulate, which increases the labor workload during the cleaning operation of the sedimentation tank. Therefore, it is necessary to design a tail water treatment device for freshwater aquaculture. Utility Model Content
