[0001] The utility model relates to the technical field of sewage treatment, in particular to an aquaculture sewage treatment device based on water circulation. Background Technique

[0002] The aquaculture sewage treatment device based on water circulation is a device specifically used for treating sewage generated in the aquaculture process, and is widely used in various aquaculture scenarios. For example, in the aquaculture of shrimps, fish, etc., by using this device, harmful substances in the aquaculture wastewater can be effectively removed, the water quality can be improved, the growth and reproduction of aquaculture organisms can be promoted. At the same time, this device can also realize the recycling of water resources, reduce the aquaculture cost and reduce the environmental pollution.

[0003] During the use of the existing aquaculture sewage treatment device, generally, the sewage is filtered and pretreated through a filtering structure. However, after a long time of use, the filtering structure needs to be replaced. When replacing the filtering structure, the entire filtering process needs to be stopped, resulting in a reduction in the filtering efficiency. At the same time, when the sewage is precipitated, part of the sludge is easily attached to the side wall of the sedimentation tank, and the long-term accumulation causes corrosion of the side wall, and at the same time reduces the volume of the sedimentation tank, resulting in a reduction in the sedimentation efficiency. Content of the Utility Model
