[0002] With the continuous growth of people's demand for aquatic products, the output of aquaculture has increased year by year. However, with the expansion of aquaculture scale, farms will produce a large amount of aquaculture tailwater. Pollutants such as leftover bait, feces and other metabolites in the tailwater increase the nutrient load of adjacent waters. The discharge of pollutants from aquaculture tailwater has aggravated the eutrophication level of receiving water bodies to a certain extent, thereby destroying the ecological environment of the water bodies. In addition, water environmental pollution has also restricted the healthy and sustainable development of aquaculture. In response to this, the state has increasingly strengthened supervision over aquaculture emissions, and aquaculture carried out in some lakes, reservoirs and other places has been banned or restricted. The issue of compliance with the discharge standards of aquaculture tailwater has also attracted great attention from aquaculture practitioners.

[0003] At present, the common aquaculture effluent treatment technology is chemical treatment, that is, adding chemicals to the sewage. Chemical methods for sewage treatment require the use of a large amount of chemicals and equipment, and the construction and operating costs are relatively high. It is difficult for ordinary farmers to bear the high sewage construction and operating costs, and chemicals will also have a negative impact on the environment. Utility Model Content

The water pump 4 is arranged in a movable and extractable form and is not fixed to the device body 2, so that the water pump 4 can be taken out for cleaning and maintenance later; negative pressure is generated by the water pump 4, so that the sewage flows from the outside of the device body 2 through the filling area and the circulation area 3 in turn. When the sewage flows through the filling area, the sewage is purified by the filling area. Specifically, the filling area includes a ceramic ring arranged from the inside to the outside.
