The filter screens between different groups of separation tanks can be installed differently according to the types of water slag in the aquaculture wastewater. For example, the filter screens of adjacent separation tanks can be set to different mesh numbers so that the sizes of the water slag filtered are different. Thus, after the water slag is filtered, water slag of different mesh numbers can be separated in different separation tanks, improving the separation effect. The direct drive motor 201 drives the transmission rod 203 by driving the transmission ring 202. The separation structure 1 is connected to the transmission rod 203 through the perforation of the transmission block 104. The position of the separation tank is restricted by the limit ring 204. The end of the telescopic rod of the manual telescopic rod 205 is rotatably connected to the connecting plate 404 for convenient installation and disassembly of the connecting plate 404. The transmission rod 203 drives the entire separation structure 1 to rotate, so that the aquaculture wastewater introduced from the feeding structure 3 enters the introduction tank 106. Then, under the action of centrifugal force, the wastewater is preliminarily filtered under the filtration of the first filter screen 304. Thus, the wastewater in the first separation tank 101 will be secondarily filtered by the filter screen between the first separation tank 101 and the second separation tank 102. The filtered wastewater enters the second separation tank 102 for another filtration. Finally, the filtered wastewater enters the third separation tank 103.

The filtered substances in the first separation tank 101 and the second separation tank 102 are also exported by descending through the connecting plate 404. An opening and closing plate is provided at the feeding port 302 of the feeding structure 3. The wastewater introduced from the feeding port 302 flows into the introduction tank 106 through the tapered groove. The driving motor 303 drives the transmission plate 306 with the cutting net 307 through the driving rod. During the rotation of the cutting net 307, the water slag in the wastewater is broken and stirred. The top plate 301 is installed on the workbench through the fixing device. The top plate 301 and the separation structure 1 are designed as separate bodies.
