After the aquaculture tail water enters the water inlet channel 112, it is first filtered by the filter grid 105 to intercept large impurities, and then blocked by the water retaining plate 113, flowing downward first and then upward, so that some impurities are settled in the first sewage collection tank 116, and then pass through the U-shaped sedimentation wall 114, and the flow direction is also first downward and then upward. Some impurities are further settled in the U-shaped sedimentation wall 114 and fall into the second sewage collection tank 117, and finally flow through the filler filter structure 115, and are adsorbed and purified before being discharged.
