Along with the continuous circulation of water flow, sludge impurities and superconducting magnetic powder in the water body can be gradually reduced, so that the circulating filtration is realized, and the sewage treatment equipment is facilitated to be simplified. At this time, the water pump 6 is used for supplementing water, and after the water body is gradually cleaned, the second cavity 102 is emptied through the fourth pipe 34.
