The super-magnetic rotary drum 21 is magnetic and can adsorb alum blossom magnetic seed flocs in the sewage in the separation tank 24 in the rotating process, so that the sludge is rapidly gathered on the surface of the magnetic rotary disc.
Preferably, the V-shaped groove 231 is disposed outside the brush 22 such that the material brushed by the brush 22 enters the V-shaped groove 231, the cross section of the V-shaped groove 231 is V-shaped, the discharge-assisting jet nozzle 232 is disposed on the upper side of the groove surface of the V-shaped groove 231, and the nozzle direction points to the bottom of the V-shaped groove 231 along the groove surface.
