The domestic sewage with different concentrations is collected separately through the water collecting well, and primary filtration is carried out on the domestic sewage; then, the domestic sewage with lower concentration is conveyed into the dosing tank 101 and simultaneously the treatment agent is added into the domestic sewage; the domestic sewage enters the dosing tank 101 after being filtered by the filter plate 102, and the baffle I1011 in the dosing tank 101 prevents the domestic sewage from directly entering the filtering tank 103 through the filtering box 1021, and simultaneously prolongs the path of the domestic sewage reaching the filtering box 1021, so that the domestic sewage and the treating agent have enough reaction time; meanwhile, the motor I1014 controls the screw rod I1015 to drive the sliding seat 1056 to slide up and down along a sliding chute on the dosing tank 101, and simultaneously, a gear on one side of the stirring paddle I1051 is meshed with the rack 1013 so as to control the stirring paddle I1051 to rotate to stir the domestic sewage, a ball on the connecting rod I1055 slides along the arc-shaped plate I1012, and the connecting rod I1055 is controlled to repeatedly squeeze the spring 1053 along the connecting cylinder 1054, so that the push plate 1052 stretches out or withdraws to disturb the flow direction of the domestic sewage; Then, the domestic sewage is filtered by the filter box 1021 and enters the filter box 103 for secondary filtration, and finally, the treated water filtered by the filter box 103 is input into a next-stage treatment device through the water outlet pipe 1032; the domestic sewage with higher concentration enters the concentration tank 104 through the feed pipe 1041, is filtered by the filter tank 1043 and then contacts the ultrafiltration membrane 1042 to filter out the treated water, and the treated water filtered out by the ultrafiltration membrane 1042 is input into the next stage treatment device through the water outlet pipe 1032, so that the pollutants in the domestic sewage are concentrated; the motor II 201 controls the screw rod II 2011 to rotate, thereby controlling the sliding plate 2012 to slide out from a sliding groove at the top of the aeration tank 203, the concentrated domestic sewage enters the aeration tank 203, the treating agent is added into the aeration tank 203 through the dosing pipe 2035, the air source simultaneously introduces compressed air into the domestic sewage through the air inlet pipe 2031, the motor III 2047 controls the screw rod III 2048 to drive the connecting box 2041 and the connecting shaft 2045 to reciprocate in the aeration tank 203, the gear II 2042 is meshed with a rack at one side of the aeration tank 203, the stirring paddle II 2043 and the stirring paddle III 2046 are driven to rotate to stir the domestic sewage, The stirring paddle II 2043 can stir domestic sewage at the bottom of the aeration tank 203, so that impurities entering the aeration tank 203 are prevented from being directly precipitated and cannot fully contact the treating agent and compressed air to cause pollutant residues, and meanwhile, the roller 2044 slides along the surface of the arc plate II 2034, so that the stirring paddle III 2046 is controlled to slide up and down along the connecting shaft 2045 in cooperation with the spring, and the domestic sewage flow direction is disturbed; After impurities in the sewage are completely precipitated, the buoyancy tank 2022 drives the connecting hose to slide upwards or downwards along the guide rod 2033 along with the height of the liquid level, so that the water pump on the connecting pipe 202 pumps the treated domestic sewage into the anaerobic tank 3, the treated domestic sewage is pumped into the anaerobic tank 3, and after being treated by the anaerobic tank 3, the domestic sewage is input into a next-stage treatment device by the drain pipe 301 and is mixed with the domestic sewage input into the next-stage treatment device by the water outlet pipe 1032, and the subsequent treatment is carried out together; finally, impurities in the aeration tank 203 are discharged through the drain 2032, and impurities deposited at the bottom of the aeration tank 203 are stirred and dispersed by controlling the rotation of the stirring paddle II 2043, so that the phenomenon that the impurities harden and cannot be discharged from the drain 2032 is prevented.

The foregoing is merely illustrative and explanatory of the utility model, as it is well within the scope of the utility model as claimed, as it relates to various modifications, additions and substitutions for those skilled in the art, without departing from the inventive concept and without departing from the scope of the utility model as defined in the accompanying claims.
