The third water pump (76) is driven to work by the output of the third servo motor (77) to transport the clear liquid through the second pipeline (72) to the ultrafiltration pre-box (51), and the clear liquid is ultrafiltered through the ultrafiltration tube (52). After ultrafiltration, it flows into the disposal box (61) through the ultrafiltration post-box (54), completing the centrifugal ultrafiltration; In the above step 3, the clear liquid after ultrafiltration is observed through the second observation window (62) on the treatment box (61). If it does not meet the target, the output of the first servo motor (65) drives the first water pump (64) to work, and the clear liquid is returned to the observation box (41) through the reflux pipe (63), and the ultrafiltration process in step 2 is performed again. After the clear liquid meets the target under the observation of the second observation window (62), it is discharged and stored through the discharge pipe (73); In the above step 4, the cleaning nozzle (12) is moved up to a suitable height by the output of the propulsion cylinder (11), and then the cleaning nozzle (12) sprays clean water onto one side of the filter (23) to flush the residue on the other side of the filter (23). At the same time, the cleaning rod (14) and the cleaning brush (15) are driven to rotate by the output of the second motor (13), and the pushing spring (16) provides a pushing force to ensure that the cleaning brush (15) is closely attached to the inner wall of the filter (23) for cleaning. At the same time, the output of the first motor (22) drives the rotating drum (24) and the filter (23) to rotate, thereby completing the comprehensive cleaning of the filter (23); the output of the rotating motor (43) drives the connecting rod (44) and the rotating brush (45) to rotate, thereby cleaning the inner wall of the first observation window (42).
