The stirring rod (48) moves to drive the stirring blade (49) to move left and right to stir the ammonia nitrogen wastewater in the inner cavity of the wastewater stirring box (2) to prevent the ammonia nitrogen wastewater from precipitating. S3: Then the water pump (6) is started, and the water pump (6) is started to pump the ammonia nitrogen wastewater in the inner cavity of the wastewater mixing tank (2) through the water pumping pipe (5). The ammonia nitrogen wastewater is pumped into the inner cavity of the wastewater filtering treatment tank (8) through the water pumping pipe (5), the water pump (6) and the outlet pipe (7), and then guided into the top of the air-water separation membrane filter (10) through the guide plate (11). The ammonia nitrogen wastewater is filtered through the air-water separation membrane filter (10), and then the filtered water is discharged through the drain pipe (9); S4: When brushing and cleaning the air-water separation membrane filter (10), the third motor (123) and the fourth motor (129) are started. The fourth motor (129) rotates to drive the rotating column (1210) and the cleaning brush plate (1211) to rotate. The cleaning brush plate (1211) rotates to brush and clean the top of the air-water separation membrane filter (10). The third motor (123) rotates to drive the rotating disk (124) to rotate. The rotating disk (124) rotates to drive the right end of the push-pull rod (125) to rotate in a circular shape through the rotating pin, so that the left end of the push-pull rod (125) pushes or pulls the connecting block (126) to move left and right through the rotating pin. The connecting block (126) is moved left and right. 6) The movable plate (127) and the second movable mounting plate (128) are moved to move, the movable plate (127) moves to drive the guide sleeve (1212) to slide on the surface of the guide rod (1213), the second movable mounting plate (128) moves left and right to drive the fourth motor (129) to move, the fourth motor (129) moves to drive the rotating column (1210) to move left and right in the inner cavity of the second sliding groove (122), the rotating column (1210) moves left and right to drive the cleaning brush plate (1211) to move left and right to move and brush the top of the air-water separation membrane filter (10) to clean, thereby preventing the air-water separation membrane filter (10) from being blocked and improving the filtering efficiency.
