NOVELTY - A domestic sewage biological integrated processing device comprises a main container (8), a sewage feeding guide pipe (4), an aerator (5) and a slurry discharging guide pipe (6). The main container is provided with a first aerobic reaction chamber (1) and a second aerobic reaction chamber (2) surrounding outside the first aerobic reaction chamber. The space in the main container except the two aerobic reaction chambers forms a clearing chamber (3).    USE - A domestic sewage biological integrated processing device.    DETAILED DESCRIPTION - A domestic sewage biological integrated processing device comprises a main container (8), a sewage feeding guide pipe (4), an aerator (5) and a slurry discharging guide pipe (6). The main container is provided with a first aerobic reaction chamber (1) and a second aerobic reaction chamber (2) surrounding outside the first aerobic reaction chamber. The lower bottom surfaces of the two reaction chambers are respectively overlapped with a part of the lower bottom surface of the main container. The side surfaces and upper surfaces of the two reaction chambers are not in contact with the surfaces of the main container. The space in the main container except the two aerobic reaction chambers forms a clearing chamber (3). The sewage feeding guide pipe is inserted into the first aerobic reaction chamber from the upper surface of the main container. The end of the sewage feeding guide pipe in the first aerobic reaction chamber is located at the lower part of the first aerobic reaction chamber. The first aerobic reaction chamber is connected with the upper part of the second aerobic reaction chamber through an opening on the side surface at the upper part. The second aerobic reaction chamber is in communication with the lower part of the clearing chamber through an opening on the side surface at the lower part. The upper side surface of the clearing chamber is provided with a discharging port. The lower bottom surfaces of the two reaction chambers are respectively provided with a slurry discharging port. The slurry discharging ports are connected with the slurry discharging guide pipe through slurry discharging valves; and the aerator aerates into the two reaction chambers through multiple air feeding guide pipes.
