Below with reference to embodiment, the utility model will be further described.
Embodiment 1
In conjunction with Fig. 1-2: a kind of AOAO-MBBR two-stage water sewage-treatment plant, including one area of anoxic, MBBR aerobic one
Area, 2nd area of anoxic, aerobic 2nd area MBBR and settling zone, one area of anoxic, the aerobic area the MBBR, 2nd area of the anoxic and
Aerobic 2nd area MBBR is in matts distribution clockwise, and the settling zone is located at one area of anoxic and the MBBR aerobic two
The side in area；Water inlet pipe is equipped at 2nd area of one area of anoxic and the anoxic, the settling zone is equipped with outlet pipe；It is described to lack
One area of oxygen, 2nd area of the anoxic, the aerobic area MBBR and 2nd area the MBBR side wall on be equipped with water hole；The settling zone
Reflux line is connected between bottom and an aerobic area；It is equipped with agitating device in an aerobic area and aerobic 2nd area,
The agitating device includes stirring motor and mixing drum, and the central axis of the mixing drum is connected with the axis of the stirring motor.
Further, composite filling is equipped in an aerobic area and aerobic 2nd area.
Further, the aerobic area the MBBR and the aerobic 2nd area bottom the MBBR are equipped with perforated pipe aerating regulation system, and
Equipped with MBBR floating stuffing.
Further, the water hole of two area's side wall of one area of anoxic and the anoxic is located at low level；The MBBR
The water hole of aerobic area side wall is located at a high position, and the water hole of bis- area's side wall of MBBR is located at middle position, in anoxic
When agitating device in 2nd area of one area and anoxic is stirred, negative pressuren zone is formed on the bottom in 2nd area of one area of anoxic and anoxic, thus
