Plate, the bottom of first dividing plate is tiltedly installed with first baffle；Second is provided between the settling zone and the guiding region
Dividing plate, the bottom of the second partition is tiltedly installed with second baffle, and the lower end of the second partition is provided with water hole；It is described
The top of first dividing plate is higher than the top of the second partition；Backflow is provided with below the guiding region and the settling zone
Slope, the one end on the backflow slope puts in the aeration zone.
It is preferred that, it is provided with above the settling zone above effluent weir, the effluent weir and is provided with outlet pipe.
It is preferred that, the junction of the outlet pipe and the effluent weir is provided with filter.
It is preferred that, the top of first dividing plate is higher than 0.5~1m of top of the second partition.
It is preferred that, the angle between the first baffle and first dividing plate is 120 °~150 °, the second baffle
Angle between the second partition is identical with stating the angle between first baffle and first dividing plate.
It is preferred that, the bottom of the first baffle puts in the aeration zone, and the bottom of the second baffle puts in described sink
Shallow lake area.
It is preferred that, the backflow slope sets camber, and radian is between π/6~pi/2.
It is preferred that, the aerator is one kind in tubular type aerator or boring aeration device.
It is preferred that, the water inlet pipe is the porous water inlet pipe of staged.
The sewage treatment process that a kind of use high-efficiency aerobic reactor is carried out, is comprised the following steps that：
(1) sewage is entered in the aeration zone by the water inlet pipe, is arranged on the aerator in the aeration zone
Gas is sprayed upwards, and under the promotion of gas, sewage and sludge fully contact mixing in the aeration zone；
(2) liquid level of mud mixture is lifted up, until the top of first dividing plate, mud mixture is crossed described
First dividing plate is entered in the guiding region, and partial sludge is back in the presence of deadweight on the backflow slope；
(3) remaining mud mixture is entered in the settling zone by the water hole on the second partition, in institute
State in settling zone and staticly settle, on the sludge reflux precipitated to the backflow slope, treated water is from the effluent weir
On drainpipe be discharged into subsequent treatment；
(4) sludge reflux being deposited on the backflow slope to being reacted again with sewage mixing in the aeration zone,
Recycle.
Due to the utilization of above-mentioned technical proposal, the present invention has following beneficial effect compared with prior art：
(1) double precipitations are formed using settling zone and guiding region, sludge is precipitated completely, be conducive to improving precipitation separation effect
Really；
(2) current in aeration zone are moved from top to down, and sludge is to move from below to up, and the sludge of backflow can be entered
Row washes away, and forms granule sludge, improves the concentration of activated sludge；
(3) sludge reflux precipitated, into aeration zone, will be reacted with sewage mixing again by slope of flowing back,
Recycle；
(4) aeration zone in aerobic reactor, guiding region and settling zone independent partitions, isolated operation, easily facilitate desilting,
Maintenance and maintenance；
(5) aeration, water conservancy diversion and depositing technology are combined together, floor space is saved in a variety of sewage treatment process combinations,
Improve treatment effeciency.

Inside staticly settle carry out mud-water separation, on the sludge reflux precipitated to backflow slope 12, treated water is from effluent weir 13
On drainpipe 14 be discharged into subsequent treatment.
(4) sludge reflux being deposited on backflow slope 12 is circulated sharp to being reacted again with sewage mixing in aeration zone 2
With the sludge concentration to strengthen aeration zone 2 improves degradation effect.Because the aeration of aerator 6 is acted on, on current direction, promote
Make the sludge reflux that the bottom of reactor body 1 is formed on negative pressure, acceleration backflow ripple 12 to aeration zone 2.
