The aerobic reactor 2 is communicated through aerobic reactor overflow port 6 with the sedimentation basin 10；The anaerobic reactor overflow
Mouth is higher than the aerobic reactor overflow port, and sewage inlet 12 is arranged in the anaerobic reactor, and offgas outlet is arranged in top,
Oxygen-containing gas entrance is arranged in the aerobic reactor bottom, and offgas outlet is arranged in top, after sedimentation basin setting processing
Outlet of sewer and sludge outlet.
Preferably, mixer 3 is set in the anaerobic reactor.The mixer 3 is that liquid phase can be promoted to flow
Equipment, preferably agitating device or pump.
Preferably, setting complex carrier bed 4 in the aerobic reactor 2.
Preferably, the sewage inlet extends to the anaerobic reactor bottom through pipeline, and is set in sewage inlet
Set liquid distribution trough.
Preferably, gas distributor is arranged in the oxygen-containing gas entrance of the aerobic reactor bottom.
Preferably, the cross-sectional area of the anaerobic reactor is less than the cross-sectional area of the aerobic reactor.
Preferably, the anaerobic reactor 1 and the aerobic reactor 2 are the cylinder of coaxial arrangement.
Preferably, outlet of sewer is connected to through pipeloop with the anaerobic reactor after the processing, the place
Sludge outlet is connected to through pipeloop with the anaerobic reactor after reason.

Sewage-treatment plant provided by the utility model, it is preferable that the anaerobic reactor and the aerobic reaction
Device is coaxially disposed, and as shown in Fig. 1, the sewage-treatment plant is divided into interior cylinder anaerobic reactor 1 and external annulus column
Aerobic reactor 2, anaerobic reactor 1 is high, diameter is small, and aerobic reactor 2 is low, diameter is big, and inside and outside cylinder, which is all closed, not to be connected directly
It connects.The high-concentration sewage 12 come from upstream enters 1 bottom of anaerobic reactor by pipeline, is distributed upwards by liquid phase distributor 7
Flowing.Mixer 3 is installed in 1 inside of anaerobic reactor, promotes liquid phase flowing.Liquid phase flows up, and flow to anaerobic reactor overflow
Mouth 8, then under the effect of gravity, 2 bottom of aerobic reactor is overflowed to by delivery pipe 9.
2 bottom of aerobic reactor has gas distributor 5 to be distributed air 11, ensures that aerobic reaction is smoothed out.In
There is complex carrier bed 4 in portion, and reaction surface and support are provided for aerobic reaction.Aerobic reactor overflow port 6, processing is arranged in top
Overflow goes out waste water from there afterwards, into subsequent processing.Tail gas outlet 14 is arranged at anaerobic reactor 1 and 2 top of aerobic reactor,
The tail gas that anaerobic and aerobic reaction generates goes gas treatment again.The sewage flowed out from aerobic reactor 2, is added after medicament 16,
Into being precipitated in sedimentation basin 10, a supernatant liquor part goes to post-process through pipeline 17, and a part returns to anaerobism through pipeline 15
Processing is re-started in reactor 1；Lower layer's sludge part goes to post-process through pipeline 18, and a part also returns to anaerobism through pipeline 13
