Specific embodiment
As shown in Fig. 1 ~ 3, a kind of livestock breeding wastewater AO processing systems, including pretreatment pool 1, the MBR ponds 2 being sequentially communicated
With sterilization pool 3, the AO processing systems that two-way is in parallel, the AO processing systems are connected between the pretreatment pool 1 and MBR ponds 2
System includes the first anoxic pond 4, the first Aerobic Pond 5, the second anoxic pond 6 and the second Aerobic Pond 7 that set gradually, sets at two AO
Reason system is so that when AO processing systems break down or overhaul all the way wherein, another road still ensures that wastewater treatment machinery enters
OK, the treatment of breeding wastewater is not influenceed.
In the present embodiment, grating filter screen is provided with the pretreatment pool 1, it is larger in grating filter screen removal waste water
Impurity after enter back into AO processing systems, be connected with the MBR ponds 2 towards the first anoxic pond, the first Aerobic Pond, the second anoxic
The mud return line 8 of pond and the second Aerobic Pond, is provided with sludge reflux pump on the mud return line, the clear water in MBR ponds enters
In entering sterilization pool, and sludge then returns to AO processing systems and proceeds anoxic treatment and Aerobic Process for Treatment, and the AO techniques of two-stage are to having
Machine thing, ammonia nitrogen etc. have removal efficiency higher, and the removal effect of COD is good, simple structure, reduced investment；MBR technique floor spaces
Small, treatment effeciency is high, strong shock resistance, Operation Administration and Maintenance convenient, can effectively reduce the bacterium in waste water, effluent quality
Stabilization.
In the present embodiment, quartz burner is provided with the sterilization pool, clear water is carried out disinfection with by ultraviolet
Treatment, is also associated with rinsing the backwash tube 9 of membrane module in MBR ponds on sterilization pool, be provided with the backwash tube anti-
Flushing pump, the MBR films in membrane module use hollow-fibre membrane.
In the present embodiment, the first anoxic pond and the second anoxic pond bottom are laid with boring aeration pipe 10, the first anoxic pond
With diving mixer 11 is additionally provided with the second anoxic pond, the spacing between adjacent two boring aeration pipes 10 be 600mm, perforation
The setting height(from bottom) of aeration tube 10 is 300mm.
In the present embodiment, first Aerobic Pond and the second aerobic bottom of pond portion are laid with microporous aeration disc 12, adjacent two
