Topic；The shortcomings of big integrated film biologic treating technique investment, high energy consumption, inconvenient operational management is avoided simultaneously.And then provide one
Integral type SAFO-MBBR decentralized wastewater treatment for reuse method is planted, process is reached by synchronous nitration denitrification denitrogenation dephosphorization technique
The purpose of reuse low ratio of carbon to ammonium decentralized wastewater.
Concretely comprise the following steps：
(1) a kind of integral type SAFO-MBBR decentralized wastewater treatment for reuse device is set, is can be made into vertical, horizontal, circular or square
Shape and vehicle-carried mobile formula, including Biochemistry Reaction System, 3 part of settling system and advanced treatment system.Biochemistry Reaction System includes
Pushing flow mixer, MBBR fillers, aeration tube, device interior space are separated to form anaerobic zone, simultaneous oxygen by controlling aeration and dividing plate
Area, aerobic zone.Settling system top includes inclined tube separator and effluent weir, effluent weir connection settling system outlet pipe, outlet pipe
Top connects chemical feed pipe, and settling system bottom is provided with discharge pipeline and sludge reflux seam；Advanced treatment system top includes sparge pipe
With water leg, bottom includes filtrate, water outlet/backwash tube.
Two) in Jing steps (), the sewage of anaerobic zone is acted on by pushing flow mixer, with returned sludge blending and by plug-flow
To aerobic area, subsequently into the aerobic zone equipped with MBBR fillers, while under gas with the effect of waterpower plug-flow, aerobic zone mixed liquor
Aerobic area is partly refluxed to, realizes that mixed-liquor return is acted on.
Three) the reacted mixed liquor in aerobic zone enters settling system, under the effect of inclined tube separator completes mud-water separation, dirty
Mud is heavier, and partial sludge is back to anaerobic zone through sludge reflux seam, and then realizes flowing back certainly for sludge, and excess sludge is in gravity
Discharge through gravity discharge pipeline under effect；Water after process enters outlet pipe through overfalling weir, and advanced treating system is entered after dosing
System.
Four) sewage Jing after step () (two) (three) process enters contact filter, tiny flocculation under gravity stream effect
Sewage afterwards is intercepted by filtrate, partial flocculation thing, and filtered water flows into collecting-tank by outlet pipe and carries out reuse.When on filtrate
When portion's water level reaches designated water level, backwashing water and gas are redirected back into filter tank by outlet pipe, complete backwash, after backwash
Waste water drains into regulating reservoir by water leg.
This have the advantage that：
(1) method of the present invention is reasonably integrated with membrane processing method by traditional activated sludge process, overall plug-flow and local mixing
Sludge form and film itself microenvironment can preferably realize synchronous nitration denitrification denitrogenation dephosphorization, while aid in deep phosphorous removal
Technology, effective treatment for reuse decentralized wastewater.
The device simple structure for using, operating in a key are easy to operation maintenance of constructing；Can be made into according to different scales vertical
The various ways such as formula, horizontal, circular or square；Vehicle-carried mobile formula can be adopted simultaneously according to the characteristics of decentralized wastewater, improved and divided
The service efficiency of scattered sewage treatment facility.
The energy consumption needed for sludge reflux and mixed-liquor return in conventional activated sludge process is saved, abnormal smells from the patient and noise are little,
Process water and energy-saving and environmental protection, efficient water treatment efficiency can be really achieved with qualified discharge.
