Summary of the invention
The utility model provides a kind of Orbal oxidation Ditch Technology and mutually ties with MBR membrane technology precisely in order to overcome above-mentioned deficiency
A kind of Orbal/MBR integrated reactor for the processing Rural Waste Water closed, can denitrogenation dephosphorizing, further through MBR membrane technology,
Pollutant more effectively in removal country sewage, allows final outflow water to stably reach " urban wastewater treatment firm pollutant
Discharge standard " level-one A standard in GB18918-2002;In addition, the utility model remotely controlled by Online Monitoring Control platform/
Entire sewage disposal process is monitored, realizes automation, intelligent operation, package unit reduces occupied area by shared pool wall,
Manufacturing cost is further reduced that occupied area is small and production cost in addition apparatus main body uses integrated molding technology.
In order to reach above-mentioned purpose of utility model, specifically it is performed by: a kind of Orbal/ handling Rural Waste Water
MBR integrated reactor, ditch pond and Center Island including four concentric and adjacent shared furrow banks, it is characterised in that from outmost
Ditch pond is successively designed as aerobic tank, the second anoxic pond, anaerobic pond, the first anoxic pond, MBR film exhalant region, water inlet pipe to Center Island
Anaerobic pond is accessed, between anaerobic pond and the second anoxic pond, the second anoxic pond and aerobic tank, the first anoxic pond and MBR film exhalant region
Shared furrow bank on be equipped with water hole, between aerobic tank and the first anoxic pond be equipped with connecting pipe, MBR film exhalant region connection water outlet
Pipe.Sewage accesses anaerobic pond by water inlet pipe, and the mixed liquor in anaerobic pond successively flows into the second anoxic pond, good by furrow bank water hole
Oxygen pond, then the first anoxic pond is entered by the connecting pipe between aerobic tank and anoxic pond, then center is flowed by furrow bank water hole
Island MBR film exhalant region, is finally discharged by outlet pipe.The design is by Orbal technique in conjunction with MBR membrane technology, and not only device is whole
Rationally distributed, occupied area is few, and space utilization rate is high, and will form microbial film in sewage disposal process, and sewage is through micro-
The further filter sewage of MBR film is penetrated after biological film process, Nitrogen/Phosphorus Removal more preferably, guarantees that final outflow water reaches level-one A's
Standard.
Preferably, ditch pond and Center Island shape can be annular for annular, ellipse, rectangle, optimal selection.
Center Island MBR film exhalant region is provided with stripping reflux device, and return pipe is connected to the second anoxic zone, stripping reflux device
By the part mixed liquor stripping reflux of Center Island MBR film exhalant region to the second anoxic zone, remaining mixed liquor is discharged by outlet pipe.
Preferably, MBR film exhalant region lower part, aerobic bottom of pond portion are equipped with aerator, throwing in anaerobic pond, aerobic tank has spherical shape
Or other floating stuffings.
Preferably, the stripping reflux device on the aerator and MBR film exhalant region of MBR film exhalant region, aerobic tank passes through
A piece shared air inlet pipe is connected with blower.
Preferably, Center Island MBR film exhalant region uses plate membrane or curtain type membrane, optimal selection is plate membrane, in mistake
Microbial film can be formed when filtering sewage.Preferably, MBR film divides dry hole plate framework using integrated injection molding.
Preferably, steel plate, brick or plastics can be used in the main material of this reactor, especially with injection molding, rotational moulding, thermoplastic one
Body chemical conversion type is preferred, the best optional PP material of material.
Preferably, being provided with underwater impeller in aerobic tank, the second anoxic pond, anaerobic pond, the first anoxic pond, under water
Impeller enclosure material optimal selection is plastics.
Preferably, reactor package unit is equipped with Online Monitoring Control platform, can remotely be controlled by Online Monitoring Control platform
Aeration time, the aeration quantity of MBR film exhalant region and aerobic tank processed, the stripping reflux device of MBR film exhalant region are back to second and lack
The regurgitant volume in oxygen pond.
The utility model has the advantage that compared with traditional sight technology
1. will form microbial film in sewage disposal process by MBR membrane technology, sewage is saturating after microbial film is handled
The further filter sewage of MBR film is crossed, guarantees that final outflow water reaches the standard of level-one A;
2. the sludge concentration of biochemistry pool can be increased by membrane separation technique, 6-10 grams per liter is reached as high as, is improved biochemical
Pond sewage treating efficiency reduces BOD sludge loading and total nitrogen total phosphorus load.
3. apparatus main body use injection molding, rotational moulding, thermoplastic integrated molding technology, reliable operation, product lightweight, manufacture at
This is low, and the reinforced concrete occupied area compared with site operation is reduced significantly, and speed of application greatly promotes, and has greatly economic effect
Benefit;
4. using automation remote control technology, the long-range entire sewage disposal process of control/monitoring realizes automation, intelligence
Energyization operation;
5. using oxidation Ditch Technology, so that device integral layout is reasonable, space utilization rate is high;
6. being provided with underwater impeller in aerobic tank, the second anoxic pond, anaerobic pond, the first anoxic pond, pushed away by adjusting
The quantity for flowing device, increases the mobility and cyclicity of water, and interior quantity of circulating water is made to improve several times or more.
