Product Details

Membrane bio---reactor is a kind of new type sewage treatment technique which combine high efficient membrane separation technique and activated sludge manner, it inherit membrane separation technique and biochemical treatment technique feature and intensify biochemical treatment effect, it can used in high organic content municipal or industrial sewage treatment.

2.1 Compare to traditional activated sludge, MBR has the following advantage:

1) 0.05 micro membrane filtering outlet water, the effluent water suspended solid and turbidity can close to zero, can be reuse directly

2) Compare to traditional treatment system, it can save 50% land usable area;

3) Due to membrane high efficient intercept action, micro organism fully intercept in reactor , realize reactor hydraulic retention time and sludge age fully separation, to make operation control more flexible and steady;

4) The micro-organism concentration in bio-reactor can reach 5000-8000 mg/L, with high biochemistry efficiency, strong impact resistance;

5) Long sludge age, in favor of slowly accretion nitrobacteria Intercepting growth and breed, system nitration efficiency increase;

6) Reactor is operate in high volume loading,low sludge loading,long sludge age condition , surplus sludge discharge volume.

7) Membrane separation to make the big molecule difficult degrade into bioreactor has enough retention time, greatly improve difficult organism degrade efficiency;

8) System with high automation degree, adopt PLC control, can realize whole automatic control;

9) Modular design, compact structure, small occupy area ,low operation cost

After many years of sewage treatment project experience, start MBR sewage treatment technique has the following feature:

1) Membrane material is polyvinylidene fluoride, strong stain resistance, easy to washing, suitable for sewage treatment; chemical properties stable, strong oxidation resistance, it can adopt common oxidability agentia washing.

2) Membrane flux higher than other material (such as PP or PE) similar product, adopt periodically,chemical backwashing and chemical washing process guarantee membrane module water output ability and membrane flux.

3) Low trans-membrane pressure, usually is 0.01~0.06 Mpa, it can adopt siphon principle and no need suction power can output water, low operation cost.

4) MBR technology adopt anoxia and aerobic combining form, sewage enter into anoxia zone, make the big molecular weight long chain organism resolve into easy biological organism, then enter into aerobic area to make organism biological degrade , at the same time, to make biology nitration reaction, and make denitrification reaction,

and by backflow to anoxia area to make denitrification, finish denitrification function.

Main treatment unit
(1) Front pretreatment tank:

In front of this device is anoxia tank, in one end of anoxia tank set water inlet, another side top set water weir tank and outlet water, can make the sewage stable nature flow into membrane reaction tank, equip floating packing and anoxia sludge, the sludge in anoxia tank HRT is 3-8h, give oxygen by interval, to make acidify,nitration and denitrification function, make the organism gradate translate into inorganics remove.
(2)MBR bio-reaction tank:

It has set water inlet in one side, and the immersed flat membrane module set in reaction tank, accommodate activated sludge, around aeration and membrane unit aeration pipeline connect with air blower, the matched collecting pipe in membrane module connect with suction pump, the untreated sewage enter into MBR biochemical reaction tank by water inlet, sewage HRT is 5h in reaction tank. After degrade by activated sludge in reaction tank, by resistance pollutant flat membrane module, then enter into cleaning water disinfection tank by suction pump. There set sludge lifting pump in aeration, it can lift the surplus sludge to sludge digestion tank interior; there has overflow in reaction tank top, it can make the sewage backflow into tank outside equalize tank; in below side open vent , in order to convenient for tank interior maintenance, cleaning.
(3) Sludge tank:

there are set sludge collecting hopper and sludge pipeline in sludge tank bottom, in order to convenient for sludge concentration, set weir water tank in top, there open mud discharge inlet in bottom, rely on static pressure automatic discharge mud.
(4)Cleaning water tank:

(5) Operation room:

It set 2 pcs air blower in operation room, operate 12h automatic shift 1 time, air blower equip with silencer damping measures; suction pump 2pcs, electric control cabinet 1pc, lighting system; in the top, equip with rain-proof air vent and ventilate convection device.

The above treatment unit integrated in a tank body, electric control cabinet automatic control each power plant operation.
