Product Description

MBR sewage treatment plant

MBR is a kind of brand new sewage treatment technics which combine Superfine filter components and bioreactor. Membrane separation plant hold back the activated sludge and macromolecule in biochemical reaction basin, omit secondary settling pond. the sludge depth greatly improved, HRT and SRT can separately control, the nonbiodegradable material constant reaction ,degradation in reactor. Membrane bio-reactor system greatly intensify the bioreactor function by membrane separation.

The sewage enter into equalize tank pass by 1-3mm bar screen, used to equalize water quality and volume. The intercept impurity need clear up in regular. Next, the sewage in equalize tank will pump to MBR system, in MBR system realize mirco-organism resolve reduction ,which contain aerobic and anoxia reaction area, the can't degrade impurity and activated sludge will intercept in the membrane tank , the membrane filtering output water will reach standard reuse or discharge.
The sewage first pass by bar screen (mechanical bar screen or manual bar screen), bar space is 3mm, used to gain big particle suspended solid and impurity, then flow into equalize tank interior, to make the water quality,volume in equalize tank, then lift the sewage into anoxia tank by sewage lift pump, after hydrolytic acidify by anoxia tank, enter into MBR biochemical treatment system. Whole set of bio-chemical treatment system is composed of front pretreatment and reaction tank, according to influent water quality and effluent water quality requirements, which decide if need and design leading treatment end. In reaction tank equipment immersed plain film, constitute MBR- aerobic running mode.
MBR reaction tank effluent water direct enter into PE recycle tank, discharge or pump into reclaimed water pipe network to recycle.

 

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.

MBR plant selection
1,before chose this MBR plant, first make clear of sewage nature, the influent water quality and volume required treatment standard. Each industrial sewage, the PH of sewage must be control 6.8-9, it shouldn't contain the excess element which hamper microbial growth.
2,Equalize tank should supplied or construct by user, it is concrete tank body usually, its volume should confirm according to drainage period ,production process etc factor , its volume is water flow rate 4-10 times.
3,The MBR plant can design vertical and buried two types, it can lay on the ground according to client requirements, or buried below the earth's surface. 
4,If plant use in cold region, it need make antifreezing treatment to guarantee equipment normal operation in winter.
 

Main Features

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) The micro-organism concentration in bio-reactor can reach 5000-8000 mg/L, with high biochemistry efficiency, strong impact resistance.
4) System with high automation degree, adopt PLC control, can realize whole automatic control;

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