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.

2.2 MBR process description

MBR is a kind of new type sewage treatment technique which combine activated sludge manner and integrated immersed membrane separation system, this process can be widely used in municipal and industrial sewage treatment area, which contain water resource reuse,community development, park scenic water source reuse etc.

It is a new kind of sewage treatment technique, MBR has widely apply in all over the world sewage treatment plant.

Typical MBR system process can be described as following:

The sewage enter into equalize tank pass by 1-2mm 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.

2.2.1Membrane module description

MBR system use hollow fiber membrane to make solid-liquid separation. The NL series immersed hollow fiber membrane is special developed membrane module. It has higher filtering efficiency, it can effective remove bacteria,suspended particles and impurity, thus get the superior filtering water. In additional, due to each unit membrane module filtering area big, small membrane installation occupy volume, decrease reactor volume and occupy area.

2.2.2Application scope:

* Hotel,restaurant,community etc domestic sewage treatment recycle

* Industrial and mining enterprises,remote village,sentry ,tourist area etc domestic sewage recycle.

* Each kind of industrial sewage (similar to domestic sewage) :such as hospital sewage,pharmaceutical sewage ,washing sewage,food sewage etc

2.3 Influent and effluent water quality



2.4 Feature:

* This system with containerized package function: make the anoxia tank,MBR bio-reaction tank,sludge tank,cleaning water tank and operation room integrated into a big tank body, compact structure, process concise, small occupy area ( only traditional process 1/3-1/2) ,increment expansion convenient, high automatic degree, operating maintenance conciseness, it can move at anytime and anywhere, it can move to treatment goal location, direct large-scale to make proceed treatment, no need make twice construction.

* Gather sewage treatment and water purification process into one system, it shallow buried underground or ground; the treatment basic no sludge generate, hasn’t influence to surrounding; better operation effect,high reliability,effluent water quality steady,little operation cost.

* In treating municipal sewage, impact resistance,high remove efficiency to pollutant, strong nitration ability, it can make nitration,denitrification, both nitrogen and phosphorus removal function, suitable for treat municipal sewage,distributed sewage, the effluent can be reuse or can be discharge after reach standard, it can meet different users of different water quality.

* cleaning disinfection tank equip with packing which made of new type environmental protection active ion material, it has disinfection function and can effective remove the heavy metal ion in water, it can overcome medication washing disinfect caused secondary pollution and reduce the heavy metal content in effluent, greatly improve the recycle water quality.

* The aeration pipeline of membrane bio-reactor divide two parts, 1 part is make aeration to surrounding activated sludge , another part is make aeration to membrane module.

Its advantage is to make the membrane module mutual flap by aeration membrane module produce scour force, thus it can shake off the calcified sludge adsorb in the membrane fenestra surface, make the membrane flux greatly extend the membrane service life, thus reduce operation cost.

2.5 MBR treatment process:
