MBR biological treatment processing

   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 bioreactor system greatly intensify the bioreactor function by membrane separation.

Process:

The sewage enter into regulating tank to ensure the steady water quality and quantity, the effluent from regulating tank enter into pretreatment tank, due to different water quality adopt according pretreatment technics. The sewage after pretreatment enter into MBR reaction tank directly, all kinds of organic matter in sewage proceeding oxygenolysis in action of actived sludge , which will discharge out after pass membrane module separation in MBR pond, the sludge in mixed liquor and organic matter not fully decomposition will hold back in MBR pond, go on proceeding decomposition and digestion, till degraded completely.

characteristic:

1. better effluent water quality, use superfine the membrane filter components, Replace secondary settling pond , which can make bioreactor get higher biological concentration contrast common actived sludge , improve biodegrability, with better treatment effect, the effluent water quality is high after membrane separation,

2. Membrane bioreactor can control longer SRT, make the nitrobacterium enrichment , improve the nitration effect; make the macromolecule granulate ingredient has enough retention time, thus reach the purpose of higher removal rate.

3. compare with the traditional Water reuse treatment processes, this processing route is very simple, small occupy area, small sludge , long sludge discharge cycle .

4.has advantage in High BOD5 or CODcr,high SS and poor sludge settling effect,

Impact load big wastewater treatment etc..
