Membrance bioreactor sewage water treatment system
What is the MBR?
Product Description
Membrance Bioreactor(MBR) is a kind of advanced technology developed since the end of 20th century which realized the efficient combination of menbrance separation technology with biological technology .The menbrance separation separation technology replaces the traditional active sludge method and the noraml filter unit ,its strong separation ability can make the SS turbidity near to be zero Hydraulic retention time sludge age is completely separated ,the outlet water is good and stable in quality ,it can be reused without the third level treatment ,due to the high security and economic and effective water ,it greatly expands the scope of application of waste water recycling .
Technological process
Sewage -Grille -Regulating pond-MBR Bioreactor-Discharge(reuse)
Features
Because of the high-efficiency solid liquid separation ,it can efficiently remove the SS ,colloidal material and dead mircobe in the sewage, no dead sedimentation tank ,or filter device ,nor other solid-liquid separation device .
The MBR can make the biomass in biological treatment unit maintain high concentration ,thus highly improve the volume loading .meanwhile ,the high effcient membrance separation can shorten the HRT .The device is with a compact structure and small space occupation.
MBR can filter out bacteria,part of the harmful material such as virus,it can obviously save dosing disinfection dosage,greatly improve the quality of the output water and reduce the operating cost and widen the scope of application of water
Due to the strong interception function of MBR,it can keep the mircobe in the reactor to avoid the loss of all kinds of mircobe groups.which is good for the growth of the bacteria at the same time ,it can lengthen the residence time of difficult degradable macromolecule organics to improve the decomposition so as to make the metabolic system process smoothly ,the system has s strong impact resistance and wide suitability .
It can realize the completely separation of HRT and SRT .By the extended aeration ,it can consume the organics,it can theoretically achieve the effect of no excess sludge emissions.thus reduce the surplus sludge treatment costs sigificantly .
The unique mode of operation makes the membrance surface no blocking ,and the cleaning interval time is long .the way to clean the menbrance is easy .since the menbrance module can be separately cleaned ,thus the maintenance is convenience and simple .the module design make the machine flexible ,it is easy to expand volume .
