Mobile Camp sewage treatment plant 50m3/d 100m3/d mbbr mbr package sewage treatment plant system

The sewage continuous pass by the suspended padding internal of MBBR reactor, it will form biomembrane inside and outside padding surface, in the action of microorganism in biofilm, make the sewage purified. the Packing move freedom in the action of mixed liquor convolute and reversed in reactor.

MBBR reactor with characteristic of bearing impact load , long sludge age, small excess sludge, with high efficiency and operate flexibility of activated sludge process, comparing with technology, with the characteristic:

（1）the sludge concentration higher, ordinary sludge concentration is the 5～10 times activated sludge process, the sludge quality concentration in aeration pond can reach 30～40g/L .

(2) no easy blocking, no need backwashing and backflow.

（3）as suspended padding of the process core with the aerobic and anaerobic metabolism, can better denitrification and dephosphorize.

MBBR technique feature

1).The MBBR reactor is developed in the base of biological filtering tank and biological fluidized bed technique ; it not only has the traditional biological;

2).Membrane manner advantage of resistance to shock loading, sludge age long, less residual sludge, but also has the activated sludge high efficiency and operation flexibility, it has the following feature:

3).small occupy area

4).Large amount of activity of microorganisms

5).MBBR biofilm carrier is fluid, due to water shear force and water movement generated friction, biofilm on the surface of the packing will fall off naturally, part of the sludge with water flow out reactor, part of the sludge still remains in the reactor, make the effect of activated sludge function . Sludge concentration is 5 ~ 10 times of ordinary active sludge, purification function increased significantly; Microbial phase diversity, biological food chain is long. So it won’t blocking, no need backwashing and backflow, small water head loss.

6).superior denitrification

7).Packing formed good breeding, anoxic and anaerobic environment, nitrification and denitrification reaction can happen in a reactor, removal of ammonia nitrogen has a good effect.

8).better removal organism

9).Reactor with high sludge concentration, sludge concentration commonly 5 ~ 10 times of the normal activated sludge process, can be as high as 30 to 40 g/L. Improves the processing efficiency of organic matter, and because of packing, water is in motion, so the gas, water, good mass transfer between solid filler on biofilm activity, enhance the organic load and efficiency of the system.
