MBBR moving bed biofilm technology

Updatetime:2015-03-18 Click:

      MBBR technology is use of the basic principles of biofilm, make full use of the advantages of activated sludge, to overcome the shortcomings of conventional activated sludge process and fixed biofilm. Under this method, it can still achieve high nitrogen removal in addition to carbon when sewage biodegradability is poor, carbon and nitrogen is relatively small. It is very suitable for handling high nitrogen content of the starch industry wastewater treatment projects.
Superiority:
1、Effect of water and gas distribution is good; filler without clogging; efficiency of mass transfer and high oxygen transfer is high; good purifying effect.
2、Flexible design, easy filling and maintenance, easy to existing sewage facilities expansion project.
3、Biofilm updated timely, high mass transfer efficiency, reduce sludge volume by 40-60%, save the cost of sludge treatment.
4、As microbes on the filler contact with the air bubble for a long time, it can play a bubble shear and adhesion barrier during exercise. Oxygen utilization can be increased by 2-5%, reduce energy consumption.
5、It can achieve simultaneous nitrification and denitrification which has high efficiency.
6、Filler has create a good environment for microbial growth, which conducive to long sludge age nitrification bacteria growth and high ammonia removal efficiency.
7、SRT long, no sludge bulking; high effective concentration of sludge, COD volume loading 4 ~ 8kg / m3 • d.
