the advantage of Moving Bed Biofilm

Moving bed biofilm  using biofilm method of the basic principles, combined with the advantages of traditional activated sludge method, but beyond the activated sludge and biofilm method of the shortcomings and limitations. PVDF (PVDF) hollow fiber membrane application to replace the traditional activated sludge method in the secondary settling tank, the solid-liquid separation, effective to achieve the purpose of mud separation. The efficient interception of the membrane can greatly increase the concentration of bacteria in the biological pool, so that the biochemical efficiency is greatly enhanced, effectively remove ammonia nitrogen, phosphorus and difficult to degrade macromolecular organic matter. The fluidized bed system has the following advantages:

  •  Saving space: an area of only one-fifth to one-tenth of the traditional method, and canceled the second pool. The traditional “early sinking, biochemical and secondary sink” three steps into a step
  •  save time: twice as fast as the traditional method, just 2 to 6 hours
  •  no sludge backflow or circulating backwash; sludge production is minimal
  •  simple operation: the process can be automated, easy to operate and control
  •  not blocked: carrier biology (Biomass) in the turbulence continue to fall off, to avoid clogging
  •  stable biofilm system, bio-easy to restore vitality: biological changes in temperature and pH, overload or toxic effects can also quickly restore vitality, so that the treatment effect is stable.
  • configuration flexibility: biochemical pool design flexibility, according to the processing requirements and the size of the use of different configurations
  •  built sewage system transformation, upgrading and expansion is very convenient
  •  lower investment costs and operating costs
  •  more stable water quality, from the system of water quality fluctuations; more clean water, suspended solids and turbidity close to zero, can be directly used
