Abstract:
The membrane biofilm reactor (MBfR), a novel membrane treatment technology, has attracted considerable attention because of its appreciable pollutants removal efficiency, high gas utilization rate and no secondary pollution. Taking MBfR as the research object, the classification and working principles of MBfR reactors are systematically introduced. The problem of gas back diffusion commonly existing in MBfR is discussed in detail. The influencing factors of back diffusion, such as gas supply mode, gas supply pressure and gas retention time, biofilm activity and membrane material properties, are summarized. Eventually, the possible control measures for gas back diffusion are prospected.
