Effect of Extracellular Polymeric Substances on Operation of Membrane Bioreactor

摘要：

　　In order to study the relationship between extracellular polymeric substances (EPS) and membrane fouling,the effect of extracellular polymeric substances (EPS) on the operation of membrane bioreactor (MBR) was investigated in this paper.The operation of membrane was analyzed by evaluating sludge volume index (SVI),modified fouling index (MFI),and membrane resistance (Rt),respectively.The results showed that SVI,MFI,and Rt increased with the accumulation of EPS,and membrane fouling aggravated with the increase of EPS,this illustrated that the content of EPS had a direct influence on SVI,MFI,Rt and membrane fouling.The consequences could offer a simple method to monitor the concentration of EPS by analyzing SVI,MFI,or Rt.
