| Abstract: | The extraction of extracellular polymeric substances(EPS) is one key of quantitative analysis of EPS in activated sludge.Optimization of EPS extraction by physics method in activated sludge was investigated for a good extraction process.Extracellular polymeric substances consist of loosely bound EPS(LB) and tightly bound EPS(TB).The influence of ultrasonic time,centrifuging speed and time,shaking time and heating time on LB and TB extraction was studied here,respectively.At last,an optimization scheme of EPS extraction by physics method was generated. |
