| 摘 要： | 在MBR处理生活污水的试验中,对投加PAFC的混凝MBR和普通MBR进行了对比,考察膜污染的变化情况.在一个运行周期内,普通MBR胞外聚合物中各组分的增长速率明显大于混凝MBR,在系统运行的60d中,普通MBR膜组件共清洗了2次,分别是在30 d和50 d,混凝MBR膜组件在48 d时清洗了1次.试验结果表明微生物中胞...

| Abstract: | Using MBR to treat domestic wastewater,the situations of membrane fouling in the MBR with added PAFC and common MBR were compared,and the variation of them were investigated at the same time.In a running period,the growth speed of the components of extracellular polymeric substances in the common MBR was obviously higher than that in the MBR with added coagulant;during the 60-day operation,the membrane module in the common MBR was cleaned twice on the 30th day and the 50th day respectively;meanwhile,the membrane module in the MBR with added coagulant was cleaned one time on the 48th day.The test results showed that,membrane fouling was impacted by extracellular polymeric substances;therefore,adding coagulant PAFC could effectively prevent and control membrane fouling. |
