摘要 研究了3种絮凝剂氯化铁(FeCl_3)聚合氯化铝(PAC)壳聚糖(Chitosan)对膜生物反应器内活性污泥理化性质的影响。结果表明,3种絮凝剂对活性污泥均有一定影响,其中絮凝剂PAC的效果最佳。PAC使活性污泥的污泥比阻减少80%,平均粒径增大了53%,上清液TOC含量降低了63%,EPS含量增加平缓。建议采用PAC改善活性污泥理化性质,以减缓活性污泥对膜的污染速率,延长膜的使用寿命。 Impact of three types of flocculants(FeCl_3,PAC,Chitosan) on physical and chemical properties of activated sludge in MBR was tested.The results showed that three kinds of flocculants had significant effects on activated sludge,PAC is the most suitable coagulant to avoid membrane blocking.When PAC was using,specific resistance of sludge could be reduced by 80%,the average diameter of sludge floc increased by 53%,supernatant TOC concentration decreased by 63%,and EPS increased slowly,which illustrated that PAC had a significant impact on the phycical and chemical properties of the activated sludge,the use of PAC in MBR could be help for reducing the membrane fouling.
