为考察混凝好氧颗粒污泥的絮凝剂聚合氯化铝(PAC)、聚丙烯酰胺(PAM)、壳聚糖的毒性，通过Microtox 实验，利用发光细菌法检测它们的生物毒性，结果表明：PAC、PAM、壳聚糖的15min-EC50值分别为10200mg/L、17200mg/L、169400 mg/L.表明三种絮凝剂均不会对微生物产生毒性，均可以用于好氧颗粒污泥的絮凝作用.

In order to investigate the toxicity sludge of polymerization aluminum chloride (PAC),polyacrylamide (PAM),and chitosan,on the coagulation flocculation aerobic granular,through the Microtox experiment,the using luminescent bacteria toxicity test,results show:1 5min-EC50 value of PAC is 10200mg/L,of PAM is 1 7200mg/L,of chitosan is 1 69400 mg/L. Showed that three kinds of flocculants were not toxic to microorganisms,can be use...
