摘　　要：考察了三种典型无机高分子混凝剂聚合氯化铝(PAC),聚合硫酸铁(PFS),聚合双酸铝铁(PAFCS),以及CaO/LAS摩尔比,助凝剂聚丙烯酰胺(PAM)、温度和pH条件对于强化混凝预处理生物性污染实验室废水效果的影响.实验结果表明:PAFCS处理效果最佳,在最大COD去除率时去除每kgCOD所需的PAFCS用量为PAC和PFS用量的1/6;去除每kgCOD所需的PAFCS药剂成本为PAC或PFS的1/5.确定PAFCS40mg.L-1,CaO/LAS摩尔比0.75,PAM1mg.L-1,温度25℃,pH7为最佳反应条件,此时COD,LAS的去除率可分别达58%和53%,细菌和ATP去除率均为90%以上.The biopollutant laboratory wastewater produced with the development of biological technology has potential threaten for both human health and environment.The effects of several major factors,the coagulants PAC,PFS,PAFCS,the ratio of CaO over LAS(in mole),coagulant aid PAM,temperature and pH,respectively were investigated by single factor experiment.The results show that PAFCS is the best coagulants.To remove a kg COD,the amount of PAFCS needed was one-sixth of PAC or PFS,and the cost of the coagulant was o...
