| 摘 要： | 研究了用酸浸的粉煤灰和鼓风炉铁泥作原料制备PBS混凝剂并用于造纸废水的处理结果表明．PBS混凝剂与聚硅酸铝（PSA）絮凝剂配合处理造纸废水．在pH值为7．0、混凝剂的投加量为60mg／L的条件下，SS、CODcr和色度的去除率分别为92．4％．85．2％和91．6％与Al2（SO4）3和FeCl3常规混凝剂相比．PBS混凝剂的混凝沉降性能明显优于常规混凝剂。

| Abstract: | The technological process of treating papermaking wastewater with PBS coagulant made by fly ash in coal-fired thermal power plants and blast furnace iron sludge extracted with a dilute H2SO4 was studied.The results showed that the removing rates of S S,CODCr and colourity in papermaking wastewater was 92.4%,85.2% and 91.6% respectively in the conditions when pH value was 7.0 and dosage of the coagulant was 60mg/L,combined with polysilicate aluminum(PSA) flocculant.In comparison with the conventional coagulants,such as Al2(SO4)3 and FeCl3,the coagulation performance of PBS coagulant was obviously superior to conventional coagulants. |
