摘　　要：采用复合絮凝剂PAFSC-PAM(聚硅酸铝铁-聚丙烯酰胺)对化工制药废水进行絮凝处理,考察了絮凝剂投加量、反应温度、pH值、快速搅拌转速对絮凝效果的影响。结果表明,复合絮凝剂PAFSC-PAM(质量比为10∶1)的絮凝效果优于PAFSC,在PAFSC-PAM(质量比为10∶1)投加量为160 mg·L-1、反应温度为40℃、pH值为9、快速搅拌转速为250 r·min-1的最佳絮凝条件下,浊度及CODCr去除率分别可达97.9%和87.1%。We used composite flocculant PAFSC-PAM(polyaluminosilicate-polyacrylamide)in the flocculation treatment of chemical pharmaceutical wastewater,and investigated the effects of flocculant dosage,reaction temperature,pH value,and rapid stirring speed on flocculation effect.The results show that the flocculation effect of PAFSC-PAM(mass ratio is 10∶1)is better than that of PAFSC.The removal rates of turbidity and CODCr can reach 97.9%and 87.1%,respectively,under the optimal flocculation conditions as follows:adding 160 mg·L-1 PAFSC-PAM(mass ratio is 10∶1),the reaction temperature is 40℃,the pH value is 9,and the rapid stirring speed is 250 r·min-1.
