摘　　要：研究了硫酸铝、季铵盐类有机絮凝剂、复配絮凝剂对印染废水的脱色效果,探讨了加入量、复配比对脱色效果的影响。结果表明:采用无机有机复配絮凝剂处理印染废水的絮凝脱色效果较好,最优实验条件为:无机与有机絮凝剂复配比为6:4,加入量为(96+64)/(mg/L),该条件下印染废水脱色率可达98.5%,COD去除率达81.68%。The decolorization effect of aluminum sulfate,quaternary ammonium salt organic flocculants,and composite flocculants on printing and dyeing wastewater was studied,and the effects of addition amount and composite ratio on the decolorization effect were explored.The results show that the flocculation and decolorization effect of using inorganic organic composite flocculants to treat printing and dyeing wastewater is good.The optimal experimental conditions are:the ratio of inorganic and organic flocculants is 6:4,and the addition amount is(96+64)/(mg/L).Under these conditions,the decolorization rate of printing and dyeing wastewater can reach 98.5%,and the COD removal rate can reach 81.68%.
