摘　　要：为提高印染废水的絮凝脱色效果,减轻水处理药剂对环境的影响,将壳聚糖与聚合铝铁复配技术用于活性染料染色废水的脱色处理。结果表明:与单独使用聚合铝铁作混凝剂相比,具有脱色率高、处理时间短、出水CODCr浓度低、铝盐用量少、废水的可生化性好等特点。To improve printing and dyeing wastewater decolofization effect of flocculation,and to reduce the environmental impact of water treatment chemicals, PAFC and chitosan polymer technology were applied for deeolorization of reactive dye wastewater treatment. The results show that with PAFC alone in comparison, the technology have good characteristics of high rate of decolorization,short processing time,low CODCr values of outlet, less aluminum and good biodegradability of the wastewater.
