摘　　要：以竹炭、絮凝剂聚合氯化铝(PAC)及聚丙烯酰胺(NPAM)处理印染废水.结果表明,在处理印染废水时,竹炭与絮凝剂的组合使用效果优于单一组分的处理效果.当竹炭、PAC和NPAM的用量分别为0.15g、680mg/L和6mg/L时,CODCr去除率为91.3%,沉降速率53.47mm/min,处理后水的色度低于2倍.A novel method for treating dye wastewater by combination of bamboo charcoal, inorganic （PAC） and organic （NPAM） flocculants was developed. The results show that the combination treatment with bamboo charcoal and flocculants had better flocculating efficiency for dye wastewater than single flocculant. Under the optimal conditions of bamboo charcoal amount 0. 15 g, PAC amount 680 mg/L and NPAM amount 6 mg/L, CODcr reduction and settling rate were 91.3% and 53.47 mm/min,respectively. Furthermore, the colorrty of treated water was lower than 2.
