摘要
研究了用壳聚糖与丙烯酰胺接枝共聚物做为絮凝剂对印染废水的絮凝处理,并与壳聚糖进行了絮凝效果比较,结果表明,其絮凝效果明显好于壳聚糖,在pH值为5～8范围内,PAC和接枝共聚物浓度分别为400mg·L-1和100mg.L-1时,其对印染废水的色度和COD去除率分别为最好,达到95.92%和76%。
Treating Dyeing wastewater by co-polymerization of chitosan and acrylamide was studied.The comparison of flocculation effect between chitosan and the co-polymerization was made.The results showed that the flocculation effect of the co-polymerization is obviously better than that of chitosan.Under the condition of pH5~8,concentration of PAC and co-polymerization 400mg·L-1 and 100mg·L-1 ,the optimal removal rates of chromaticity were 95 92% and 76%.
