用羧甲基壳聚糖(CMCTS)复合聚合氯化铁(PFC)对相对分子质量较小的活性染料模拟废水进行脱色处理.结果表明,引入PFC作为助凝剂的脱色效果优于单纯使用CMCTS.采用此复合絮凝剂处理染料废水的最佳条件为pH=5,CMCTS和PFC的投加质量浓度分别为90 mg/L和2 mg/L.在此优化条件下,染料废水的脱色率可达93.8%,COD去除率达89.6%.
用羧甲基殼聚糖(CMCTS)複閤聚閤氯化鐵(PFC)對相對分子質量較小的活性染料模擬廢水進行脫色處理.結果錶明,引入PFC作為助凝劑的脫色效果優于單純使用CMCTS.採用此複閤絮凝劑處理染料廢水的最佳條件為pH=5,CMCTS和PFC的投加質量濃度分彆為90 mg/L和2 mg/L.在此優化條件下,染料廢水的脫色率可達93.8%,COD去除率達89.6%.

The application of composition flocculants of carboxymethyl chitosan (CMCTS) and polyferric chloride (PFC) to the decolorization of dyeing wastewater has been carried out. The dye used is reactive dye with small molecular weight. The results show that the effect of using PFC as coagulant aid is better than that of using CMCTS alone. The optimal conditions are as follows:pH=5 ,CMCTS dosage=90 mg/L, and PFC dosage=2 mg/L.Under these conditions, the rate of decolorization could achieve 93.8% and removal rate of COD reaches 89.6%.
