Abstract:
The composite flocculant CTS-PFC has been obtained by means of embedding in chitosan(CTS)for modifying polyferric chloride(PFC). It can be applied to the treatment of urban sewage,and the flocculation effect of it is investigated. The experiments show that the flocculation effect is the best,decolorization rate 93.5% and COD removing rate 49.7%,when m(CTS):m(PFC)is 1:1,optimal dosage of CTS-PFC 1.0 g/L,and pH of wastewater 6-7.

摘要： 通过将壳聚糖（CTS）嵌入的方式改性聚合氯化铁（PFC），得到复合型絮凝剂壳聚糖-聚合氯化铁（CTS-PFC），将其用于城市污水处理，对其絮凝效果进行了考察。实验表明：当m（CTS）：m（PFC）为1：1，CTS-PFC最佳投加量为1.0 g/L，废水的pH为6~7，絮凝效果最佳，脱色率为93.5%，COD去除率为49.7%。
