Abstract:

In this paper, the performance of flocculation and purification of agent CGP- B have been studied in detail under various conditions, which is a kind of natural graft- copolymerised high polymer agent, as far as the flocculation of high density surfactant wastewater is concer ned. Exper iments result illustrates adding CGP-B and PAC at the same time is superior to that of adding PHP and PAC at the same time, flake setting rate is faster and suitable range of pH is wider, COD elimination rate is higher. So, CGP- B is a new flocculant with good performance.

摘要：

以高浓度表面活性剂废水为处理对象，详细研究了接枝共聚型天然高分子絮凝剂CGB-A在不同条件下的絮凝净化性能。实验结果表明，药剂CGB-A与聚合氯化铝(PAC)配伍使用处理效果明显优于PAC与阴离子聚丙烯酰胺(PHP)配伍使用效果，产生的絮体沉降速度快，适用的pH值范围宽，COD_Cr去除率高。因此，药剂CGB-A是一种絮凝性能好的新型絮凝剂。
