接枝共聚型天然高分子絮凝剂的性能及应用研究

THE PERFORMANCE AND APPLICATION STUDY OF A NATURAL GRAFT-COPOLYMISED HIGH POLYMER FLOCCULANT

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，ＣＯＤＣｒ去除率高。因此，药剂ＣＧＢ—Ａ是一种絮凝性能好的新型絮凝剂。

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 concerned. Experiments 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.
