摘要：

采用反相悬浮法制备改性壳聚糖磁性微粒絮凝剂，并探讨了该絮凝剂对造纸废水的絮凝作用，着重考察了絮凝剂的投入量、体系pH值、搅拌速度、搅拌时间、沉降时间对造纸废水中COD去除率的影响。结果表明在最佳条件下该絮凝剂对造纸废水的COD去除率可达56.52%，且具有投入量少、pH应用范围广、絮凝时间和沉降时间短的优点，说明改性壳聚糖磁性微粒作为絮凝剂对造纸废水的处理切实可行。

Abstract:

A new type of flocculant which modified chitosan magnetic microscopic particles were prepared by inverse suspension method in Lab.And based on this, the flocculability experiment on papermaking wastewater was carried out . Relations of flocculability with the dosage of flocculant, pH, agitation speed, agitation time and settling time were discussed. The results indicate that the removing efficiency for CODCr are 56.52% under the best conditions.It also had some advantages such as little dosage, wide pH and shorter settling time.So it is a good method for treatment of pulp and paper wastewater by modified chitosan magnetic microscopic particles.

Key words: Modified chitosan Magnetic particles Wastewater of pulping and papermaking
