摘　　要：用自制的新型复合絮凝剂处理印染厂印染废水 ,研究了废水的pH值、处理时间、搅拌强度、絮凝剂加入量等因素对处理效果的影响。在最佳工艺条件下 ,可使色度去除率达到 90 %以上 ,CODcr去除率达到 80 %以上 ,且工艺流程简单 ,容易操作 。A method is developed to treat dyeing wastewater with a new kind of self-prepared flocculant, it is pointed out that effects of factors such as pH of wastewater, time of treatment, agitation intensity and add amounts of flocculant on treat purpose. In the optimum technology condition, over 90 % of colority are removed, over 80 % of CODcr are removed. It's a simple technological process and easy to operate, the effective advantages are obtained.
