摘　　要：对高取代度阳离子淀粉 (DS0 .5 0 1)用作絮凝剂处理废纸脱墨废水进行了研究 ,研究结果表明 ,高取代度阳离子淀粉和无机絮凝剂 (PAC ,硫酸铝等 )及有机絮凝剂 (PAM)复配使用效果最好 ,CODcr去除率可达 84s: This paper studies on the cationic starch with high degree of substitution (DS0.501) used as flocculant dealing with the deinked wastewater.The experimental results show that this kind of cationic starch has a good effect on the deinked wastewater when it uses with the inorganic flocculants(PAC and Al 2(SO 4) 3) and the organic flocculant(PAM),the reduction of the CODcr is about 84%.
