摘　　要：本文讨论了新研制的磷酸酯淀粉 /聚胺复合物絮凝剂对脱墨废水的作用效果。主要探讨了磷酸酯淀粉 /聚胺复合物的加入量、废水的 pH值和絮凝时间对絮凝效果的影响。同时考察了磷酸酯淀粉 /聚胺复合物对脱墨废水所含的悬浮物 (SS)、CODcr、浊度的去除性能 ,并与其它几种絮凝剂作了比较。实验结果表明 :磷酸酯淀粉 /聚胺复合物对脱墨废水具有良好的处理效果。The phosphate ester starch/polyamine complex(PESPC),which was prepared in the laboratory,was utilized in the treatment of deinking waste water.The influences of the dosages of PESPC,pH of waste water and flocculating time on the flocculation were investigated,and the optimum conditions were determined.The elimination capacities of PESPC on SS, CODcr and turbidity of the deinking waste water were also studied and compared to other flocculants.The results showed that PESPC was a satisfactory flocculant in deinking waste water treatment.
