摘　　要：在制备聚合硫酸铁的过程中加入钠化膨润土,成功制备了聚合硫酸铁插层膨润土絮凝剂,并将其用于高浓度有机马铃薯淀粉废水的预处理,效果显著。当原水浓度COD为6 268 mg/L,pH为6.5,温度为20℃时,COD去除率为31.5%。Na-Bent was used as core in preparation of inorganic polymer flocculants,which afford a new kind of solid composite polyferric sulfate（SPFS） for the first time.It was used to pretreat high concentration of organic wastewater,and the potato starch wastewater contained starch,saccharides,protein and other soluble substances.The effect was remarkable.The results indicated that the maximum removal rate of COD was 31.5% when temperature was 20 ℃,pH was 6.5 and COD concentration of raw water was 6 268 mg/L.
