摘　　要：通过单因子试验和正交试验研究了无机聚铁盐絮凝剂与壳聚糖复配使用对海水的净化效果。结果表明：壳聚糖与聚合氯化铁的复合絮凝效果优于壳聚糖与聚合硫酸铁的；影响海水净化效果的最主要因素为聚合氯化铁投加量，其次是壳聚糖投加量，pH值无显著影响。当聚合氯化铁投加量为20mg／L、壳聚糖投加量为4mg／L、pH值为6～7时，复合絮凝剂对海水的净化效果最佳，对浊度和UV254的去除率分别为93．1％和35．7％。Seawater purification by inorganic ferric sahs/chitosan composite flocculants was stud- ied by single-factor experiment and orthogonal experiment. The results showed that PFC/chitosan com- posite flocculant had better flocculation efficiency than PFS/chitosan. The most important factor for sea- water purification was PFC dosage, followed by chitosan dosage. The flocculation pH had no significant effect on seawater purification. When PFC dosage was 20 mg/L, chitosan dosage was 4 mg/L and pH value was 6 to 7, the PFC/chitosan composite flocculant had the best seawater purification effect. The re- moval rates of turbidity and UV254 were 93.1% and 35.7%, respectively
