摘　　要：无机高分子多阳离子铁系絮凝剂是铁盐等金属离子在水解过程中的中间产物与溶液中带负电荷的溶胶粒及不同阴离子的结合产物。介绍了无机高分子多阳离子絮凝剂中铁系絮凝剂的制备方法,包括聚磷硫酸铁絮凝剂、聚硅铁絮凝剂、聚硅铝铁絮凝剂、聚氯化铝铁絮凝剂,以及这些絮凝剂在印染废水、造纸废水、油田废水、食品工业废水、医药工业废水处理中的应用现状,并对今后的研究方向提出了建议。Ferrite series inorganic polymer cationic flocculants are the combination product of intermediates in the hydrolysis of metal ions （iron ion, etc.） with negative charge sol particles and different anion. In this paper, the preparation methods of ferrite series inorganic polymer cationic flocculants were introduced, including poly phosphate ferric sulfate flocculant, polyferric silicate flocculant, polysilicate aluminum ferric flocculant, polymeric aluminum-ferric chloride flocculant. Application of these ferrite series inorganic polymer cationic flocculants in treatment of wastewater including dyeing wastewater, papermaking wastewater, food industry wastewater and pharmaceutical wastewater was discussed. At last, the future research direction of preparation method was proposed.
