摘要
受水处理工程需要的牵引,以聚硅氯化铝、聚硅酸铁及聚硅酸铁铝为代表的三大类新型复合无机高分子絮凝剂的开发研制及应用研究近年来受到格外的关注,取得了不少新成果。综述了该三类絮凝剂制备工艺的改进及在水处理应用的研究进展,讨论了其混凝特性及可能的絮凝作用机理,展望了相应研究与实践的发展趋势,提出了值得继续深入研究的几个问题。
In order to match the requirements of water treatment engineering, considerable attention was paid to develop composite inorganic polymer flocculants during recent years, which are represented by polyaluminum silicate chloride （PAS）, polysilicate ferrite （PSF） and polysilicate ferric aluminum（PAF）. The amelioration of these three kinds of flocculant＇s preparation process and the achievements of their applications on water treatment are reviewed and the possible mechanisms of flocculation action are also discussed respectively. The developing tendency of corresponding researches and practices is prospected. Some useful problems that are worthy of studying are put forward.
