摘要
絮凝剂作为一类能使悬浮液中的细微颗粒凝聚,沉降的水处理药剂,被广泛应用。随着科学技术的发展,絮凝剂的种类也越来越多,功能也越来越完善,具体。综述了最近10几a来国内外对絮凝剂的研究与发展以及国内外在这个领域内所取得的进展及发展趋势。
Abstract The applications of the flocculants at home and abroad were reviewed, including the graft copolymerization, hydroxyl etherification, the variety of alkenes and alkyl halogenated ammonium, etc. Especially, the synthetic nonpoisonous cationic high polymer flocculants and the modified cationic high polymer flocculants from natural high polymer such as the starch were summarized and discussed. The development of the flocculants was predicted and their development trends were analyzed and predicted.
