摘要
壳聚糖及其衍生物具有其它人工合成絮凝剂无法比拟的安全无毒、对环境友好等诸多优点,可以去除水中颗粒状和溶解性污染物,在水处理中有着广泛的应用。天然高分子聚合物壳聚糖可以处理含重金属离子的工业废水,还可以用于纺织、食品加工、炼油废水的絮凝处理,环境效益显著。对国内外近年来壳聚糖及其衍生物作为絮凝剂和吸附剂在水处理中的应用进行了综述,并探讨了壳聚糖作为绿色水处理剂的未来发展方向。
Chitosan and its derivatives can remove particulates and dissolved contaminant in water treatment processes,which has many advantages comparison with other artificially synthesized coagulation,such as safe,non-toxin and beneficial to the environment.They are applied mostly to the treatment of industrial waste water containing heavy metals,and flocculation treatment such as textile,food processing and oil treatment.Moreover,its environmental benefit is remarkable.The overview of chitosan used as flocculating agent and adsorbent in water treatment processes was gave.Its future developing trend was also discussed.
