摘　　要：重金属污染物不能自然降解,给人类健康和生态环境造成了严重威胁,化学絮凝法已被广泛应用于重金属废水的处理。天然高分子絮凝剂具有无毒、可生物降解等优点,其在处理重金属废水方面有着极大的优势。综述了淀粉、壳聚糖、植物胶、海藻酸钠、纤维素等多糖类天然高分子絮凝剂在重金属废水处理中的应用进展。Heavy metal pollutants cannot be degraded naturally,which poses serious threat to human health and ecological environment.Chemical flocculation has been widely used in the treatment of heavy metal wastewater.Natural polymer flocculants have great advantages in treating heavy metal wastewater due to their nontoxic and biodegradable properties.The application of starch,chitosan,vegetable gum,sodium alginate,cellulose and other polysaccharide-flocculants in the treatment of heavy metal wastewater is reviewed.
