摘　　要：传统的除藻化学药剂,往往会造成二次污染。天然物质絮凝剂优势独特,来源天然,安全无毒,此外原料丰富,价格也较低廉,是目前研究的热点。如粘土、壳聚糖、淀粉等通过改性后不仅提高了除藻效率,而且降低了投加量。但是天然物质絮凝除藻的机理还要在实践中继续完善。As using traditional chemical reagents to remove algae always cause secondary pollution, flocculants produced from natural materials has become a research hotpoint for its distinct advantages such as： nautral source; safe and non-toxic, rich raw material and low cost. After the modification, the algae removal efficiencies of some raw materials such as clay, chitosan, starch and so on were improved and the demanded dosage of them were also decreased. However, the mechanism of the flocculation by the flocculants produced from natural materials should be perfected step by step in the future practice.
