摘　　要：木质素是植物纤维的重要组成和造纸黑液污染的主要成分。改性木质素具有优良的理化特性,可作为水处理剂,具有充分利用资源和高效治理废水的双重意义。对木质素絮凝剂、缓蚀剂、阻垢剂和分散剂等的不同合成方法及应用效果进行了综述,认为木质素水处理剂具有很好的经济效益和发展前景。Lignin is a main component of plant fiber and pollution composition of black liquids of papermaking. Modified lignin is used as water treatment agents for its fine physical and chemical property, which will be important in both resources u- tilization and wastewater disposal. The different modified ways and applied effect of lignin based flocculant, corrosion inhibition agents, and scale inhibition agents and dispersant has been reviewed. It is thought the lignin water treatment agents have wide developmental foreground and economic benefits.
