摘　　要：木质素是植物纤维的重要组成和构成造纸黑液污染的主要成分,来源丰富,理化特性良好。将其改性后作为絮凝剂,具有充分利用资源和高效治理废水的双重意义。该文对木质素阳离子型、阴离子型及两性型絮凝剂的不同改性方法及应用效果进行了探讨,认为木质素絮凝剂的研究利用具有很好的经济效益和发展前景。Lignin is abundant because it is a main component of plant fiber and pollution composition of black liquids of papermaking. Modified lignin is used as coagulant to treat wastewater, which would be important in both resources utilization and wastewater disposal, for its fine physical and chemical property. In this paper, different modified ways and applied effect of cationic, anionic and amphoteric lignin based floeculants were investigated. It has been thought to be of great significance to study its application because it can improve the value of lignin and reduce the pollution of papermaking. The application of lignin could have wide application foreground and economic benefits.
