| Abstract: | 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. |
