Paper Title:
Application of Cationic Starch Graft Copolymer in Flocculating of Wastewater from Bleaching
  Abstract

Corn starch, acrylamide and diallyl dimethyl ammonium were used as the raw materials and ammonium persulfate as initiator, cationic starch graft copolymer was prepared, and then the prepared cationic starch graft copolymer is applied to flocculate wastewater from bleaching. The results show that The flocculation of cationic starch graft copolymer to wastewater from increases first and then decreases after the reach of the peak with the increase of the cationic degree of the cationic starch graft copolymer, addition amount, flocculating temperature and flocculating time. When the cationic degree of the cationic starch graft copolymer is 27.38%, the addition amount is 7.5%, the flocculating temperature is 50°C and the flocculating time is 30min, the flocculation of cationic starch graft copolymer to wastewater is the best. The flocculation of alum/cationic starch graft copolymer is better than cationic starch graft copolymer is used only. Introduction
