The chitosan and the cationic monomer(2-methacryloyloxyethyl) trimethylammonium chloride (DMC) were modified by graft copolymerization reaction to prepare a high effective fashion flocculants(CAM). The product structure of graft copolymerization for chitosan and DMC, the Zeta potential, the adaptability analysis of pH values, and soon, would be discussed in the study, and through flocculants tests on the brewery wastewater, the results showed that when the dosage of CAM was 30mg·L~(-1), the removal rate of turbidity reached over 90%. the settling velocity was up to 0.55 cm·s~(-1), the removal rate of COD was over 95%, the flocculation performance of CAM was superior to that of chitosan and PFS.
