Résumé

In this study, a new type of graft modified flocculant (CS-g-PAD) was copolymerized of AM, DAC and chitosan (CS) by microwave assisted initiation and used for sludge conditioning and dewatering. The effect of reaction conditions on microwave assisted copolymerization was investigated and their optimal values were obtained by orthogonal experiments. The structure and chemical properties of CS-g-PAD were characterized and the results indicated that microwave assisted polymerization can cause the generated side polymer chain of PAD to react with the -NH
