In order to solve the shortcomings of a single flocculant, inorganic–organic hybrid flocculant SiO2–CTS–DMDACC was successfully prepared by grafting copolymerization chitosan (CTS), dimethyl diallyl ammonium chloride (DMDACC), and silicon dioxide (SiO2). The performance in treating papermaking wastewater investigated, mechanism flocculation process analyzed. results showed that crystallinity reduced due introduction DMDACC SiO2. water solubility thermal stability with rough porous structure were enhanced. enhanced cationic properties CTS–DMDACC compared CTS. addition, CTS–DMDACC, SiO2 increased viscosity SiO2–CTS–DMDACC. experimental treatment effect CTS:SiO2:DMDACC 1:2:4 best better than CTS at pH 7 for wastewater. removal rates turbidity, COD, NH4+-N 99.43%, 82.92%, 78.43%, respectively. revealed charge neutralization main SiO2–CTS–DMDACC, adsorption bridging net sweeping played supplementary roles
