Abstract: The present disclosure belongs to the field of water treatment, and specifically relates to a positively charged quaternary ammonium salt polymer catalyst and its preparation method and an application thereof. The catalyst provided by the present disclosure is prepared from a positively charged quaternary ammonium salt precursor through polymerization and anion exchange, wherein the positively charged quaternary ammonium salt precursor is the reaction product of an acrylate and a haloalkane; the acrylate is selected from the group consisting of dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, ethyl 3-(dimethylamino)acrylate and a mixture thereof; the haloalkane is selected from the group consisting of bromoundecane, bromododecane, bromotetradecane, bromohexadecane, bromoeicosane, chlorododecane, chlorotetradecane, chlorohexadecane, and a mixture thereof. The catalyst provided by the present disclosure has good stability and antibacterial property, can efficiently and selectively catalyze peroxide to degrade organic pollutants, which has important practical significance for removing wastewater rich in organic pollutants, and it has a wide range of application prospects in water pollution control and water environment restoration.
