Beschreibung
Zusammenfassung:	The invention discloses a preparation method of a resin photocatalyst, which specifically comprises the following steps: adding resorcinol, a formaldehyde solution and ammonia water into deionized water, stirring at room temperature to generate white colloidal suspension, and transferring the white colloidal suspension into a stainless steel autoclave for reaction; and cooling to room temperature, washing the obtained solid, and drying to obtain the catalyst. According to the photocatalysis and Fenton technology combined system prepared by the invention, in-situ production of hydrogen peroxide is realized through an organic polymer photocatalysis material, so that the problems of safety and high cost caused by addition of hydrogen peroxide in a traditional Fenton method are solved; in addition, the reduction rate of iron ions is increased by utilizing photo-induced electrons, and meanwhile, the conversion rate of hydrogen peroxide is improved, so that thorough mineralization of organic pollutants is realized.
