The invention discloses a method for preparing an ozone catalyst from hot-rolled oil sludge and Fenton silt. The method comprises the following steps: drying and crushing the Fenton silt; acid is added into the hot-rolled oil sludge, stirring is conducted for a set time, and after the set time is over, smashed Fenton silt is added and evenly mixed; granulating the uniformly mixed material to obtain a granular material, and drying the granular material; and in an inert environment, carbonizing the granular material to obtain the ozone catalyst, the problems of reduction, recycling and harmlessness of the hot-rolled oil sludge and the Fenton silt are effectively solved, and meanwhile, the ozone catalyst with low production cost and excellent catalytic performance is obtained. 本发明公开了一种利用热轧油泥及芬顿沉泥制备臭氧催化剂的方法，包括：烘干并粉碎所述芬顿沉泥；在所述热轧油泥中加入酸并搅拌设定时间，所述设定时间结束，将粉碎的芬顿沉泥加入并混匀；混匀后的物料经造粒得到粒状物，烘干所述粒状物；在惰性环境下，将所述粒状物进行炭化处理后得到臭氧催化剂；不仅有效解决热轧油泥及芬顿沉泥的减量化、资源化及无害化的问题，同时一举两得地获得了低生产成本、催化性能优良的臭氧催化剂。
