▎ 摘  要

NOVELTY - A sludge advanced treatment catalyst comprises 20-40 pts. wt. graphene oxide, 4-8 pts. wt. calcium oxide, 3-5 pts. wt. wax, and 0.6-0.8 pts. wt. ammonium nitrate. The wax is solid at room temperature. The calcium oxide, ammonium nitrate and wax are embedded in graphene oxide interlayer structure. USE - The catalyst is used for advanced treatment of sludge. ADVANTAGE - The catalyst is environment-friendly and can be dispersed in the sludge in use process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the catalyst by heating wax and 20-40 times solvent, stirring and dispersing, adding calcium oxide and ammonium nitrate, and continuously ultrasonically dispersing to obtain dispersion liquid; and heating and mixing graphene oxide and dispersion liquid, dispersing, cooling and standing, filtering, and vacuum freeze-drying.
