The application provides a composite material for sludge dewatering, a preparation method thereof and a sludge dewatering conditioner. The composite material for sludge dewatering comprises magnetic porous carbon and molybdenum disulfide loaded on the magnetic porous carbon, wherein the magnetic porous carbon comprises porous carbon and ferroferric oxide loaded on the porous carbon. The preparation method comprises the following steps: mixing the magnetic porous carbon with a molybdenum source and a sulfur source, and performing a hydrothermal reaction to make the molybdenum source and the sulfur source react to generate molybdenum disulfide; after the reaction is completed, performing solid-liquid separation, collecting the solid product, and calcining the solid product under an inert atmosphere at 350-450 DEG C to obtain the molybdenum disulfide magnetic porous carbon composite material; wherein the magnetic porous carbon comprises porous carbon and ferroferric oxide loaded on the porous carbon; and the composite material for sludge dewatering can construct a molybdenum disulfide magnetic carbon-based composite material with a large specific surface area, high catalytic activity and high universality, and the composite material can improve the sludge dewatering performance.
