The invention relates to a nickel catalytic packing for Fenton reactors, which belongs to the technical field of wastewater treatment. The nickel catalytic packing for Fenton reactors consists of a carrier and a catalyst loaded on the surface of the carrier, the carrier is natural volcanic rock, which has high mechanical strength and large specific surface area, and can ensure that the packing hasa good fluidized state when in use, and the attached catalyst layer on the surface of the natural volcanic rock is nickel oxide, which has strong catalytic capacity; when the packing is loaded into aFenton tower to treat wastewater, the addition amount of agentia can be greatly reduced, the treatment cost is low, moreover, reaction is rapid, the effluent effect is good, and economic benefit is obvious.
