The invention discloses an integral dioxin removing catalyst, which is prepared by coating a catalyst coating constituted by V2O5, WO3 and TiO2 onto honeycomb ceramic of 30-600 meshes serving as a carrier. The catalyst is a vanadium-tungsten-titanium system catalyst, and has a better anti-poisoning effect on HCl and SO2 in waste incineration tail gas; the honeycomb ceramic of 30-600 meshes is taken as the carrier, and has higher adaptability to flue gas dust due to a regular pore canal, so that industrialization and engineering minimization are realized easily, larger reaction surface area is provided, high reaction efficiency can be kept at high space velocity of flue gas, and the investment cost of the catalyst is reduced; catalyst active ingredients are loaded onto the carrier by using a coating process, so that operation is convenient, and the production efficiency is high; in the preparation process of the catalyst, an inorganic pore forming agent is added, so that void ratio is increased, the contact area between a reactant and the catalytic active ingredients is increased, and the catalyst activity is increased; the inorganic bonding agent is added, so that the bonding performance between the coating and the carrier is enhanced, and the coating firmness is improved; in the presence of the catalyst, the decomposition conversion rate of dioxin is over 95 percent at the temperature of 160-180 DEG C.
