The invention discloses an integral honeycomb denitration catalyst for a novel WO3 addition technology. The integral honeycomb denitration catalyst comprises, by weight, 4%-8% of WO3, 1%-1.5% of V2O5, 80.5%-90% of TiO2 and 5%-10% of adhesives, wherein the WO3 is added into precursor solution in a catalyst mixing procedure. The honeycomb denitration catalyst is prepared by extruding, drying and calcining materials, has fine chemical stability, heat stability and SO2 oxidization resistance, represents high NH3-SCR (selective catalytic reduction) catalytic activity and a wide active temperature window, has a large specific surface area, high chemical surface activity and fine catalytic effects, and can meet the requirement of flue gas denitration. Compared with the method of leading in WO3 by directly mixing TiO2-WO3 composite powder serving as a raw material, the preparation technology is simpler without relying on imported TiO2-WO3 composite powder, nationally rich titanium resources are made full use of, the cost of the catalyst is reduced, Chinese industrialization progress of the denitration catalyst can be promoted, and popularization of the flue gas denitration technology in China is promoted.
