The invention discloses recovery process of honeycomb type selective catalytic reduction (SCR) waste catalyst. The process includes the following steps: a, preprocessing the SCR waste catalyst and leaching at the high temperature and under high pressure; b, adding hydrochloric acid into leaching liquid, adjusting pH, and removing impurities; c, adding hydrochloric acid into the leaching liquid, reacting, calcining and preparing rutile titanium dioxide; d, preparing ammonium paratungstate; e, preparing ammonium metavanadate; and f, recycling and treating waste water. Main products of ammonium paratungstate, ammonium metavanadate and rutile titanium dioxide obtained in the process are high in purity and recovery rate. By-products of silicon magnesium slags, salty mud, high-concentration sodium chloride liquid and barium sulfate dregs are high-purity harmless useful goods. The process is free of harmful secondary pollutant emission, environment-friendly and capable of circulating, has high economical and social benefit and is practicable.
