Abstract: PURPOSE: An electro-activated catalyst oxidation apparatus for treating odor gas and an oxidation method thereof are provided to solve a current efficiency degradation problem of an electrolyte cell caused by electro-deposition and a process efficiency degradation problem of an electro-activated catalyst oxidation system for treating odor gas. CONSTITUTION: An electro-activated catalyst oxidation device for treating odor gas comprises an electrolyte cell(10) including a positive electrode chamber in which an electro-activated catalyst is oxidized during an electrochemical oxidation process, a negative electrode chamber in which a negative electrode solution is reduced as electrons are received from the positive electrode chamber, and a barrier layer(13) disposed between the positive electrode chamber and the negative electrode chamber; a negative electrode solution storage tank(30) in which the negative electrode solution is stored, and the stored negative electrode solution is circulatory-supplied to the negative electrode chamber of the electrolyte cell; a positive electrode solution storage tank(20) in which a positive electrode solution is stored, and the stored positive electrode solution is circulatory-supplied to the positive electrode chamber of the electrolyte cell; and a heat exchanger(50) for maintaining a constant temperature of the positive electrode solution in the positive electrode solution storage tank. A sulfuric acid or methane sulfonic acid aqueous solution including an electro-activated catalyst can be used as the positive electrode solution or the negative electrode solution. An electro-activated oxidation apparatus for treating odor gas and an oxidation method thereof are provided to solve problems including current efficiency degradation of the electrolyte cell caused by electric deposition and process efficiency degradation of an electro-activated catalyst oxidation system for treating odor gas.
