摘要： PROBLEM TO BE SOLVED: To effectively use a catalyst by treating an aromatic organic chlorine compound contained in waste gas with the catalyst in the range of waste gas linear velocity found by a specific equation obtained from the quantity of waste gas to be treated and the quantity of the catalyst to be used in the treatment of the waste gas for decomposing and removing the chlorine compound. SOLUTION: The aromatic organic chlorine compound denotes polychlorodibenzodioxin, polychlorodibenzofuran or the like. As catalyst for decomposing the aromatic organic chlorine compound, a catalyst consisting of particularly Ti oxide and V, W is preferable. At the time of decomposing and removing the aromatic organic chlorine compound contained in the waste gas with the catalyst, the treatment is carried out at the optimum waste gas linear velocity obtained from the flow rate of waste gas to be treated and the quantity of the catalyst to be used by using the equation (in the equation, S=a/b, (a) represents a flow rate (Nm3/hr) of the waste gas to be used and (b) represents a quantity of the catalyst to be used). The ratio of the flow rate of the waste gas to be treated to the quantity of the catalyst to be used is preferably about 100-10,000, further preferably 500-6,000.
