PROBLEM TO BE SOLVED: To provide a waste gas treating method which is capable of improving the adsorption rate of organic chlorine compounds by using photocatalysts of a small particle size and is capable of improving the decomposition efficiency, and an apparatus for the same. SOLUTION: Waste gases 4 to be treated are brought into contact with photocatalysts 6 in a mixing device 1 and, after the organic chlorine compounds in the waste gases are adsorbed to the photocatalysts, the photocatalysts 6 are separated from the waste gases by a bag filter 2 and the photocatalysts 6 are introduced into a photocatalyst cracking device 3 where the photocatalysts are fluidized by gases 17 for flowing and the photocatalysts 6 in the photocatalyst cracking device 3 are irradiated with light and the organic chlorine compounds adsorbed at the photocatalysts 6 are cracked and removed by the oxidation effect of the photocatalysts 6 manifested by this irradiation. |
