(57) [Summary] Conventionally, photocatalytic activity for decomposing organic compounds or inorganic compounds has been low. An odor gas (B) and ozone (A) are blown into a photocatalyst solution (C) in a processing vessel (1), which is a processing apparatus for decomposing an organic compound or an inorganic compound, and a UV lamp (3) serving as an excitation light source is emitted from inside the processing vessel (1). To decompose odor gas B and the like efficiently. |
