An apparatus for treating a gas containing a substance to be decomposed, comprising:
- adsorption means equipped with an adsorbent for adsorbing the substance to be decomposed;
- steam introduction means for bringing steam into contact with the adsorbent;
- condensation means for obtaining a condensed liquid containing the substance to be decomposed from the steam containing the substance;
- a reaction tank;
- condensed liquid supply means for supplying the condensed liquid to the reaction tank;
- hypochlorous acid supply means for supplying a solution containing hypochlorous acid to the reaction tank;
- and
- light irradiation means for irradiating an inside of the reaction tank with light.
A method for treating a gas containing a substance to be decomposed, comprising the steps of:
- (A) bringing a gas containing a substance to be decomposed into contact with an adsorbent to adsorb the substance to be decomposed in the adsorbent;
- (B) bringing steam into contact with the adsorbent in which the substance to be decomposed is adsorbed to shift the substance to be decomposed to steam;
- (C) condensing the steam containing the substance to be decomposed to obtain a condensed liquid;
- (D) introducing the condensed liquid into a reaction tank and mixing the condensed liquid with a solution containing hypochlorous acid;
- and
- (E) irradiating the reaction tank with light to decompose the substance contained in the condensed liquid.
