Abstract
An effluent treating method, comprising the steps of: vaporizing effluent containing chlorine-based organic matter and producing vaporized gas containing chlorine-based organic gas; reacting said vaporized gas with photocatalytic material, with irradiating ultraviolet light, and decomposing the vaporized gas; and absorbing, adsorbing, or neutralizing the reacting step. The treatment is therefore efficiently conducted and discharge of secondary products such as chlorine-based gas can be suppressed.
