Disclosed is a method and an apparatus for decomposing organic halogen-containing compounds by using ultraviolet radiation. In the decomposition method, the organic halogen-containing compound is dissolved in a solvent to form a liquid, and the liquid is exposed to ultraviolet radiation in the substantial absence of alkaline material. Then, the liquid is treated with an alkaline material. The decomposition apparatus for the organic halogen-containing compound comprises: preparation means for preparing a liquid containing the organic halogen-containing compound and a solvent in which the organic halogen-containing compound can be dissolved; exposure means for exposing the liquid to light radiation of an effective wavelength for initiating decomposition of the organic halogen-containing compound in the substantial absence of an alkaline material; and treatment means for treating the liquid with an alkaline material.
