PROBLEM TO BE SOLVED: To provide a method for treating an organohalogen compound by which the treatment is smoothly carried out without risks of increase of a distillation cost and loss of metallic sodium, and without the risk of blocking of solution sending by an alkali metal salt formed by the reaction of an alkali metal with the organohalogen compound; and to provide an apparatus for treating the compound. SOLUTION: The method for treating the organohalogen compound comprises a reaction step for mixing a liquid to be treated, formed by dissolving the organohalogen compound in a hydrocarbon solvent, with the alkali metal to react the organohalogen compound with the alkali metal and to decompose the organohalogen compound to afford a reacted and treated liquid, a hydration step for feeding the reacted and treated liquid to a hydration vessel without distillation and adding water to the reacted and treated liquid in the hydration vessel to extract the alkali metal halide formed by the reaction with the water, an oil-water separation step for separating and removing the water from the reacted and treated liquid having passed the hydration step in the oil-water separation vessel, and a distillation step for distilling the reacted and treated liquid having passed the oil-water separation step in a distillation vessel to recover the hydrocarbon solvent.
