PROBLEM TO BE SOLVED: To provide a method for treating an organic chlorine compound-containing aqueous solution which comprises a method for regenerating an adsorbent, such as activated carbon, to which organic chlorine compounds are adsorbed by a simple means without using a large-sized device, such as a regeneration furnace, when treating the aqueous solution contaminated by the organic chlorine compounds. SOLUTION: This method for treating the organic chlorine compound-containing aqueous solution comprises a process where the aqueous solution containing the organic chlorine compounds, such as trichloroethylene, is introduced into an adsorption column 10 to adsorb the organic chlorine compounds to the adsorbent 11, such as granular activated carbon, a process where an acetic acid solution prepared beforehand in an acetic acid preparation tank 30 so that its concentration becomes≥40 vol.% is introduced into the adsorption column 10 to desorb the organic chlorine compounds adsorbed to the adsorbent 11, and a process where the acetic acid solution containing the desorbed organic chlorine compounds is introduced into an ozone reaction tank 20 to decompose the organic chlorine compounds in the acetic acid solution by ozone.
