PURPOSE:To provide a treating method by which the removal effeciency of alcohols is increased and, besides, the breakthrough time of an absorbent is lengthened in a purifying treatment of gaseous solvent in gas. CONSTITUTION:In a method for treating alcohols contg. gaseous organic solvent 11 in gas, after alcohols are absorbed in a scrubber 6, the liquid absorbent is decomposed by aerobic-biological treatment 7 and gaseous solvent other than alcohols is subjected to absorptive treatment 1, 2 by an adsorbent. In the method, any of the biological treatment and the adsorptive treatment may be preceded by each other. |
