An apparatus characterized by including an adsorption treatment chamber fitted with, superimposed one upon another in the direction of gas flow, adsorption frames having an adsorbent capable of adsorbing volatile organic compounds; an adsorbent regeneration treatment chamber equipped with a discharge unit having a high-voltage electrode, an earth electrode and a dielectric; and adsorption unit transfer means capable of transferring adsorption frames disposed upstream along the gas flow into the adsorbent regeneration treatment chamber and transferring any adsorption frames of the adsorbent regeneration treatment chamber downstream along the gas flow. Thus, there is provided an apparatus for volatile organic compound treatment available at low apparatus cost, which apparatus realizes efficient decomposition of VOC without the emission of a large volume of harmful NOx.
