<p>PURPOSE:To provide an adsorption process wherein gas containing volatile organic substances, particularly waste gas into which volatile organic chloride compounds or compounds contained in city water, waste water, etc., are discharged by stripping are made harmless using adsorbents at low cost in a simple manner. CONSTITUTION:Volatile organic substances contained in raw water 1 are adsorbed on adsorbents 7 or the raw water 1 is subjected to stripping 2 and volatile organic substances 6 discharged therefrom are adsorbed on the adsorbents 7, and the adsorbed components are desorbed from the adsorbents by means of regeneration gas 11 to transfer said components into the gas to regenerate the adsorbents. The volatile organic substances transferred into the gas 10 are decomposed at a and thereafter the gas for decompisition process is circulated as regeneration gas 11 for the adsorbents, and for decomposing the volatile organic substances, a pyrolysis process or photolysis process can be employed.</p> |
