<p>PROBLEM TO BE SOLVED: To provide a waste gas treating method capable of sufficiently and surely removing two or more kinds of components to be removed containing in waste gas and excellent in maintenance and versatility. SOLUTION: In the waste gas treating method, organic components 9a and 9b are mainly adsorbed respectively to spherical activated carbons 90a and 90b in adsorbing parts 11 and 21 by successively circulating the waste gas 1 containing the organic components 9a and 9b into adsorbing parts 11 and 21 and successively bringing the waste gas 1 into contact in counterflow with the spherical activated carbons 90a and 90b in the adsorbing parts 11 and 21, and the spherical activated carbons 90a and 90b brought into contact with the waste gas 1 are transferred to desorbing parts 12 and 22, and the organic components 9a and 9b adsorbed respectively to the spherical activated carbons 90a and 90b at the desorbing parts 12 and 22 are desorbed to regenerate the spherical activated carbons 90a and 90b, and regenerated spherical activated carbons 90a and 90b are transported to the adsorbing parts 11 and 21.</p> |
