<p>PROBLEM TO BE SOLVED: To inexpensively and effectively adsorption remove a malodorous material in a gaseous body to be treated by introducing the gaseous body to be treated containing the malodorous material into a treating solution composed of water, oil or a solution of water and oil, which contains >=2 kinds of surfactants having different HLB from each other to adsorption remove the malodorous material. SOLUTION: The gaseous body G to be treated such as a waste oil or the like H generated in a malodor generating vessel 10 is successively introduced into a 1st, a 2nd and a 3rd scrubber 11-13 by a suction fan 15 to remove the malodorous material and each scrubber 11-13 houses each surfactant solution 21-23 composed of water, the oil or the solution of water and the oil, which contains >=2 kinds of surfactants having different HLB from each other, as the treating solution. In such a case, the difference of the HLB of each surfactant in each surfactant solution 21-23 is preferably >=1.0. And the gaseous body G to be treated is successively treated in multistage by passing through the 1st scrubber 11 to the 3rd scrubber 13 to remove the malodorous material and discharged from an exhaust port 19 as a odorless gaseous body.</p> |
