PURPOSE:To deodorizes gases to be treated efficiently by injection of ozone at a specified concn. by providing a buffer tower in the fore stage of a deodorozing tower which combines a deodorizer deposited with a bromine compd. and ozone thereby eliminating the fluctuations in the concn. of malodorous components. CONSTITUTION:Gases to be treated which have malodors are introduced into a buffer tower 7 like an arrow A, where the gases contact with the buffer agent 8 in the tower 7 and the concn. of the malodorous components is leveled off. Thereafter the ozone generated in an ozone generator 3 is injected into the gases through an ozone piping 6 like an arrow B, then the gases after the buffering contg. a prescribed concn. of ozone contact with a deodorizer 5 deposited with a bromine compd. in a deodorizing tower 4, whereby the gases are deodorized. |
