Abstract
A gas containing bad smell substances and a washing solution for deodorization are fed into a wash tower so as to carry out the deodorization by the gas-liquid contact. An aqueous solution of an alkali bromide and an ozone-containing gas are fed into a bubbling vessel to produce in active bromine oxide compound. The solution containing the active bromine oxide compound is added to the washing solution and the bad smell gas is washed with the washing solution in the wash tower. The effect of deodorization is improved by the function of the bromine oxide compound and an amount of ozone discharged out of the system is decreased.
