Abstract

PURPOSE: To cut off consumption of activated carbon in a posttreatment process, and to deodorize washed waste water in refining a gas produced from a sewage disposal plant from a reductive malodorous gas, by using a gas containing unreated ozone gas obtained in ozone deodorzation of the water to be treated.
CONSTITUTION: Reductive malodorous component-containing gas 1 is sent to main deodorization apparatus 3 together with unreacted ozone containing gas sent from piping 2. This gas mixture is passed through first scrubber 5, second scrubber 11, third scrubber 21 to remove hydrogen sulfide, methyl mercaptan, methyl sulfide, ammonia, methyl amine, or the like malodorous components in the malodorous gas. This gas is passed through activated carbon decomposition tower 32 and released as a harmless odorless gas. On the other hand, the polluted water to be treated is introduced into ozone reaction tower 40 to treat it by oxidation. The resultant foaming substance is introduced into defoaming tower 48 together with the unreacted ozone containing gas. to remove the foam. The unreacted ozone containing gas from tower 48 is passed through piping 2 and introduced into main scrubber 3.
