PROBLEM TO BE SOLVED: To provide a deodorization treatment apparatus 1 which suppresses the degradation of recovery amount of deodorization rate due to heating treatment succeeding in the time lapse as much as possible and prevents the deodorization rate from lowering too much, in the deodorization treatment apparatus 1 having deodorization treatment means which has gas passage members 23, 24 causing gas to be treated containing organic material to pass therethrough and performs deodorization treatment of the gas to be treated, and deodorization rate recovery means which recovers deodorization rate of the deodorization treatment by subjecting the gas passage members 23, 24 to heating treatment for performing heating into a temperature higher than the temperature upon the deodorization treatment.SOLUTION: Gas to be treated which is heated into a temperature higher than the temperature upon the deodorization treatment is caused to pass through the gas passage member when the deodorization rate is deteriorated to a predetermined value and, thereby, the gas passage member is subjected to the heating treatment and, in the heating treatment succeeding in the time lapse, the heating treatment temperature for the gas passage member is set higher than that in the preceding heating treatment. |
