PROBLEM TO BE SOLVED: To easily and unerringly remove a harmful gas by making an ozonolysis catalyst effectively act. SOLUTION: The harmful gas removing system prevents as much as possible harmful gas removing performance from degrading in ozonolysis catalysts 401 and 402 by supplying an ozone gas generated in a gas reactor section 13 to the ozonolysis catalyst 402 during a regeneration operation by replacing the position of the ozonolysis catalyst 402 where an ozone gas concentration has decreased due to the harmful gas removal operation with the position of the ozonolysis catalyst 401 where the ozone gas concentration is high when the regeneration operation to regenerate a harmful gas removing function in an ozonolysis catalyst section 14 that has worsened due to the harmful gas removal operation to remove a harmful gas in the atmosphere, differently from the harmful gas removal operation.
