Description of the Related Art Ozone has a strong oxidizing ability and decomposes to generate active oxygen, so that it is widely used in a wide range of fields such as deodorization, sterilization and bleaching. However, the ozone remaining after the ozone treatment of the target substance is released into the atmosphere in an unreacted state, which not only causes an unpleasant odor but also contributes to the generation of photochemical smog. The allowable concentration of ozone is 0.1 ppm, and at a high concentration, it causes irritation to the respiratory system and is harmful to the human body. Therefore, it is necessary to remove excess ozone and detoxify these ozone treatment devices.
