<p>PROBLEM TO BE SOLVED: To provide a method of effectively deodorizing a stench component over a prolonged period of time. SOLUTION: A stench component can be effectively removed over a prolonged period of time by continuously or intermittently spraying the water solution of peroxide hydrogen with contacting active carbon, particularly honeycomb-like active carbon (for example, cell number is 10 to 1,500 cells/inch<2> , BET specific surface area is more than 200 m<2> /g) with gas containing the stench components. The stench components are hydrogen sulfide, mercaptans, sulfides, disulfides, ammonia, amines, aldehydes, and organic acids. Moreover, when deodorization treatment is conducted with honeycomb-like active carbon in a dry state (particularly, a drug carrying honeycomb-like material which carries chemicals such as iodine, inorganic iodide, and bromine) after gas containing the stench components is treated with active carbon having used water solution of peroxide hydrogen, the stench components can be almost perfectly deodorized over a prolonged period of time.</p> |
