| abstract | (57) [Summary] [Structure] A method for treating wastewater containing sulfide-based malodorous substances such as hydrogen sulfide, methyl mercaptan, methyl sulfide and methyl disulfide in the presence of a transition metal compound and hydrogen peroxide. The method for treating wastewater uses at least an iron compound and a vanadium compound as the transition metal compound. [Effects] According to the present invention, a sulfide-based malodorous substance can be removed without being affected by a coexisting substance such as methanol that is relatively easily oxidized, and it can be easily discharged out of the system as treated water. Conventional treatments such as biological activation treatment can be performed. |
