PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing an ozone-containing aqueous solution which can be used for oxidative decomposition of organic matter or for disinfection, in which a sodium salt of an oxo acid of chlorine, ozone, and a hydroxy radical coexist, and in which ozone can be stored for a long period of time by retaining ozone in the aqueous solution, and the ozone-containing aqueous solution.SOLUTION: An aqueous solution in which ozone, a sodium salt of an oxo acid of chlorine, and a hydroxy radical coexist is prepared by making a sodium hypochlorite aqueous solution and ozone react with each other. Also a production apparatus 10 of an ozone-containing aqueous solution is equipped with a reaction tank 12, a raw material aqueous solution supply part 14 to supply the sodium hypochlorite aqueous solution or a sodium chloride aqueous solution to the reaction tank, and an ozone supply part 16 to generate ozone, to supply the generated ozone to the reaction tank 12, and to make the sodium hypochlorite aqueous solution or the sodium chloride aqueous solution react with ozone. |
