An oxidation treatment method of the present invention includes the step of bringing a solution having an ozone concentration of 120 to 500 mg/L into contact with a substance to be treated made of a combustible substance, thereby subjecting the substance to be treated and the surface thereof to an oxidation treatment. An oxidation treatment apparatus of the present invention includes: a dissolving means that dissolves an oxygen-ozone mixed gas in a fluorine-based solvent to form mixed fluid; an undissolved gas removal means that removes an undissolved gas from the mixed fluid to form a solution; and an oxidation treatment means that brings the solution into contact with a substance to be treated made of a combustible substance, thereby subjecting the substance to be treated and the surface thereof to an oxidation treatment.

Oxidation treatment method and oxidation treatment apparatus

A reaction device having improved temperature control precision and reduced usage of heat transfer medium. The device includes a heat transfer medium circulation tube in contact with an outer wall of a reaction vessel containing a reaction liquid. The device has an inlet for the liquid heat transfer medium at the lower end portion of the heat transfer medium circulation tube, and an outlet for the heat transfer medium. Gaps between the heat transfer medium circulation tube and the reaction vessel outer wall include a filler in which a liquid can flow inside the filler. The outlet is formed so that the liquid heat transfer medium is discharged toward the filler. A member presses the heat transfer medium circulation tube against the outer wall of the reaction vessel. An outer vessel hermetically covers the outer circumference of the reaction vessel.
