    • PROBLEM TO BE SOLVED: To provide a method for decomposing an organic halogen compound which can reduce consumption of an oxidant used for an oxidative decomposition process carried out after an anaerobic dehalogenation process.
      SOLUTION: The method for decomposing the organic halogen compound, which decomposes the organic halogen compound contained in an object to be processed, is provided. The method includes an anaerobic dehalogenation process of pouring an accelerator accelerating a decomposition of the organic halogen compound by anaerobic microorganisms into the object to be processed and of replacing a part of halogen elements of the organic halogen compound by non-halogen elements with the anaerobic microorganisms; a recovering process of recovering the accelerator poured into the object to be processed after the anaerobic dehalogenation process; and an oxidative decomposition process of pouring the oxidant into the object to be processed after the recovering process, and of oxidative-decomposing the organic halogen compound.
