PROBLEM TO BE SOLVED: To reduce secondary waste by imperfect oxide, to facilitate maintenance, and to effectively use the secondary waste. SOLUTION: This processing unit performs ashing volume reducing processing by operating generated active oxygen on an ion exhange resin 3 by generating discharge in a discharge vessel 1A by the electromagnetic action of a wound high frequency induction coil 9A by introducing oxygen or plural gases containing oxygen to a reactor vessel 2B containing a processing pan 4 loaded with the ion exchange resin 3. At this time, a gas introducing port 5 is provided in a position lower than the processing pan 4, and an exhaust port 11 is provided in a position higher than the upper end of the ion exchange resin 3 to flow the gases upward.
