PROBLEM TO BE SOLVED: To provide a method and apparatus for decomposing organic matter, which, by effectively using active species generated by discharge plasma and having a relatively long life, make the active species react efficiently with organic matter containing a harmful hard-to-decompose material and enable unconventionally fast decomposition of an odorant than conventional methods and which is also effective for disinfection of airborne bacteria.SOLUTION: The organic matter is decomposed by introducing a gas in which the organic matter is present and a mixed gas containing at least nitrogen or a nitrogen compound as discharge gases in a plasma region generated by atmospheric glow discharge.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】放電プラズマにより生成した比較的長寿命の活性種を有効活用することで、効率よく有害な難分解性物質の有機質と反応させ、従来にない高速な臭気物質の分解を可能とし、さらに、浮遊菌の殺菌にも効果がある有機質の分解方法及び装置を提供すること。【解決手段】大気圧グロー放電により発生させたプラズマ領域内に、有機質が存在するガスと、少なくとも窒素又は窒素化合物を含む混合ガスとを放電ガスとして導入し、前記有機質を分解することを特徴とする。【選択図】図2
