我々を取り巻く環境問題のーつとして，工場・病院の排気臭や，飲食店・惣菜店のちゆう房排気臭などの悪臭問題がある。対策として，既存脱臭技術（洗浄法，吸着法，燃焼法，オゾン脱臭法，プラズマ脱臭法，光触媒脱臭法，生物脱臭法，消・脱臭剤法，希釈・拡散法）を利用するが，原理・特徴を十分に理解して装置選定をしなければ期待する効果を得ることは難しい。本稿では，脱臭設備計画に必要な脱臭技術の原理・特徴を解説する。%As one of the environmental problems surrounding us, there is an offensive odor problem including exhaust gas odor from factories, hospitals, as well as kitchen exhaust odor from restaurants and food shops. As countermeasures, the following deodorization technologies have already been established : scrubbing method, adsorption method, combustion method, ozone deodorization method, plasma deodorization method, pho-tocatalyst deodorization method, biological deodorization method, deodorant method, and dilution / dispersion method. However, without the prudent selection of equipment after sufficient understanding of its principles and features, expected effects can hardly be obtained. This paper discusses the principles and features of deodorization technologies required for planning deodorizing equipment.
