To provide an air deodorization sterilization method for deodorizing and sterilizing air to be treated, an air deodorization sterilization device and an air deodorization sterilization system.SOLUTION: An air deodorization sterilization method includes: a step of suspending air to be treated in water to be treated containing free hypochlorite； and a step of radiating UV-ray to the water to be treated in which the air to be treated is suspended. An air deodorization sterilization device or an air deodorization sterilization system 50 includes: a treatment tank 30 filled with the water to be treated containing free hypochlorite； an inlet 1 for intaking the air to be treated into the treatment tank 30； a bubble generator 3 that suspends the air to be treated in the water to be treated in the treatment tank 30； and a UV-light source 7 for radiating UV-ray to the water to be treated in which the air to be treated is suspended.SELECTED DRAWING: Figure 2【課題】 被処理空気を除臭および殺菌する空気除臭殺菌方法、空気除臭殺菌装置および空気除臭殺菌システムを提供すること。【解決手段】 本空気除臭殺菌方法は、遊離次亜塩素酸を含有する処理水に被処理空気を懸濁する工程と、被処理空気が懸濁された処理水に対し、近紫外線を照射する工程とを含む。本空気除臭殺菌装置または空気除臭殺菌システム５０は、遊離次亜塩素酸を含有する処理水が満たされる処理槽３０と、被処理空気を処理槽３０内に取り入れる取入口１と、処理槽３０内の処理水に被処理空気を懸濁させる気泡発生器３と、被処理空気が懸濁された処理水に対し近紫外線を照射する紫外線光源７とを含む。【選択図】 図２
