PROBLEM TO BE SOLVED: To treat, on an occasion for treating a pollutant within a life space with a treatment agent, the pollutant so as to ultimately minimize the treatment agent remaining within the life space.SOLUTION: A pollutant treatment apparatus 10 includes: a reclaimer 1 for recovering a pollutant W treatment agent feeding means 2 for feeding, into an outer sphere of the reclaimer 1 or into the reclaimer 1, a treatment agent for treating the pollutant W existing within a life space R air stream formation means 3 for forming, in a state where the treatment agent is being fed by the treatment agent feeding means 2, an air stream targeting the life space R and destined toward the reclaimer 1 and for transporting, into the reclaimer 1, the pollutant W within the life space R being carried by the air stream so as to enable the recovery thereof within the reclaimer 1 in a state where the stream is accompanied by the fed treatment agent and pollutant W and discarding means 4 for discarding, out of the reclaimer 1, the pollutant W to which the treatment agent reclaimed within the reclaimer 1 after having been carried by the air stream formed by the air stream formation means 3 is adhered. An air cleanliness maintenance system using the pollutant treatment apparatus 10 and an air circulator 11 is also targeted.COPYRIGHT: (C)2014,JPO&INPIT【課題】生活空間の汚染物質を処理剤で処理するに当たり、生活空間に余剰な処理剤を極力残さないように汚染物質を処理する。【解決手段】汚染物質処理装置10として、汚染物質Wを回収する回収器1と、回収器1外又は回収器1内に生活空間Rに存在する汚染物質Wを処理するための処理剤が供給される処理剤供給手段2と、処理剤供給手段2にて処理剤が供給された状態で生活空間Rに対し回収器1に向かう気流を形成し、供給された処理剤と汚染物質Wとが付着した状態で回収器1に回収されるように気流に乗せて生活空間Rの汚染物質Wを回収器1に搬送する気流形成手段3と、気流形成手段3により形成された気流に乗って回収器1に回収された処理剤が付着した汚染物質Wを回収器1外に廃棄する廃棄手段4と、を備える。汚染物質処理装置10と空気循環装置11とを用いた空気清浄維持システムをも対象とする。【選択図】図1
