To provide a sterilization/deodorization system capable of economically and efficiently carrying out sterilization/deodorization of the chamber spaces, walls and ceilings without unnecessarily enhancing the humidity in a chamber even if the system is used in facilities having a wide chamber space such as welfare facilities, hospitals, preschools, kindergartens, schools or the like.SOLUTION: An objective sterilization/deodorization system is characterized by: using a supersonic spray device which is equipped with a water storage tank comprising a duct having a hollow-cylindrical shape, detachably installed to the above spray device and guiding the fine particles of an aqueous solution of hypochlorite generated by the spray device, and generates dry mists along the central axis of a hollow cylinder； and detaching the water storage tank from the spray device, charging the hypochlorite tablet and water in the storage tank to prepare an aqueous hypochlorite solution, and then mounting the water storage tank filled with the aqueous hypochlorite solution to the spray device.SELECTED DRAWING: Figure 3【課題】本発明は、室内の湿度を不必要に上げることなく、福祉施設、病院、保育園・幼稚園・学校などの広い室内空間を有する施設で使用しても、室内空間および壁、天井の除菌・消臭を経済的・効率的に行うことができる除菌・消臭システムを提供する。【解決手段】中空円筒の形状であり、超音波式噴霧装置に着脱自在に取り付けられ、中空円筒の中心軸に沿って、前記超音波式噴霧装置で発生させた次亜塩素酸水溶液の微粒子を導く管路を備える、形状・構造を有する貯水槽を備えた、ドライミストを発生する超音波式噴霧装置を用いること、および、貯水槽を超音波式噴霧装置から脱着し、貯水槽内に次亜塩素酸タブレットおよび水を投入して次亜塩素酸水溶液とした後に、この次亜塩素酸水溶液が充填された貯水槽を超音波式噴霧装置に装着することにより、解決することができる。【選択図】図３
