PROBLEM TO BE SOLVED: To provide a liquid treatment device realizing further improvement of treating capacities such as sterilization and organic material decomposition despite its cost-reduced, compact and simple configuration.SOLUTION: A fine bubble generator and ultraviolet lamp are arranged in a treating container having a flow path through which a liquid to be treated is passed, and the generation of fine bubbles and ultraviolet irradiation are nearly simultaneously performed without leaving large time interval in the identical container. By a combined effect of the above treatment, further improvement of treating capacities such as sterilization and organic matter decomposition is achieved. In other words, by irradiating the liquid to be treated just after supply of fine bubbles with ultraviolet light, oxygen or the like in the fine bubbles is activated to further improve efficiencies of sterilization and decomposition. Besides, by irradiating the liquid just after the fine bubbles are broken by applying pressure with the ultraviolet light, in addition to the active OH group generated by ultraviolet irradiation, the active groups generated in response to pressure break of fine bubbles join to the OH group and thus, the efficiencies of sterilization and decomposition are further improved by accelerated treatment.COPYRIGHT: (C)2012,JPO&INPIT【課題】 小型であってコストダウンを図った簡素な構成でありながら殺菌並びに有機物分解といった処理能力のさらなる向上を実現した液体処理装置の提供。【解決手段】 被処理液体が通される流路を有する1つの処理容器内に微細気泡発生手段と紫外線ランプとを配置してなり、同一の処理容器内で微細気泡の発生と紫外線照射とを時間間隔をあまり空けずにほぼ同時に行うことによって、これらによる複合効果により被処理液体の殺菌並びに有機物分解といった処理能力のさらなる向上を実現した。微細気泡が供給された直後の被処理液体に対して紫外線を照射すると、微細気泡中の酸素等が活性化されて殺菌並びに分解効率がより向上する。微細気泡が圧壊した直後の被処理液体に対して紫外線を照射すると、紫外線照射に応じて生成される活性OH基に加えてさらに微細気泡の圧壊に応じて生成される活性基が加わり、処理が加速されて殺菌並びに分解効率がより向上する。【選択図】 図1
