PROBLEM TO BE SOLVED: To provide a liquid treatment apparatus capable of irradiating water to be treated with all of the ultraviolet light emitted from an ultraviolet lamp neither too much nor too little, in order to sufficiently treat water with ultraviolet light even if the kind or quantity of water is varied.SOLUTION: The liquid treatment apparatus includes a water-passing drum through the inner part of which liquid to be treated flows, and to which outer piping through which the liquid to be treated flows is connected so as to configure a flow path of the liquid to be treated. An ultraviolet-irradiating unit has an ultraviolet lamp for irradiating the liquid to be treated with ultraviolet light and is provided in the water-passing drum, and a rectification member is provided in a flow path between the outer piping and the ultraviolet-irradiating unit to rectify the liquid to be treated flowing in the vicinity of the ultraviolet lamp. |
