ULTRAVIOLET WATER TREATMENT DEVICE

摘要

The ultraviolet water treatment device of an embodiment is provided with an ultraviolet ray irradiation tank, an inlet tube for supplying the water to be treated, and an outlet tube for discharging the treated water. The ultraviolet ray irradiation tank is provided with multiple ultraviolet ray irradiation modules. The multiple ultraviolet ray irradiation modules comprise multiple ultraviolet ray-irradiating tubes, a cleaning device and a cleaning device drive unit. The multiple ultraviolet ray-irradiating tubes comprise multiple ultraviolet lamps and multiple ultraviolet lamp-protecting tubes that protect each ultraviolet lamp individually. The cleaning device cleans the surface of each ultraviolet lamp-protecting tube. The cleaning device drive unit drives the cleaning device. Each ultraviolet ray module comprises two ultraviolet ray-irradiating tubes or three ultraviolet ray-irradiating tubes.
