An object of the present invention is to dissolve and peel scales of inorganic substances adhering to a storage tank for storing water to be treated, piping, and a jacket of an ultraviolet lamp without using any chemicals. A photocatalytic water treatment apparatus for decomposing organic substances and inorganic substances in water to be treated 100 using a storage tank 11, an apparatus main body 2 disposed outside the storage tank 11, A circulation path composed of a water intake pipe 8 connected to the water intake side of the apparatus main body 2 and a discharge pipe 9 connected to the discharge side of the apparatus main body 2, a pump 4 for circulating the treated water 100, A filter 5 provided in the apparatus main body 2, a photocatalyst treatment means using a photocatalyst carrier 7 and an ultraviolet lamp 6 provided on the downstream side of the filter 5, and an electrode part 3 provided in the storage tank 11. When the electrode unit 3 is energized, the water 100 to be treated is electrolyzed. [Selection] Figure 1 |
