PHOTOCATALYTIC WATER TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To dissolve and peel inorganic scale attached to a storage tank storing water to be treated, pipes and jackets of ultraviolet lamps without using any chemical. SOLUTION: This photocatalytic water treatment apparatus decomposes organic and inorganic substances in water 100 to be treated using the storage tank 11, and is provided with an apparatus body part 2 disposed outside the storage tank 11; a circulating line consisting of a water taking-in pipe 8 connected to a water taking-in side of the body 2 and a discharge pipe 9 connected to a discharge side of the body 2; a pump 4 circulating the water 100 to be treated; a filter 5 provided in the body 2; a photocatalytic treatment means provided on a downstream side of the filter 5 using photocatalyst carriers 7 and the ultraviolet lamps 6; and an electrode part 3 provided in the tank 11. The water 100 to be treated is electrolyzed by energizing the electrode part 3. COPYRIGHT: (C)2005,JPO&NCIPI
