PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation apparatus in which the exchangeability of an electrodeless lamp is improved and a microwave is emitted efficiently toward the electrodeless lamp to improve the properties of a fluid. SOLUTION: A lamp house 11, in which the electrodeless lamp 13 is integrated with a magnetron 12 for supplying microwave energy, and a housing part 17 for housing the water to be treated are constituted in separated spaces. Ultraviolet rays can be made to pass through the lamp house 11 and the housing part 17 through a screen 18 arranged in an irradiation window 112 and a photocatalytic substance-deposited cleaning member 19 can be irradiated with ultraviolet rays in the water which is to be treated and is housed in the housing part 17. As a result, the lamp house 11 can be removed from the housing part 17 and the electrodeless lamp 13 housed in the lamp house 11 can be exchanged easily. Therefore, the maintenance of the electrodeless lamp 13 can be facilitated and the running cost of the ultraviolet irradiation apparatus can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
