DRAINAGE TREATMENT DEVICE AND DRAINAGE TREATMENT METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a drainage treatment device capable of effectively decomposing an organic substance present in drainage water with low energy and to provide a drainage treatment method using the same.;SOLUTION: An ultraviolet oxidation device includes: a flowing tank 12 for causing treatment water to flow in one direction; a photocatalyst fiber 14 arranged in the flowing tank 12 so that the treatment water can pass therethrough; an ultraviolet irradiation part 16 capable of irradiating ultraviolet rays; and an ultraviolet irradiation part-storage part 18 which is provided in the fluid tank 12, and stores the ultraviolet irradiation part 16 so as to irradiate the ultraviolet rays to the photocatalyst fiber 14. In the drainage treatment device, the ultraviolet irradiation part-storage part 18 is constituted so that the treatment water can flow in the ultraviolet irradiation part-storage part 18. The treatment water is constituted to be introduced into the fluid tank 12 after flowing in the ultraviolet irradiation part-storage part 18.;COPYRIGHT: (C)2013,JPO&INPIT
