Abstract:
Disclosed is an ultraviolet oxidation device for decompositing organic materials present in water in low energy consumption and low cost, an ultrapure water production device using the same, an ultraviolet oxidation method, and an ultrapure water production method. An ultraviolet oxidation device including: a flow tank 10; photocatalyst fibers 12; an ultraviolet radiating unit 14; and an ultraviolet radiating unit housing unit 16 which is arranged to occupy an entire cross-section of the flow tank intersecting with flowing direction of the water to be processed in the flow tank 10; wherein the ultraviolet radiating unit housing unit 16 is constructed such that the water to be processed flows toward the ultraviolet radiating unit 14 from an upstream side, and after flowing in the housing unit 16, the water to be processed flows out to a downstream side, and is formed of a material that allows the ultraviolet rays from the ultraviolet radiating unit 14 to radiate the photocatalyst fibers 12.
Abstract:
A fluid treatment apparatus particularly for sterilizing drinks comprises an elongate tubular duct (110) and an elongate UV light source (111) extending longitudinally of the duct (110). The fluid flows longitudinally of the duct (110) in a thin annular low passage (114) which extends around the UV light source (111). A mixing device (112) disposed between adjacent longitudinal portions of the duct (110) for diverts all of the fluid flowing along a first portion of the passage (114) through fluid mixing means (113,116) in the device (112) and returns the mixed fluid to a second portion of the passage (114). Micro-organisms in the thin flow of fluid are killed as they come within close proximity of the light source (111). The mixing device (112) causes all of the flow to be thoroughly mixed and returned to the flow passage (114). The provision of a plurality of mixing devices along the length of the duct (110) increases the likelihood that all microorganisms receive a sufficient lethal dose of UV radiation.
