摘要： A fluid sterilization device includes: a straight tube that defines a processing flow passage; a light source that radiates ultraviolet light toward the processing flow passage in an axial direction of the straight tube; and a light receiving part that receives a portion of the ultraviolet light output from the light source. The straight tube is made of a fluororesin. The straight tube includes a recess formed in a part of an outer wall surface of the straight tube such that a thin part is partly provided in the straight tube. The thin part has a radial thickness from an inner wall surface of the straight tube that is smaller than a thickness in other parts. The light receiving part is provided in the recess to receive the ultraviolet light transmitted through the thin part.

摘要： A sterilization apparatus is provided with: a light source, which has a semiconductor light-emitting element that emits ultraviolet light; a housing, which forms a flow passage through which a fluid subject to sterilization passes; a light receiving unit, which receives a portion of the ultraviolet light emitted from the light source and detects the amount of ultraviolet light that has been received; and a control unit, which controls the output of the semiconductor light-emitting element based on information regarding the amount of ultraviolet light acquired from the light receiving unit. The housing has an incidence portion on which ultraviolet light becomes incident and a reflection portion, which reflects the ultraviolet light at the inner surface thereof. The light receiving unit is provided at a position where the light receiving unit can receive the portion of ultraviolet light that has been transmitted through the reflection portion.

摘要： A water treatment device includes: a dual-pipe structure unit including an outer pipe, an inner pipe provided in the outer pipe, and a prevention member provided between the outer pipe and the inner pipe; and a light source unit radiating ultraviolet light in the axial direction to irradiate water subject to treatment flowing in the inner pipe. The inner pipe includes an opposing end facing the light source unit across a gap and an inflow end positioned opposite to the opposing end. The outer pipe includes an outflow port provided on an outer circumferential surface of the outer pipe. The water subject to treatment flowing out of the inner pipe via the gap flows out from the outflow port.
