PERFORMANCE CHECK METHOD OF UV RAY IRRADIATION DEVICE, REFERENCE UV RAY IRRADIATION DEVICE, UV RAY IRRADIATION DEVICE SYSTEM, AND REFERENCE UV RAY IRRADIATION DEVICE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a performance check method of a UV ray irradiation device that can check a UV ray irradiation performance of the UV ray irradiation device after introduced to a premise, facility, and the like.;SOLUTION: According to an embodiment, a performance check method of a UV ray irradiation device 1 is provided. The method includes the steps of: causing a reference UV ray irradiation device 5 to conduct UV ray irradiation with respect to treatment water W₁ containing a substance decomposable or chemically changeable due to an ultraviolet ray, and calculating a reaction rate coefficient of the substance specific to the treatment water by using obtained substance concentration prior to and after the UV ray irradiation; and causing the UV ray irradiation device 1 to conduct UV ray irradiation with respect to the treatment water W₁ containing the substance decomposable or chemically changeable due to an ultraviolet ray, and calculating volume average luminance of the UV ray irradiation device 1 by using the obtained substance concentration prior to and after UV ray irradiation and the reaction rate coefficient.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
