摘　　要：采用UV-A波段中发光波长为376 nm的固体紫外光源技术,设计出大面积UV-LED(ultraviolet light emit-ting diode)纳米光催化有机废水深度处理装置.结果表明:UV-LED/TiO2光催化装置对次甲基蓝有着优良的降解效率,能够为该装置工业化的应用提供科学依据.In this paper,development of ultraviolet light emitting diode（UV-LED）/TiO2 device and their application for photocatalytic degradation of methylene blue were reported.The UV-LED with an output wavelength of 376 nm in UV-A band was applied as the UV light source for the photocatalytic decomposition of methylene blue.The decomposition of methylene blue in aqueous solution by TiO2 photocatalytic processes with the UV-LED was found to be technically and actually feasible,showing a promising technique for organic waste water treatment by the UV-LED/TiO2 method.
