摘　　要：以紫外发光二极管(UV-LEDs,365 nm)为光源,进行光电芬顿处理次甲基蓝废水.研究了紫外光、电流、铁离子投量、鼓气量等条件对UV-LEDs光电芬顿降解染料次甲基蓝的影响。结果表明:LED.紫外光显著促进了次甲基蓝降解,在10mg·L^-1Fe^2+、电流30mA、鼓氧量200 mL·min^-1的条件下,初始质量浓度为50 mg·L^-1的次甲基蓝矿化率达52%.The methylene blue wastewater was treated by photoelectro-Fenton process with UV-LEDs(ultraviolet light emitting diodes,365 nm).The influences of the UV light,the currents,the amount of iron ions and the bubbling oxygen on the degradation of methylene blue have been studied.The results indicate that the degradation of methylene blue was obviously enhanced by the UV-LED light.When the concentration of Fe^2+was 10 mg·L^-1,the current was 30 mA,and the oxygen bub-bling rate was 200 mL·min^-1,the mineralization ratio of 50 mg·L^-1methylene blue was 52%.
