摘要
以 30 0W高压汞灯为光源 ,研究了紫外光联合臭氧化、单纯臭氧氧化及单纯紫外光照处理 4 0 0mg/L的活性艳红K 2BP废水的可行性。结果表明 :光催化臭氧化可加速有机物的矿化。在同样时间条件下 ,三者氧化能力由大至小为 :UV/O3 >单独O3 >单独UV。运用TOC、紫外 可见光谱 (UV Vis)、毛细管电泳 (CE)等分析技术初步探讨了紫外光催化臭氧化活性艳红K 2BP溶液的降解效果及降解机理。
The oxidation of of 400 mg/L reactive red K-2BP wastewater were studied by photocatalytic ozonation, ozonation and ultravioletlight irradiation respectively. 300 W high-pressure mercury lamp was used as the light source. Results showed that the removal of TOC was great enhanced by photocatalytic ozonation. At the same condition, the oxidation abilities of three systems were: UV/O 3>O 3 >UV. The mechanism of degradation was explored primarily by TOC removal, UV-Vis spectrometer and capillary electrophoresis(CE) analysis.
