摘要/Abstract

摘要： 研究了不同催化臭氧体系（O3、UV/O3和Fe2+/UV/O3）对腈纶废水的降解特性，Fe2+/UV催化臭氧表现出极强的COD降解性能。详细分析了pH值、Fe2+浓度、气相臭氧浓度和光强各因素对Fe2+/UV催化臭氧降解性能的影响规律。结果表明，溶液初始pH值对其降解性能无影响，而Fe2+浓度、气相臭氧浓度和光强影响较大。当Fe2+的优化浓度为70～80mg/L，气相臭氧浓度为20～30 mg/L和光量子流密度为8.62×10-12Einstein时，催化效果最强，COD去除率最高（72%～78%）。经红外光谱测试分析，废水中有机物基团经Fe2+/UV催化臭氧降解后减弱或消失，其生物降解性得到改善。

Abstract: The oxidation degradation of acrylic fibers wastewater was studied with different catalysis ozonation systems (O3，UV/O3 and Fe2+/UV/O3). The Fe2+/UV catalysis ozonation system showed strong oxidation capacity. The influence on oxidation capacity was discussed，such as pH，Fe2+ concentration，gas phase ozone concentration and light intensity. The result showed that the initial solution pH had no effect on oxidation capacity，but other factors had significant effect. With optimal Fe2+ concentration 70～80mg/L，gas phase ozone concentration 20~30mg/L，photon flux density 8.62×10-12 Einstein，catalysis performance was the best，and COD removal rate was the highest (70%~80% COD removal). According to infrared spectrometry analysis，organic components became weak or disappeared by the Fe2+/UV catalysis ozonation system，and biological degradability of acrylic fiber wastewater was improved greatly.
