摘要:研究了不同催化臭氧体系(O2、UVO3和Fe2UvO2)对腈纶废水的降解特性,FeUV催化臭氧表现出极强
的COD降解性能。详细分析了pH值、Fe(浓度、气相臭氧浓度和光强各因素对Fe几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Fe浓度、气相臭氣浓度和光强影彩响较大。当Fe?'的优化浓度为70
80mg兀L,气相臭氧浓度为20~30mgL和光量子流密度为8.62x10" Einstein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 syst ems( UV/O and Fe V/). The Fe U catalysis zonation system showed strong
oxidation capacity, The influence on oxidation capacity was discussed, such as PH, Fe""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 Fe " concentration 70
80mg/L, gas phase zone concentration 20-30mg/L, photon flux density 8.62x10"Einstein, catalysis
performance was the best, and COD removal rate was the highest(70%-80% COD removal).According to
ozonation system, and biological degradability of acrylic fiber wastewater was improved great Catalysis
infrared spectrometry analysis, organic components became weak or disappeared by the Fe/UV catalysis
