| 摘 要： | 以焦化废水原水为研究对象,采用Fenton氧化法进行预处理,在考察H2O2用量与反应时间对焦化废水中CODCr,、挥发酚去除率影响的基础上,重点分析反应体系中有毒难降解有机物浓度的变化.通过GC-MS分析发现,在反应温度为30℃、H2O2用量为1/2理论量、n(Fe2 ):n(H2O2)=1:20的条件下,酚、苯系物、石油烃、含氮杂环有机物和多环芳烃在反应10min时相应的去除率分别达到93.7%、96.2%、92.1%、92.7%和89.2%,此时挥发酚类物质去除率为98.6%,COD去除率为54.4%.结果表明,焦化废水经Fenton氧化预处理不仅能取得较高的CODCr、挥发酚类物质去除率,而且能将其中有毒难降解有机污染物氧化为较易生物降解的醇、醛、酮及有机酸等中间产物,有利于后续生物处理过程.
