| 摘 要： | 垃圾渗滤液是一种复杂有毒的、生化降解性差的高浓度有机废水,高级氧化技术具有氧化能力强和无二次污染等特点,被认为是处理难降解有机污染物最有应用前景的方法.本研究在500 W汞灯、25℃、2.5 h反应条件下,对比了TiO_2、K2S2O_8、K2S2O_8/Fe2+、施氏矿物、施氏矿物/H2O_2、Fe2+/H2O_26种催化剂组合光化学处理垃圾渗滤液的效果.结果表明,施氏矿物/H2O_2和Fe2+/H2O_2光催化降解垃圾渗滤液中有机污染物的效果优于其它催化剂组合,渗滤液中CO_D去除率分别为41.6%和46.5%,TO_C去除率分别为76.0%和78.1%.然而,Fe2+/H2O_2组合在光催化处理垃圾渗滤液后会产生大量难以沉降的Fe(O_H)3絮状物,且渗滤液色度明显增加,由初始的40倍上升到175倍.而施氏矿物/H2O_2组合则避免了上述问题,色度去除率达100%,被认为是一种具有应用前景的光化学降解垃圾渗滤液的催化剂组合.
