【摘要】 采用湿式催化氧化法对垃圾渗滤液进行处理,制备了活性炭载铜、铁系列催化剂,以O₃/H₂O₂为氧化剂, COD去除率为考察指标,考察了反应工艺条件对垃圾渗滤液的处理效果。结果表明:在焙烧温度为600℃,Cu、 Fe物质的量比为3∶1时,制得的Cu-Fe/AC复合催化剂的催化剂活性相对较好;当水样体积为20 m L, H₂O₂投加量为0.5 mL, O₃通入时间为25 min（O3流量为5 g/h）,催化剂投加量为1 g时, pH值在2～4和10～12时的COD去除率较好。更多还原

【Abstract】 Wet catalytic oxidation was used to teat landfill leachate, series catalysts of copper and iron carrying activated carbon were prepared. With H₂ O₂/O₃ as oxidant, removal rate of COD as investigation indicator,the effect of reaction condition on landfill leachate treatment was studied. The results showed that, Cu-Fe/AC composite catalyst prepared under the condition that calcinations temperature was 600 ℃, mass ratio of Cu to Fe was 3 ∶ 1, had relatively good activity. When the water sample quantity was 20 mL, the H₂O₂ dosage was 0.5 mL, the O₃ aeration time was 25 min（flow of O₃ was 5 g/h）, the catalyst dosage was 1 g, the pH value was 2-4 or 10-12, good removal efficiency of COD could be obtained.更多还原
