摘　　要：开发了一种处理垃圾渗滤液的新型催化剂。将纳米Fe3O4@MOF作为催化剂应用于垃圾渗滤液的电芬顿处理,考察了Fe_(3)O_(4)@MOF投加量、渗滤液初始p H、H_(2)O_(2)投加量等因素对COD去除效果的影响。结果表明,当Fe_(3)O_(4)@MOF投加量为0.75 g/L,反应120 min后,COD的去除率达到70.8%,色度的去除率达到了94.25%。GC-MS和三维荧光结果显示,渗滤液中大分子有机物及富里酸和腐殖酸类物质得到了很好的降解转化,可生化性得到了提升。说明Fe3O4@MOF是一种高效的电芬顿催化剂。A new catalyst for treating landfill leachate has been developed.Nano-Fe_(3)O_(4)@MOF was applied as a catalyst to the electro-Fenton treatment of landfill leachate.The effects of nano-Fe_(3)O_(4)@MOF dosage,initial leachate pH and H_(2)O_(2) dosage on COD removal efficiency were investigated.The results showed that when the Fe3 O4@MOF dosage was 0.75 g/L,the removal rate of COD reached 70.8%and the removal rate of chroma reached 94.25%after 120 min reaction.The results of GC-MS and 3 D-EEM showed that the macromolecular organic matter,humic acid and fulvic acid in the leachate were well degraded and transformed,and the biodegradability was improved.It showed that the Fe3 O4@MOF was a highly efficient electroFenton catalyst.
