Fenton试剂对垃圾渗滤液中有机物的去除特性研究

Study on Removal Characteristics of Organic Matter in Landfill Leachate by Fenton Reagent

采用Fenton试剂处理垃圾渗滤液,在最佳试验条件下,考察了Fenton试剂对渗滤液中不同表观分子质量和不同种类有机物的去除效果。结果表明,Fenton试剂对表观分子质量>2ku的COD和表观分子质量>4ku的UV254的去除效果较好,去除率分别大于60%和80%。Fenton试剂对富里酸(FA)的去除率为85%,对腐殖酸(HA)的去除率为68.4%,对亲水性有机物(HyI)的去除率为36.5%。

Landfill leachate was treated by Fenton reagent, and the removal effect of the different organic matters with different apparent molecular weights （AMW） in the landfill leachate by Fenton reagent was investigated under the optimal conditions. The results show that COD with AMW above 2 ku and UV254 with AMW above 4 ku can be removed effectively by the Fenton reagent, and the removal rates are higher than 60% and 80% respectively. After treated by Fenton reagent, the removal rates of fulvic acid （FA） , humic acid （HA） and hydrophilic organic matters are 85% , 68.4% and 36.5% respectively.
