| 摘 要： | 文章以垃圾渗滤液为研究对象,分别用铁粉、改性膨润土、活性炭及其混合物为反应介质,设计4种不同介质配比的PRB反应器进行实验研究。结果表明,PRB对垃圾渗滤液有较好的处理效果,其中,以还原铁粉、改性膨润土为介质的反应器,对氨氮的去除效率最大为97.58%,以还原铁粉、活性炭为介质的反应器对COD的去除效率为84.87%,对总磷的去除效率最大为80%。

| Abstract: | Three reaction media(zero valent iron,activated carbon and modified bentonite) were used to design four kinds of permeable reactive barriers(PRB) to study the feasibility and the efficiency of the PRB technology in the remediation of landfill leachate.The result indicated PRB had great removal effect of landfill leachate.The ammonium removal rates in the two reaction medias with zero valent iron and modified bentonite was 97.58% at the maximum,the removal rate of COD in reactors with zero valent iron and activated carbon was 84.87% at the maximum,the removal rate of total phosphorus in PRB reactors was 80% at the maximum. |
