摘　　要：垃圾渗滤液反渗透浓缩液含盐、高浓度有机物和营养物质。该文开展单室空气阴极式的微生物燃料电池(Microbial Fuel Cell,MFC)处理广西某垃圾填埋场不同盐度的垃圾渗滤液反渗透浓缩液的处理研究。结果表明,盐度越低,处理效果越好,当以低盐度浓缩液混合乙酸钠作为处理对象时,效果最佳,浓缩液中COD、NH_(3)-N和TN的去除率分别达到90.91%、46.54%、64.89%。MFC处理垃圾渗滤液反渗透浓缩液为高效低能耗处理提供新途径。The reverse osmosis concentrate of garbage leachate contains salts,high concentrations of organic matter,and nutrients.A single-chamber air-cathode microbial fuel cell(MFC)treatment of landfill leachate with different salinity in a landfill site in Guangxi was carried out.The results show that the lower the salinity,the better the treatment effect.When low-salinity concentrate mixed with sodium acetate is used as the treatment object,the effect is the best,and the removal rates of COD,NH_(3)-N and TN in the concentrate reach 90.91%,46.54%,and 64.89%,respectively.MFC treatment of landfill leachate reverse osmosis concentrate provides a new approach for efficient and low energy consumption treatment.
