【摘要】 运用锯齿膜超滤加两级卷式膜纳滤分离系统处理垃圾渗沥液,系统出水无色透明,COD总去除率99%以上,氨氮总去除率90%以上,达到国家一级排放标准.结果表明:膜法处理垃圾渗沥液的技术是切实可行的.更多还原

【Abstract】 Ultrafiltration and two-step nanofiltration were adopted to treat the municipal landfill leachate.The permeate was colorless and clear,its rejection of COD was more than 99%,its rejection of N-NH₃ was more than 90%.The permeate reached the first-grade national discharge standard.So this experiment shows that the treatment of municipal landfill leachate with membrane separation technology is very practical and promising.更多还原
