摘要

报告了采用膜生物反应器（MBR）—纳滤（NF）组合工艺处理高浓度垃圾渗滤液，该工艺充分发挥了MBR和NF单元的功能互补性，运行实践表明，对COD和氨氮的平均去除率均达99.5 %，出水满足《生活垃圾填埋污染控制标准》的一级标准，运行费用（含折旧）为19.55元/m³，具有较明显的技术经济优势。

Abstract

Landfill leachate is a serious pollution with high COD and NH₃-N. The MBR-NF process was adopted to treat the leachate. The results showed that the average removal efficiency of COD and NH₃-N both reached 99.5 %, and the purified water could reach the first level of standard for pollution control on the landfill site for domestic waste. The total operation cost was 19.55 yuan/m³. Compared with the other leachate treatment processes, the MBR-NF has significant advantages on both technique and economic sides.
