Abstract:

The amount of landfill leachate from domestic waste in Henan Province，China，is 80 m³/d. The landfill leachate is characterized by high COD，poor biodegradability and high NH₃-N content. The combined treatment process，striping－UASB－A/O－MBR－RO，has been designed for treating landfill leachate. The main design parameters of every process unit are introduced． The debugging and operation results show that all of the indexes of the effluent water are superior to the limit value requirements of pollutant discharging concentration in Standard GB 16889-2008.

Key words: landfill leachate, upflow anaerobic sludge bed, membrane bio-reactor, reverse osmosis

摘要：

河南省某市生活垃圾填埋场的渗滤液产生量为80 m³/d，该渗滤液具有COD高、可生化性差、NH₃-N含量高等特点．设计采用吹脱—UASB—A/O—MBR—反渗透组合工艺进行处理，介绍了各工艺单元的主要设计参数．调试运行结果表明，出水各项指标均优于GB 16889—2008中的污染物排放浓度限值要求．
