摘　　要：研究了微电解和上流式厌氧污泥床(UASB)组合工艺处理城市垃圾渗滤液的效果。结果表明:微电解是一种理想的垃圾渗滤液预处理方法,其CODCr去除率可达到56.3%,B/C由原水的0.28上升到0.35;UASB能够有效地处理微电解处理后的出水,CODCr去除率能达73%以上。微电解和UASB组合工艺能去除城市垃圾渗滤液中的大部分CODCr,并提高其可生化性。The treatment of landfill leachate by microelectrolysis-UASB has been studied.The results show that microelectrolysis is a good and cheap pretreatment process,56.3% of CODCr could be removed from landfill leachate,and B/C is improved from raw water 0.28 to 0.35.UASB could treat the effluent effectively after treated by microelectrolysis process,the CODCr removal rate is more than 73%.The combined microelectrolysis-UASB process could remove most of the CODCr from landfill leachate and improve its biodegradability.
