摘　　要：生活垃圾填埋场随着时间的推移,其渗滤液水质也会发生较大的变化,老龄化填埋场渗滤液氨氮浓度大幅升高,而有机污染物浓度大幅下降,C/N值严重失调,MBR等传统硝化反硝化生化处理工艺不适宜处理老龄填埋场渗滤液。采用氨吹脱、厌氧氨氧化和"JS-BC"处理工艺可以有效去除氨氮,节省能耗、降低运行成本,对整个行业节能减排、渗滤液处理达标排放具有重要意义。The quality of landfill leachate changes dramatically with the lapse of time. There would be a dramatic rise in ammonia nitrogen concentration, a sharp fall in organic pollutants and a seri- ous imbalance in C/N ratio of leachate from aged domestic landfill. Traditional nitrification and denitrifi- cation processes such as MBR are no longer suitable for aged landfill leachate treatment. Ammonia strip- ping, Anammox and ＂JS-BC＂ treatment process could effectively remove ammonia nitrogen, save energy and reduce the operation cost, which is of great importance in energy-saving, emission reduction and up- to-standard discharge of treated leaehate for the whole industry.
