摘　　要：采用多种先进测试分析仪器对不同月份的垃圾填埋场渗滤液生物处理尾水（简称渗滤液尾水）进行了全面的分析。结果表明，经生物处理后的渗滤液尾水难以进一步生物降解，仍然有很强的污染性，COD和NH3-N仍分别高达419～622、12．4～174．0mg／L，未达到国家排放标准，且仍含有多种环境优先控制污染物。除有机物外，渗滤液尾水中还有部分无机类物质贡献COD，TN主要由无机氮构成。渗滤液生物处理的效果与温度关系密切，6、9月的处理效果明显好于3、12月。Comprehensive chemical analysis was performed on biologically treated sanitary landfill leachate samples taken in March, June, September and December. The biologically treated leachate was still highly polluted with mostly persistent organic compounds, including some priority pollutants. COD and NH3-N of the biotreated leachate were 419-622 mg/L and 12.4-174.0 mg/L, respectively, both exceeding the corresponding national discharge limits. Those samples also contained some inorganic compounds that would contribute to COD. TN of the biotreated leachate was mostly inorganic nitrogen. Effectiveness of the biological leachate treatment was dependent on temperature; the samples taken in June and September were far better treated than those taken in March and December.
