| 摘 要： | 对甘肃某垃圾填埋场渗滤液的来源、进水水质和设计出水水质进行分析,从可生化性、系统运行稳定性、渗滤液高浓度、高毒性等方面考虑,最终确定采用MBR＋两级DTRO系统对渗滤液进行处理.经该工艺处理后,COD、BOD5、NH3-N、TN和SS的去除率分别为：99.3％、99.6％、98.7％、98.4％和97.0％,出水水质能够满足《生活垃圾填埋场污染控制标准》（GB 16889-2008）标准要求.该系统优点：抗冲击能力强、污泥浓度低、占地面积小、出水水质稳定.

| Abstract: | This study adopts MBR and two-stage DTRO system processes to analyze the landfill leachate by source,water quality,biodegradability,stability of system running,high concentration and high toxicity of landfill leachate.The average removal rates of CODcr,BOD5,NH3-N,TN and SS is 99.3％,99.6％,98.7％,98.4％ and 97.0％,after the process of crafts.The water quality can meet the standards of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste （GB 16889-2008）.The system has many advantages,such as strong ability to resist assault,low sludge concentration,small footprint,and stable water quality. |
