中文摘要：

垃圾在长期填埋所产生的“中老龄”垃圾渗滤液是目前公认的难降解废水,针对这类废水可生化性差、低C/N、氨氮含量高等特点,主要从物化法、生化法和短程生物脱氮3个方面介绍国内外该类渗滤液的处理技术,并分析各种处理技术的特点,最后指出未来该类渗滤液处理的主要研究方向.

英文摘要：

The stabilized landfill leachate,which is produced from the long-term landfill process,is widely recognized as the most refractory wastewater.In view of its poor biochemistry,low C/N,high ammonia nitrogen content,etc,from the physical-chemical method,biological method and short biological denitrification.This paper mainly introduces the treating technology for waste leachate at home and abroad,and analyzes the characteristics of various processing methods,and finally,points out the main research direction of the leachate treatment in the future.
