老龄垃圾渗滤液处理技术研究进展

摘要

垃圾在长期填埋过程中产生的老龄垃圾渗滤液成分复杂,处理更为困难.老龄垃圾渗滤液具有氨氮含量高、C/N低、可生化性差等特点.从物化处理、生化处理和生物脱氮等方面对国内外该类渗滤液的处理工艺进行了分析,指出了各种处理方法的优势与不足,并在此基础上对老龄垃圾渗滤液处理技术的发展进行了展望.%The aged landfill leachate produced from the long-term landfill process has complicated components,and,moreover,is difficult to be treated.It is characterized by high ammonia-nitrogen content,low C/N,poor biodegradability,etc.The treating technologies for treating aged landfill leachate in China and abroad are analyzed in the aspects of physical-chemical treatment,biochemical treatment and biological denitrification,etc.And the advantages and disadvantages of various treatment methods are pointed out,and based on this,the development of aged landfill leachate treatment technologies are looked ahead.
