The progress relating to landfill leachate end treatment,landfill leachate resourceful treatment technology including organic fertilizer production,recovery of ammonia nitrogen and humic acid,anaerobic methane fermentation,bio-hydrogen was reviewed.Due to high gasification efficiency,fast reaction speed and high hydrogen concentration in gaseous product,supercritical water gasification was used to achieve hydrogen from biomass.Idea of treatment of landfill leachate using supercritical water gasification was put forward in this paper.Landfill leachate could be treated effectively.At the same time hydrogen produced in gaseous product was recovered.The combination of leachate treatment and resource recovery was realized.%回顾了垃圾渗滤液(简称渗滤液)末端处理,利用渗滤液生产有机肥料、燃料,回收渗滤液中氨氮和腐殖酸,厌氧发酵制沼气,生物制氢气等渗滤液资源化利用技术的研究进展;提出了超临界水气化(SCWG)技术具有气化效率高、反应速度快、气体产物中氢含量高等特点,被广泛应用于生物质制氢的研究;指出了利用SCWG技术处理渗滤液不仅能对渗滤液进行有效治理,并且能回收反应产生的氢气资源,实现渗滤液污染治理和资源回收的有机结合.
