摘　　要：利用模拟垃圾填埋装置进行渗滤液回灌处理的研究,取回灌处理后期的渗滤液与未经回灌处理渗滤液进行水质监测,并运用GC-MS联用技术对两种水样的有机成分进行对比分析。结果表明,羧酸类物质在检出物中所占比例较大,回灌处理对渗滤液中羧酸类物质的去除率达到61.26%,接近于CODC r的去除率59.65%。对一些毒害性物质也有一定的去除,哌啶类物质去除率为79.52%,呋喃的去除率为100%。The recirculation treatment of landfill leachate with the simulated landfill leachate treatment was studied and the water quality of the latter part of leachate recireulation and without dealing with leachate recirculation was monitored, and the organic components of two kinds of water samples was ana- lyzed by using GC-MS method. The results showed that acid substances have a large proportion in the de- tection of objects. The removal rate of acid substances of the leachate recirculation treatment is up to 61.26%, and is close to the removal rate of CODc~. Some toxic substances can be removed at a eertain degree. The removal rate of piperidine material is 79.52% ,removal rate of furan is 100%.
