垃圾渗滤液资源化技术研究进展

Research Progress in the Resource Utilization of Landfill Leachate

圾渗滤液中许多污染物也是可回收利用的资源,对其进行资源化利用不仅可以获得一定的经济效益,也有利于渗滤液处理成本的降低。因此,本文介绍了垃圾渗滤液在回收化学物质、与固废联合处理、微生物燃料电池产电、制取氢气、培养能源微藻五个资源化方向的研究进展,分析了各种技术的优点与不足,并对其应用前景进行了展望。

Many pollutants in landfill leachate are also available resources. If we could recycle resources from landfill leachate, certain of economic benefits would be achieved and the treatment cost of landfill leachate would be reduced. Therefore, this paper introduced the latest research progress in the utilization technology of landfill leachate in the aspects of recovery of chemicals, combined treatment with solid waste, electricity generation by microbial fuel cell, hydrogen production and energy microalgae cultivation. And the advantages, disadvantages and prospects of those technologies were analyzed.
