垃圾填埋场渗沥液回灌及沼气收集利用

Artificial Recharge of Leachate and Collection Utilization of Methane in Landfill Yard

垃圾渗沥液和填埋气是垃圾填埋过程中的两种主要产物,具有很强的二次污染性。该文结合工程实例,阐述了渗沥液回灌与沼气收集利用发电相结合,不但可以实现渗沥液减量化,降低渗沥液处理成本,同时可以促进垃圾分解沼气的产生,并进行沼气收集利用发电。

The garbage leachate and the landfill gas are the main products in the course of garbage landfill,which are very strong secondary pollution. According to the engineering case,the article sets forth that the combination of artificial leachate recharge with methane collection utilization can not only realize the leachate decrement,reduce the leachate treatment cost,but also can promote the production of garbage breaking down methane and carry out the methane collection and utilization for generating electric power.
