填埋场填埋气体收集竖井提升方法探讨

Analysis and Discussion on the Extending of the Vertical Wells in the Landfill

处于服务期内的填埋场采用竖井进行填埋气体收集时,气体收集受填埋作业影响较大。为了最快地恢复作业区域填埋气体收集、最大限度地延长填埋气体收集竖井的使用寿命,降低收集系统的建设成本,需要对该区域的气井进行提升。文章对收集竖井提升方法、效率及经济性等方面进行了综合比较与总结,为收集竖井提升工作提供借鉴和参考。

The landfill gas collection is greatly affected by the filling operation in such sites which deploy vertical well to collect landfill gas.The vertical wells which drilled in filling area need to be extended so as to recover the landfill gas collection as soon as possible,extend the service of the vertical wells and reduce the costs for construction of the collection system.The paper compared and summarized various methods on extending of the vertical wells aimed to provide lessons to upgrading of the vertical wells in the landfill sites which were still in service.
