Rigid landfill waste gas collection-percolate guide and discharge integrated device and rigid landfill waste gas collection-percolate guide and discharge integrated method
The invention discloses a waste gas collection-leachate guide and discharge integrated device and method for a rigid landfill, and belongs to the technical field of hazardous waste disposal. The device comprises a fixed waste gas collecting, guiding and discharging structure and a movable leachate lifting structure, the upper end of a waste gas collecting pipe is a three-way T-shaped pipe, the lower end of the waste gas collecting pipe extends to the bottom of a rigid landfill reservoir area, a side pipe is communicated with the waste gas collecting pipe close to a landfill cell and then is conveyed to a waste gas treatment system through a fan, and the upper end of the waste gas collecting pipe is an openable closed cover plate. When it is detected that much leachate exists in the rigid landfill cells, a side pipe valve is closed, a top sealing cover plate is opened, a leachate guide and discharge pipe is lowered to the bottoms of the landfill cells through a waste gas collecting pipe, and a lifting pump is started to discharge the leachate. Holes are prevented from being formed in the bottoms of the rigid landfill cells, and leachate can be lifted while waste gas is collected.
本发明公开了一种刚性填埋场废气收集‑渗滤液导排一体化装置及方法，属于危险废物处置技术领域。该装置包括固定式废气收集导排结构和移动式渗滤液提升结构，废气收集管的上端为三通T型管，下端延伸至刚性填埋场库区底部，侧管与临近填埋单元格废气收集管连通后由风机送至废气处理系统，上端为可开启式密闭盖板，当检测到刚性填埋单元格内渗滤液较多时，关闭侧管阀门，开启顶部密闭盖板，将渗滤液导排管通过废气收集管下放至填埋单元格底部，启动提升泵将渗滤液排出。本发明避免了在刚性填埋单元格底部开孔，在收集废气的同时能实现渗滤液提升。
