Landfill leachate guiding and discharging system
The invention discloses a landfill leachate guiding and discharging system, and relates to the technical field of landfill leachate guiding and discharging. The system comprises a partition dam arranged in a landfill and used for dividing the landfill into a plurality of landfill areas, a main guiding and discharging ditch, secondary guiding and discharging ditches, multiple main guiding and discharging pipes, secondary guiding and discharging pipes, a collection well and a pumping and discharging pipe. The main guiding and discharging ditch is arranged at the bottom of a landfill and penetrates through the landfill areas and the partition dam, and one end of the main guiding and discharging ditch is higher than the other end; the secondary guiding and discharging ditches are formed at thetwo sides of the main guiding and discharging ditch and arranged at a slope toe of a side slope of the landfill, and one end of each secondary guiding and discharging ditch is higher than the other end; the plurality of main guiding and discharging pipes are arranged at the bottom of the main guiding and discharging ditch; the secondary guiding and discharging pipes are arranged at the bottoms ofthe secondary guiding and discharging ditches; the collection well is arranged at the slope toe of the side slope at the end, close to the main guiding and discharging ditch, of the landfill, and iscommunicated with the other ends of the main guiding and discharging pipe and the secondary guiding and discharging pipes; one end of the pumping and discharging pipe is arranged in the collection well; and the guiding and discharging system can achieve partitioned guiding and discharging of landfill leachate, the guiding and discharging pressure of all the guiding and discharging pipes is reduced, the guiding and discharging system is provided with the secondary guiding and discharging pipes, and effective guiding and discharging of the leachate can be further ensured.
本发明公开了一种填埋场渗沥液导排系统，设计填埋场渗沥液导排技术领域，包括：分区坝，设置于填埋场内部，将填埋场分隔成多个填埋区；主导排沟，设置于填埋场的底部，贯穿填埋区和分区坝，主导排沟的一端高于另一端；次导排沟，设置于主导排沟的两侧，设置于填埋场的边坡的坡脚处，次导排沟的一端高于另一端；多根主导排管，设置于主导排沟的底部；次导排管，设置于次导排沟的底部；收集井，设置在填埋场靠近主导排沟的一端的边坡的坡脚处，与主导排管和次导排管的另一端相连通；抽排管，一端设置于收集井内；该导排系统能够实现填埋场渗沥液的分区导排，降低各导排管的导排压力，并且具有次导排管，能够进一步确保渗沥液的有效导排。
