Built-in leachate collection and discharge modular pump station device for refuse landfill
The invention belongs to the technical field of sanitary landfill of refuse, and discloses a built-in leachate collection and discharge modular pump station device for a refuse landfill. The device adopts a sectional modular design and mainly comprises a water collection section, a water inlet section, a well barrel section and a wellhead section, wherein a water pump fixed mounting platform and a mud pit are arranged at the bottom of the water collecting section; the water inlet holes are evenly distributed in the side wall of the water inlet section, so that a pump station water inlet pipe does not need to be additionally arranged, leachate is collected through the leachate guiding and discharging layer and then enters the water collecting section through the water inlet section, and the design of the landfill leachate collecting, guiding and discharging pump station is simplified. The well barrel section is designed in a segmented mode, and therefore the height of the well barrel can be gradually increased according to the landfill condition so as to adapt to rising of a landfill pile body. The arrangement position of the pump station is changed into a built-in type from a traditional external type, so that the percolate guiding and discharging pipe is prevented from penetrating through a side slope impermeable layer of the landfill, the percolation risk in the percolate collecting, guiding and discharging process is reduced, and meanwhile, the purposes of optimizing the design of a guiding and discharging system and reducing the construction cost can be achieved.
本发明属于垃圾卫生填埋技术领域，公开了一种垃圾填埋场内置式渗滤液收集与排出模块化泵站装置，它采用分段式模块化设计，主要包含集水段、进水段、井桶段、井口段；集水段底部设水泵固定安装平台和沉泥坑；进水段侧壁设置有均匀分布的进水孔，因此无需另外设置泵站进水管，渗滤液经渗滤液导排层汇集后将通过进水段进入集水段，简化了填埋场渗滤液收集导排泵站设计；井桶段采用分段设计，因此能够根据垃圾填埋情况逐步增加井桶高度，以适应填埋堆体的升高。本发明将泵站设置位置由传统外置式更改为内置式，从而避免渗滤液导排管穿越填埋场边坡防渗层，降低渗滤液收集导排过程中的渗滤风险，同时也能达到优化导排系统的设计、降低工程造价的目的。
