Domestic waste landfill closure covering system
The invention relates to the technical field of household garbage landfill closure, in particular to a household garbage landfill closure covering system. The invention provides a closure covering system for a household garbage landfill, which is characterized in that structural layers of the closure covering system sequentially comprise a greening soil layer, a drainage layer, an impermeable layer, a water vapor collecting layer and an exhaust layer from top to bottom; transverse or vertical pipelines are evenly arranged in a domestic garbage heap, and a water storage tank and a water pump are arranged to form a water circulation system. A pipeline in the water circulation system is connected with a water pump; the water pump is connected with a water storage tank; capillary waterproof and drainage plates with omega-shaped grooves and collecting grooves are adopted in the water vapor collecting layer, the capillary waterproof and drainage plates are arranged in the extending direction of the omega-shaped grooves in a segmented mode, and the capillary waterproof and drainage plates at the segmented positions are in lap joint in the collecting grooves. The water vapor collecting layer in the closure covering system is used for collecting water vapor, so that the leachate in the garbage heap is reduced, a pretreatment effect on the leachate is achieved, and the cost is saved.
本发明涉及生活垃圾填埋场封场技术领域，具体为一种生活垃圾填埋场封场覆盖系统。本发明提供一种生活垃圾填埋场封场覆盖系统，其特征在于：封场覆盖系统结构层由上至下，依次为绿化土层、排水层、防渗层、水蒸气收集层、排气层；在生活垃圾堆体中均匀布置横向或竖向管道，并配置储水罐及水泵组成水循环系统；所述水循环系统中的管道与水泵连接，水泵与储水罐连接；所述水蒸气收集层采用带有“Ω”槽的毛细防排水板及收集槽，所述毛细防排水板沿“Ω”槽延伸方向分段布置，分段处毛细防排水板搭接于收集槽内。本发明利用封场覆盖系统中水蒸气收集层收集水蒸气，使的垃圾堆体内的渗滤液得到减量化，对渗滤液起到预处理作用，节省费用。
