Municipal solid waste landfill barrier system capable of prolonging breakthrough time of leachate and manufacturing method thereof
The invention relates to a MSW (municipal solid waste) landfill barrier system capable of prolonging breakthrough time of leachate and a manufacturing method thereof. The system comprises a leachate collection and removal layer, a first HDPE (high-density polyethylene) geomembrane infiltration proof layer (2), a clay liner (5) and a groundwater collection and removal layer (6) which are sequentially stacked from top to bottom. The clay liner (5) is composed of a lower clay liner (51), a middle clay liner (52) and an upper clay liner (53) which are sequentially arranged, wherein the middle clay liner (52) is filled with a medium-fine sand layer (7) laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water content ≤3%, wherein the saturated hydraulic conductivity of the medium-fine sand layer (7) varies from 1×10−5 to 1×10−3. A method of manufacturing the MSW landfill barrier system capable of prolonging breakthrough time of leachate is also provided.
