The system comprises a leachate collection and drainage layer, a first HDPE (high-density polyethylene) geomembrane impervious layer, a clay layer and a groundwater collection and drainage layer which are sequentially stacked from top to bottom. The clay layer is composed of a lower clay layer, a middle clay layer and an upper clay layer which are sequentially arranged, wherein the middle clay layer is filled with a medium-fine sand layer laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water contents ‰¤ 3%, wherein the saturated permeability coefficient of the medium-fine sand layer varies from 1×10 -5 to 1×10 -3 cm/s. Therefore, breakdown time of the leachate can be greatly prolonged, and the imperious effects of a refuse landfill impervious layer can be enhanced; meanwhile, the medium-fine sands are readily available as they are low in cost and widely spread in China. The refuse landfill impervious system capable of prolonging breakdown time of the leachate has a simple structure and is able to effectively prevent the groundwater from permeating in order to saturate the medium-fine sand layer, keeping the medium-fine sand layer in an unsaturated state all the time.
