Embodiment Construction

[0042] The invention proposes an anti-seepage material—waterproof and air-permeable particles, and according to its characteristics, it is combined with permeable bricks to form an anti-seepage system for landfill plants.

[0043] The landfill anti-seepage system, landfill structure and landfill method of the present invention will be described below in conjunction with the accompanying drawings.

[0044] figure 1 It is a schematic diagram of a preferred embodiment of the anti-seepage system of the present application, such as figure 1 As shown, the anti-seepage system, which is applied in the landfill plant, includes: an anti-seepage layer 6, which is a waterproof and breathable particle layer, and a liquid and gas diversion layer 5, placed in the anti-seepage top of layer 6.

[0045] figure 2 It is a schematic diagram of another preferred embodiment of the anti-seepage system of the present application, such as figure 2 shown, with figure 1 The difference of the illus...

Abstract

The invention discloses an anti-seepage system and a landfill structure. The anti-seepage system is applied to landfills, and comprises an anti-seepage layer, a liquid and gas flow guide layer and a pre-drained liquid filtering layer, wherein the anti-seepage layer is a waterproof breathable granular layer; the liquid and gas flow guide layer is arranged above the anti-seepage layer; and the pre-drained liquid filtering layer is arranged above the liquid and gas flow guide layer and is a permeable brick layer. The landfill structure comprises an underground soil layer, the anti-seepage system, a waste layer and an earth surface soil layer, wherein the anti-seepage system is laid on the underground soil layer; the waste layer is positioned on the anti-seepage system; and the earth surface soil layer is embedded above the waste layer. Water-proof breathable sand is used as a main anti-seepage material, the water-proof breathable sand has water-proof breathable function, solves the problems that waste produces toxic gas and prevents soil and underground water from being polluted by percolate; and the anti-seepage material is a flexible material, does not produce cracks under the action of shearing force of the stratum and can effectively keep the anti-seepage effect.

Description

technical field [0001] The invention relates to the field of landfill technology, in particular to an anti-seepage system for landfill, a landfill structure and a landfill method. Background technique [0002] With the rapid development of urbanization, a large amount of garbage is produced. Among the future crises predicted by the world's authoritative scientists, the garbage problem is one of them. A large amount of garbage damages the ecology and pollutes the environment, seriously affecting human life. For waste disposal, the main method of waste disposal in most countries including China is sanitary landfill, but most landfills are relatively simple, the performance of anti-seepage system is not good, and there is no professional landfill air conduction system , the leachate produced by the garbage has caused serious pollution to the soil and water bodies, and the free discharge of landfill gas has caused safety hazards to the landfill site, and at the same time cause...
