Lining of solid waste landfill
The invention discloses a lining of a solid waste landfill which is composed of loess, HDTMA and bentonite. The lining is prepared from the components in percentage by mass: greater than or equal to 50% and less than or equal to 86.2% of the loess, greater than or equal to 50% and greater than or equal to 12.1% of the bentonite, greater than or equal to 0.5% and less than or equal to 1.7% of the HDTMA, and greater than or equal to 20% of the loess of 0.005 mm. The plastic limit index of the loess is less than or equal to 10, and the plastic index of the bentonite is greater than or equal to 30. The lining of the solid waste landfill does not generate cracks or is not prone to generating cracks, the permeability coefficient meets the requirement, and the adsorption effect on organic matter can be improved.
一种固体废物填埋场的衬里，由黄土，HDTMA和膨润土组成，按照质量分数计，50%≦黄土含量≦86.2%，50%≥膨润土≥12.1%，0.5%≦HDTMA≦1.7%；另外粒径<0.005 mm的黄土≥20%，黄土的塑限指数≦10，膨润土的塑性指数≥30。本申请提供的固体废物填埋场的衬里不产生或者不易产生裂隙，渗透系数满足要求，可以提高对有机物的吸附效果。
