Nano-clay modified loess liner suitable for household garbage landfill
The invention discloses a nano-clay modified and compacted loess liner suitable for a household garbage landfill. The raw materials of the nano-clay modified and compacted loess liner comprise nano-clay and loess. A preparation and maintenance method comprises the following steps that 3-14% of nano-clay is doped into the loess by using a dry mass blending method, and is uniformly mixed, the water content of a mixture is kept at 15%-17%, the mixture is covered with a plastic film, and is placed in a dry and shade place, a soil sample is sequentially turned over after two days to ensure that a modified material makes full contact with the loess and water of the loess, and the modified loess is compacted to the maximum dry density after curing for 5 days. The nano-clay modified and compacted loess liner is remarkable in anti-seepage effect, can meet the requirements for the stability and the anti-seepage performance of the garbage landfill, adjusts measures to local conditions, saves the cost of manual anti-seepage materials greatly, and has very important practical significance on comprehensive utilization of loess according to local conditions, reasonable design of the anti-seepage liners of landfills and pollution prevention and control of soil, surface water and underground water.
本发明公开了一种适用于生活垃圾填埋场的纳米粘土改性压实黄土衬垫，原料包括纳米粘土和黄土，制备和养护的方法为，利用干质量掺配法将3％～14％的纳米粘土掺入黄土中，混合均匀，并使其含水量保持在15‑17％，盖上塑料薄膜后置于干燥阴凉处，两日后依次翻动土样，保证改性材料与黄土及其水分充分接触，养护5日后将改性黄土压实到最大干密度。本发明防渗透效果显著，能够满足垃圾填埋场的稳定性和防渗性能的要求，实现因地制宜，大大节省人工防渗材料的费用，对黄土因地制宜的综合利用、填埋场防渗衬垫的合理设计及土壤、地表水和地下水的污染防治具有非常重要的现实意义。
