Heavy metal contaminated soil and mine slope combined remediation method
The invention discloses a heavy metal contaminated soil and mine slope combined remediation method which comprises the following steps that a waste mine slope is arranged into a slope comprising a plurality of horizontal steps, an impermeable film is paved on the mine slope, an anchoring groove is arranged, retaining walls are arranged around a mine, a drainage ditch and a reservoir are arranged at the slope angle of the mine, a heavy metal contaminated soil layer for herbaceous plants to grow is laid on the impermeable film, the herbaceous plants for enriching heavy metals are planted on the heavy metal contaminated soil, and the water quality in the reservoir is regularly detected and treated, so that under the dual action of rainwater leaching and gravity, part of heavy metal in the soil is migrated to the horizontal steps to be absorbed by the plants, the problem of soil pollution is solved on the basis that special equipment and a large number of chemical agents are not needed and the properties of the soil are not damaged, meanwhile, the problem of water and soil loss of the mine is solved, and remarkable environmental and economic benefits are achieved.
本发明公开了一种重金属污染土壤和矿山坡面联合修复方法，通过以下步骤：对废弃的矿山坡面整理成包含若干水平阶梯的坡面，在所述矿山坡面上铺设防渗膜，设有锚固沟槽，在所述矿山四周设置挡土墙，位于所述矿山坡角处设有排水沟、蓄水池，在所述防渗膜上铺设用于草本类植物生长的重金属污染土壤层，在所述重金属污染土壤上种植富集重金属的所述草本类植物，定期对所述蓄水池内的水质定期检测、处理；使雨水淋溶和重力双重作用下，土壤中部分重金属迁移到水平阶梯被植物吸收，在不需特殊的设备和大量的化学药剂，不破坏土壤的性质的基础上解决了土壤污染问题，同时解决了矿山的水土流失问题，具有显著的环境、经济效益。
