摘要
矿山的开发利用不可避免地会对周边的生态环境造成污染,其中重金属污染问题更是越发受到公众关注,对废弃或者退役的矿山周边受污染土壤开展修复治理技术研究显得十分迫切。本次实验通过筛选各种稳定剂针对重金属Cd和Zn污染土壤进行修复效果研究,稳定剂沸石处理后的土壤中Zn的残渣态含量占比则稍高于其他三种稳定剂;泥炭对于Cd的可交换态去除效果显著优于其他三种稳定剂,能够有效减少污染土壤中Cd的可交换态含量,降低其迁移率。
The development and utilization of mines will inevitably cause pollution to the surrounding ecological environment,among which heavy metal pollution has attracted more and more public attention.It is urgent to carry out research on the remediation and treatment technology of contaminated soil around abandoned or decommissioned mines.In this experiment,various stabilizers were screened to study the remediation effect of heavy metal Cd and Zn contaminated soil.The residual content of Zn in the soil treated with stabilizer zeolite was slightly higher than that of the other three stabilizers.The exchangeable state removal effect of peat on Cd is significantly better than the other three stabilizers,which can effectively reduce the exchangeable state content of Cd in polluted soil and reduce its mobility.
