摘要
随着国家对环境污染治理的重视力度不断加强,对土壤重金属污染的治理与修复也越来越重视。实验研究了5组钝化剂对土壤中重金属稳定效率的影响,分析探讨影响重金属稳定效率的原因。实验结果表明土壤p H值会对重金属稳定性造成直接影响,在5组钝化剂中,石灰对重金属的稳定起主导作用,腐殖质+石灰复配组合对土壤重金属治理与修复比较可行。
With country＇s continuous strengthened emphasis on environmental pollution control efforts, management and restoration of soil heavy metal pollution is becoming more and more attention. This paper made experimental research on the influence of five groups passivator on stability efficiency of heavy metals in soil, analyzed and discussed the influence reasons of the stability efficiency of heavy metals. The experimental results showed that the soil pH value will directly influence on stability of heavy metals, lime play a leading role in the stability of the heavy metals in the five groups of passivator, humic ＋ lime complex formula combination is feasible for heavy metals management and restoration in soil.
