摘　　要：本研究在实验室恒温恒湿的条件下,将无重金属污染的土壤配制成不同浓度铜污染的待试土壤,研究加入不同修复材料(沸石、凹凸棒石、蒙脱石)对污染土壤的影响,明确不同修复材料对污染土壤的修复效果。结果表明:3种修复材料平均修复率表现为沸石>凹凸棒石>蒙脱石;整体上,3种修复材料对铜污染土壤均有一定的修复效果,沸石和凹凸棒石修复效果相近,均比蒙脱石修复效果好;在不同总铜含量土壤中,3种修复材料的修复效果存在差异,沸石的修复效果优于蒙脱石和凹凸棒石。This study prepared soil without heavy metal pollution into test soil with different concentrations of copper pollution under constant temperature and humidity conditions in the laboratory.The effects of adding different remediation materials(zeolite,attapulgite,montmorillonite)on polluted soil were studied,and the remediation effects of different remediation materials on polluted soil were clarified.The results showed that the average remediation rate of the three remediation materials was zeolite>attapulgite>montmorillonite;overall,all three remediation materials had a certain remediation effect on copper contaminated soil,zeolite and attapulgite had similar remediation effects,both were better than montmorillonite;there were differences in the remediation effects of the three remediation materials in soils with different total copper contents,and zeolite had a better remediation effect than montmorillonite and attapulgite.
