| 摘 要： | 通过室内模拟培养试验,研究不同投加比例的硫酸亚铁和腐熟猪粪对铬污染土壤的改良效果研究。结果表明,浸出毒性Cr(Ⅵ)约27.0～30.5 mg/L的铬污染土壤,添加4%的FeSO_4·7H_2O修复后,浸出毒性降至约0.04 mg/L,土壤肥力情况恶化,土壤较贫瘠;修复后土壤添加1.4%的腐熟猪粪培肥,土壤有机质含量较空白对照组提高了71.99%,碱解氮、有效磷与速效钾含量分别是对照的1.33、2.72和16.23倍,土壤综合肥力较肥沃,利于后期农业生产。结果表明,施用硫酸亚铁和腐熟猪粪不仅能有效降低铬污染土壤毒性浸出浓度,达到较好的土壤修复效果,而且显著提高土壤肥力,实现土壤生态改良。
