| 摘 要： | 笔者以生态友好材料核桃壳和花生壳为修复材料，以铅污染的土壤为供试土壤，采用人工模拟土壤污染的方法，通过投加不同比例的修复材料，用土壤重金属的有效态比率变化作为评价指标，对修复效果做出科学评价，以期为农林废弃物在铅污染土壤治理中的应用提供科学依据。试验结果表明：（1）核桃壳和花生壳对轻度Pb污染土壤的修复效果比较理想，在模拟的污染水平下，Pb的有效态下降范围为17.59%~19.22%；（2）对于同一污染水平，投加核桃壳和花生壳比例不同，修复效果不同，在给定的投加范围内，核桃壳和花生壳的最佳投加比例为5%；（3）核桃壳和花生壳对于严重铅污染土壤的修复效果不理想；（4）花生壳对铅的修复效果要好于核桃壳。

| Abstract: | In order to study repairing methods for soil contaminated by Pb,eco-friendly material walnut shell and peanut hull were used to remedy soil contaminated by Pb.By artificial methods of soil pollution and adding different proportions of repairing material,the ratio changes of active state of heavy metals were evaluated and a scientific assessment was made to provide a scientific basis for restoration of soil contaminated by Pb.The results showed that:(1)walnut shell and peanut hull were applicable to the ligh... |
