摘　　要：为探究氧化—淋洗协同修复有机和重金属复合污染土壤的效果,对3种不同复合污染类型的土壤采用湿法氧化协同淋洗的工艺进行修复,实验结果显示,氧化处理导致重金属的去除率降低,但可以大幅度提高有机物的去除率。氧化—淋洗协同处理法对不同种类有机和重金属复合污染土壤均有较好的处理效果。与常规氧化修复方式相比,湿式氧化工艺能够促进污染物与药剂的充分接触和反应,有利于协同高效去除不同种类的污染物。In order to explore the effect of oxidation-leaching synergistic remediation of soil contaminated by organic and heavy metal complexes,a wet oxidation synergistic leaching process was used on soils of three different types of complex pollution.The results showed that oxidation treatment led to a reduction in the removal rate of heavy metals,but it could greatly improve the removal rate of organic matter.The oxidation-leaching collaborative treatment method has good treatment effects on different types of organic and heavy metal composite contaminated soils.Compared with conventional oxidation repair methods,the wet oxidation process can promote the full contact and reaction between pollutants and chemicals,which is conducive to the coordinated and efficient removal of different types of pollutants.
