| 摘 要： | 研究了Fenton氧化对某实际有机氯农药污染场地土壤的修复效果。结果显示:Fenton氧化能够快速有效地降解污染土壤中的六氯和DDTs。当Fe2+浓度为80 mmol/L,Fe2+与H2O2的摩尔浓度比为1∶5,水土比10∶1时,反应6 h,土壤中六氯和总DDT的去除率分别为:96.7%和78.2%。每方土的修复成本估算为951元。

| Abstract: | The remediation of organochlorine pesticides contaminated soil using Fenton oxidation was studied.The results showed that the organochlorine pesticides were efficiently degraded by Fenton reagent.Under the condition that the initial concentration of ferrous iron was 80mmol/L,the molar concentration ratio of ferrous iron and hydrogen peroxide was 1∶5 and the liquid-to-soil ratio was 10∶1,the removal rate of hexachloride and ∑DDT in contaminated soil were 96.7% and 78.2% respectively after 6 h reaction.The remediation cost of per stere of contaminated soil was about 951 yuan. |
