摘要:
采用单一电动力修复技术和电动力耦合活性炭可渗透反应格栅(EK-PRB)技术,对铬(Ⅵ)污染农田土壤进行修复实验.结果表明:电动力耦合活性炭(PRB)技术能有效地修复铬(Ⅵ)污染土壤;在同等能量利用率的情况下,污染土壤铬(Ⅵ)的去除率比单一电动力技术提高5.87%,为99.45%,能量利用率为7.38 %·(kW·h)-1,土壤pH值变化幅度不大;EK-PRB技术能充分利用2种技术的优点,提高铬(Ⅵ)去除率,对土壤pH值影响较小,不易造成土壤酸化现象.
Abstract:
Electrokinetic remediation coupled with activated carbon permeable reactive barrier(EK-PRB)was taken to remediate Cr(Ⅵ)contaminated farmland soil. The results showed that electrokinetic remediation coupled with activated carbon permeable reactive barrier(PRB)promoted the remediation efficiency of Cr(Ⅵ)contaminated soil. The total removal of Cr(Ⅵ)increased to 99.45%, 5.87% higher than the conventional electrokinetic method at the same energy utilization ratio. Its energy utilization efficiency was 7.38 %·(kW·h)-1, and the rangeability of soil pH value was small. Therefore, EK-PRB can take the full advantages of the two technologies to improve the removal efficiency of Cr(Ⅵ)and have less effect on soil pH value, which is not easy to make the soil acidified.
