摘    要:对铅污染的原状土壤在不同修复时间下的修复效果和采用极性交换技术的修复效果进行了试验,分析了试验过程中电流、电导率、pH的变化以及试验完成后土样中含水率、电导率、pH值和铅的分布,并对每个试验中铅的去除率进行了计算.结果表明:随着修复时间的增加污染物的去除率相应提高,采用极性交换技术,去除率明显提高.并对动电技术发展进行了展望,提出了建议.

关 键 词:动电修复    原状土  极性交换  去除率

Abstract:Electrokinetic remedied Pb-polluted undisturbed soil was studied in four experiments,which are under different remediation time and with polarity-reversal technology.The variation of the electrical current,pH and the electrical conductivity during the process of remediation as well as the water content,the electrical conductivity and the distribution of Pb2+ in soils after the remediation were analyzed.The removal efficiency of Pb2+ of all experiments was calculated.The results indicate that increasing the ...
Keywords:electrokinetic remediation  Pb2+  undisturbed soil  polarity-reversal  removal efficiency
