| 中文摘要: |
| 以Pb(NO3)2为模拟污染物,研究了电动力技术对铅污染红壤修复的适应性.结果表明大部分铅能在阴极附近富集.土壤的pH值是影响电动力土壤修复的主要因素,pH值可以通过降低土壤的电导率而导致槽电压升高和土壤发热;还可以通过改变铅的存在形态而降低其修复效率.电动力技术需经过改进才能用于铅污染红壤的修复. |
| 英文摘要: |
| Ex-situ electroremediation tests are conducted on the lead-spiked actual red soils spiked with Pb(NO_3)_2.The tests show that the electroremediation technology is efficient to remedy Pb contaminated red soils;pH value of red soil is the major factor of dominating electroremedition: pH value of red soil can not only lead to high tank voltage and high temperature of red soil by means of decreasing electro-conductivity of soil,but also reduce remediation efficiency by precipitating Pb and then decreasing mobility of Pb.Hence,electroremediation techniques should be enhanced so as to apply to remedy Pb contaminated red soils. |
