Effects of Completely Symmetrical Electric Field on Electro-Bioremediation of Oil Contaminated Soil

  • 摘要: 针对石油这种非极性复杂有机污染物难以去除的特点,以含油量为50 mg/g的石油污染土壤为研究对象,运用行/列循环切换方式,每5 min切换一次电极极性,建立空间和场强上完全对称的电场,旨在研究完全对称电场条件下电动-微生物联合修复对石油污染物去除率的影响. 对土壤有效氮、有效磷、有效钾等营养物含量以及降解菌数量在电场作用下的变化进行比较. 结果表明,1 V/cm的电压梯度下,土壤中的w(有效氮),w(有效磷)和w(有效钾)分别为初始值的1.3,1.6和1.2倍;同时,在电场作用和电极极性切换条件下,土壤的pH为6.3±0.2,温度升高2~3 ℃,石油降解菌的数量增加,当处理时间为20 d时,降解菌数量最大值达2.3×109  CFU/mL,进而提高了石油的去除率. 烷烃在电动处理下降解速率加快,60 d烷烃去除率达到15.73%. 经过60 d的电动-微生物修复,石油去除率达到33.42%,是对照组的2.4倍.
