  • 摘要: 为得到土壤气相抽提(SVE)去除柴油的优化条件，进行了一维土柱抽气提取去除柴油污染物的实验研究，研究不同初始含水率、不同抽气量对污染土壤中柴油去除率的影响及不同深度残留柴油的变化规律。结果表明：在本实验模拟的范围内，抽气量越大，SVE处理效果越好；初始含水率越低，处理效果越好；此外，不同深度去除率变化的规律基本上是随深度的增大而减小。实验结果可为土壤轻油污染实际治理提供实验数据基础。
    Abstract: An experimental study on quantifying the optimum condition of diesel removal by soil vapor extraction (SVE) technology was conducted and implemented through tests of a onedimensional column filled with dieselcontaminated soil. This experiment was mainly focused on the effects on the diesel removal rate caused by different extraction vapor flow rates and different initial soil moisture contents and variation trends of residual diesel with depth in testing columns. The results show that under the condition of the experimental simulation, better recovery is achieved with a higher extraction flow rate; when the initial soil water content goes down, the removal efficiency goes up. In addition, the results show that the removal efficiency of diesel declined with the increasing of soil depth. These results offer the basic experimental data for removal of LNAPL in soil remediation which is useful in engineering practice.
