摘要：

A 2D-laboratory box experiment (12 x 56 x 116 cm) was conducted to simulate the enhancement of soil vapor extraction by the application of low frequency electrical heating (joule heating) for the remediation of a low permeable, silty soil contaminated with trichloroethylene. Joule heating enlarged the flux of extracted TCE with a factor 19 (when boiling) in comparison to the removal rates achieved by soil vapor extraction alone (at 23 degrees C). Within 45 days a removal of 99.8% of the TCE was accomplished.
