Embodiment 1
[0053] The contaminated soil repaired in this example is the petroleum-contaminated soil configured in the laboratory. The soil collected is clay to remove visible impurities and grass roots. The room is naturally air-dried and passed through a 2mm sieve. The petroleum is collected from a certain company in Shuguang Oil Production Plant of Liaohe Oilfield. The oil pit is prepared into 40g / kg±10g / kg oil-contaminated soil, left in natural air for 7 days, adjusted to 25% moisture content with deionized water, and loaded into an electric remediation tank (length 100cm×width 100cm×height 15cm).
[0054] In this embodiment, the electric field dynamic control method based on soil electrical parameters, the specific implementation steps are ( figure 1 ): 1) Measure the concentration field of pollutants in organic contaminated soil, determine the location and polarity of the electrode; 2) Calculate the input voltage according to the pollutant concentration classification and soil electrica...
