Method of in-situ cleaning by means of microorganisms of a polluted soil portion

摘要

A method is described for the in-situ cleaning by means of microorganisms of a polluted soil portion which contains ground water. In this method, the soil portion to be cleaned is enclosed, and one or several electrodes which are permeable to liquid are placed in or adjacent the soil portion. A negative or positive voltage is applied to these electrodes. The enclosure of the polluted soil portion takes place in such a manner that the ground water present in the soil portion flows mainly through the one or several electrodes.
