IN SITU REMEDIATION OF SOILS AND GROUND WATER CONTAINING ORGANIC CONTAMINANTS

摘要

There is provided a method for achieving oxidation of organic contaminants held in low permeability soil and its contained pore water. The method comprises the supply and electromigration of an oxidant throughout the soil and pore water by means of an applied direct current via electrodes arrayed within the soil, followed by the heating of the soil by an applied alternating current using the identical electrodes.

主权项

1. A method for the remediation of contaminated soil comprising:
adding a heat-activated oxidizing agent into the soil, such soil including pore water; exposing the soil to direct current through electrodes so as to cause migration of the oxidizing agent through the soil and pore water; and exposing the soil to alternating current through electrodes so as to heat the soil and thus to activate the oxidizing agent.
