摘要： Method and system for soil remediation by flash Joule heating. A contaminated soil that includes organic pollutants and/or one or more metal pollutants can be mixed with carbon black or other conductive additive to form a mixture. The mixture then undergoes flash Joule heating to clean the soil (by the decomposing of the organic pollutants and/or removing of the one or more toxic metals, such as by vaporization).

摘要： A method for in-situ soil remediation is provided. Electrodes are placed below the ground surface extending horizontally. The electrodes are positioned such that a first electrode is positioned above a second electrode and the electrodes surround a region of soil containing contaminants. A plurality of electrodes can be placed in an upper plane corresponding with a plurality of electrodes placed in a lower plane. By passing a current between the electrodes contaminants are mobilized towards the electrodes where the contaminants can be extracted. The electrodes are constructed by boring substantially horizontal bore holes, inserting a well screen in the bore hole and packing an annulus formed between the well screen and the bore hole with electrically conductive particulate matter.
