Title:
SYSTEM AND METHOD FOR REMEDIATION OF ORGANIC CONTAMINATED SOIL
Document Type and Number:
WIPO Patent Application WO/2010/081291
Kind Code:
A1
Abstract:
A system and a method for remediation of organic contaminated soil are provided, which comprises M*N electrodes to form an electrode matrix of symmetrical electric field structure. The field intensity is uniform in those points that are equidistant from each electrode in remediation area. The electrodes arrayed in mesh style in remediation area are carried out electrokinetic remediation. To exchange between positive polarity and negative polarity of the electrodes periodically is to make each electrode be a state of anode intermittently which has preferable remediation efficiency, by operation mode of reversing row/column electrode groups in manner of electrical scanning.
