Title: FIELD INTENSITY COMPENSATION METHOD OF CONSTRUCTING NON-UNIFORM ELECTRIC FIELD BY MEANS OF AUXILIARY ELECTRODE
Abstract:
The present invention relates to a field intensity compensation method of constructing a non-uniform electric field by means of an auxiliary electrode, comprising the following steps: designing a deployment position of an auxiliary electrode in a matrix electrode unit according to spatial distribution of pollutant concentration; designing the polarity of the auxiliary electrode according to a positional relation between the auxiliary electrode and matrix electrodes; and constructing a non-uniform electric field by means of the auxiliary electrode and the matrix electrodes, thereby implementing spatial compensation on intensity of the electric field. In the present invention, on the basis of matrix electrodes, the present invention constructs, a non-uniform electric field matching a pollutant concentration field is constructed by means of spatial deployment and polarity setting of an auxiliary electrode according to spatial distribution of pollutant concentration, thereby overcoming the contradiction between the heterogeneity of spatial distribution of pollutants and the removal efficiency consistency of a uniform electric field, and avoiding the spatial difference of electrokinetic remediation efficiency of organic contaminated soil, so that the overall spatial electrokinetic remediation efficiency is improved.
