ENERGY-EFFECTIVE ELECTROKINETIC REMEDIATION SYSTEM USING ON-OFF POWER

摘要

PURPOSE: A power reducing type electrokinetic soil purifying method is provided to maintain soil purifying performance and reduce power consumption by periodically repeating the supplying state of power. CONSTITUTION: A power supplying unit(10) fixes a positive electrode part(20) and a negative electrode part(30) at opposite positions. Contaminated soil is arranged between the positive electrode part and the negative electrode part. The positive electrode part supplies an electrolytic solution. A power supplying process continuously repeats power-on time and power-off time. The power-on time and the power-off time respectively maintains for 1 to 2 seconds. In the power supplying process, the current density of power is between 0.1mA/cm^2 to 10mA/cm^2 or the voltage slope of the power is between 0.1 and 10V/cm.
