The electrokinetic remediation (EKR) is a promising technique which is effective to the metal-contaminated soil. This research combined the EKR with a flushing method to remediate the lead-contaminated soil excavated from a factory site. This experiment applied a high potential gradient direct electric field (40.3V/cm) to raise the soil temperature. The high temperature can promote the desorption and migration of lead ions. The desorbed lead ions migrated from top to bottom under the direct electric field and flew into the collection bottle with the eluent in a condition of slight negative pressure. The power consumption was 337Kwh/m3 in 80 minutes. The soil lead concentration decreased from 410±16 mg/kg to 252±10 mg/kg, below the Chongqing soil health risk assessment threshold, meeting the remediation demand. Meanwhile, flushing method also effectively eliminated the focusing effect in the soil near cathode improving the remediation effect.
