Abstract
Disclosed is an electrokinetic-aeration-liquid injection combined remediation method for compound contaminated soil containing heavy metals and organic substances, and belongs to the field of contaminated soil remediation. According to the present application, in the combined remediation method, the electrokinetic remediation method enables water in soil to migrate from bottom to top to drive heavy metals and organic substances to be enriched towards the top; bubbles generated by the aeration method are diffused from the bottom to the top to drive volatile organic compounds to move towards the top soil. During liquid injection process, the electrolyte is driven to move from bottom to top under the action of electrokinetic remediation flow, which can keep the pH of the soil stable and remediate heavy metals and organic pollutants. The whole processes are simultaneously completed by adopting the dual-channel porous EKG electrode designed by the present application, which is efficient and convenient.
