Abstract
An apparatus for remediation of a copper and nickel co-contaminated soil includes a housing. A crushing device is arranged at the upper part of the inside of the housing. A stirring device is arranged below the crushing device. An anode electrode and a cathode electrode are provided at both ends of the inner bottom of the housing, respectively. In the present invention, the soil contaminated by copper and nickel is first poured from the top of the crushing device, and then crushed thoroughly under the action of the crushing device. The crushed soil facilitates the movement of copper and nickel metal ions therein toward the electrodes under the action of the anode electrode and the cathode electrode, thereby achieving optimal soil remediation.
