Method for removing Pb and Cr in mine tailings by using saturated mine tailing solution-reinforced electrokinetic remediation technology

摘要: The invention relates to a method for removing Pb and Cr in mine tailings by using saturated tailing solution-reinforced electrokinetic remediation technology, belonging the field of environment protection technology. comprises following steps: heating boiling deionized water, then cooling water subsequent usage, preparing an ascorbic acid solution with concentration 0.1 0.4 mol/L from treated citric according mol ratio 1: 1 6: 1; adding into earth pillar saturation 8 15 h subjecting having undergone remediation, wherein positive negative electrodes are both graphite electrodes, electrode electrolyte is pH value adjusted 4 acid. According method, added on basis controlling electrolysis chamber so as convert weak-acid extraction states; has high efficiency highly-acid buffering capability.
