Abstract

Abstract

The remediation and restoration of soil contaminated by heavy metals is considered to be of great significance to the prevention and control of environmental pollution. In this paper, a complex contaminated soil on the surface with Pb and As in a smelter in Henan was taken as the research object. By applying different DC voltages, electrokinetic remediation was carried out. Then based on the mobility and form changes, the restoration effect was evaluated. During the restoration process, we studied the current change, Pb/As migration law, soil moisture content, electrical conductivity, pH value, and Pb/As speciation transformation. The results showed that the change of applied DC voltage had a stronger effect on the migration of Pb in the soil, but a weaker effect on the migration of As. When the applied DC voltage was 10 V, As content in the cathode region of the sample soil was reduced to 43.18 mg/kg; and when the applied DC voltage was 30 V, the Pb content in the cathode region was reduced to 334 mg/kg. The operation of applying low-voltage current first and then high-voltage current was more effective to improve the electrokinetic remediation effect of Pb and As compound contaminated soil. In the restored soil, the proportion of weak acid state of Pb and As decreased, and the proportion of reducible state increased. The content of Pb and As in soil was lower than the screening value for construction land Class Ⅰ in GB 36600—2018.
