For lead-zinc contaminated soil, the principles, characteristics and application of traditional soil remediation were summarized, such as solidification/stabilization, electromotive method, phytoremediation and biological methods. The feasibility of tartaric acid washing of soil contaminated by Pb and Zn was studied. It demonstrated that it is feasible to remediate the soil contaminated by Pb and Zn by tartaric acid washing. The content of Pb and Zn in the residual soil achieved the National Soil Environmental Quality Standards.
