A two-dimensional numerical model considering cation exchange and surface complexation reactions for the remediation of heavy metal contaminated soil by acid flushing is developed. The CIP scheme and chemical equilibrium calculation are used to solve the model. To understand the two-dimensional flow condition effects, numerical simulation of lead contaminated soil remediation is performed. The results show that concentration of adsorbed lead displays heterogeneous distribution because of the repeated adsorption and desorprion and acid-injection position. The outflow position should have the same height in order to be effective. The proposed model is useful to evaluate the design for remediation of heavy metal contaminated soil by acid flushing.
