Abstract

Abstract: Taking chromite ore processing residue site in Shenyang city of Liaoning province as a research object, the static adsorption experiment and the dynamic soil column experiment were carried out, and the adsorption characteristics and the migration law for hexavalent chromium of chromite ore processing residue leachate were analyzed in the groundwater system. A coupled dynamic mathematical model was developed for simulating hexavalent chromium migration in the groundwater system. Numerical simulation of hexavalent chromium migration in groundwater for 40 years before the anti-seepage measure and for 60 years after the anti-seepage measure was completed by using Visual Modflow software. The field groundwater monitoring data of water quality was used to provide a quantitative verification. The results indicate that numerical simulation results of hexavalent chromium concentration agree with the monitoring data more or less, which verifies the model is reliable and practical.
