摘要：

A 3D model was constructed to optimize the remediation scheme of groundwater environment which was contaminated through leaching from the municipal solid waste landfill. Based on groundwater sampling test results, potassium permanganate index (CODMn) was selected as a pollution indicator with high concentration. Two scenarios were predicted in this study. Scenario 1 is assigned for the combination of a horizontal landfill barrier covers by high-density polyethylene (HDPE) and monitored natural recovery (MNR). Scenario 2 is resulted from the combination of horizontal and vertical barrier technology and pumping treatment (P-T). The results showed that the leachate could be well controlled by Scenario 2. Applying of Scenario 2 plays an important role of restoring the quality of groundwater to its nature after 2000 days as compared to Scenario 1, which needs more than 6000 days. The usefulness of anti-seepage measures regarding leachate control in landfill has been put forwarded, and findings could be applied according to the evaluation of actual contamination sites. This study will provide a scientific basis to utilize the groundwater resources sustainably in the study area.
