| 中文摘要: |
| 本文建立了描述场址区含水层中TCA污染运移的数学模型，采用有限差分法求解。假定场址区水流呈稳定态，而溶质运移呈非稳定态。数值模拟结果表明，持续去污条件下含水层中TCA污染羽状体的分布范围及其浓度均有明显的减小，三年之后，其去污效率达80%以上。因而认为，抽出处理方案于本实例中的应用是成功的。场址污染含水层介质的较强的水力传导性是其主要的有利因素。 |
| 英文摘要: |
| A mathematical model describing TCA transport in an aquifer at an industrial site is solved by using GMS software package.It is assumed that the groundwater flow at the site is in steady state,while the solute transport is in unsteady state.Results obtained from the numerical simulation indicate that their is a net reduction both in concentration of TCA and in extent of the plume during the period of operaton.After continuous operation for three years the remediation efficiency reaches more than 80%. |
