| dc.description.abstract | 含氯有機溶劑為地下水中常發現的污染物，其中四氯乙烯及三氯乙烯為台灣及其他先進工業化國家地下水污染場址中常見的含氯有機污染物。過去研究顯示，同時進行污染源區以及溶解相污染團的整治可以更直接且有效的利用有限的資源進行地下水污染整治。然而，過去大多數的污染整治評估模式，都只適用於原始污染物(母物種)和它的降解的副產物(子物種)採用相同的遲滯因子。本研究提出了一個可以同時考慮污染源區以及溶解相污染團的含氯有機溶劑地下水污染整治評估全新的解析解模式，模式可以考慮每一個污染物有不同的遲滯因子。所發展的模式與文獻中的半解析解比較，結果顯示兩者非常的吻合，確認解析解與其計算FORTRAN程式的正確性與準確性。然後，應用所開發的解析解模式探討在進行整治工作後，遲滯因子對溶解相污染團的遷移影響。本研究所開發的模式可以更深入的了解可能的污染場址現地整治技術與整治管理方針，以各種整治技術的組合對於地下水污染整治成效的影響，並量化這些整治方法的效益。 | zh_TW |
| dc.description.abstract | Chlorinated solvents are the most common groundwater contaminants. The PCE (tetrachloroethene) and TCE (trichloroethene) are the most common chlorinated solvents pollutants in Taiwan and other advanced industrialized countries. Research shows that remediation technology applications to coupled source and plume can directly lead to more efficient use of limited resource. Most of the remediation evaluation models are applicable for the field situations that the contaminant and degradation byproducts have identical retardation factors. In this study, we propose a novel analytical model that couples source and dissolved plume zone remediation of groundwater contaminated with chlorinated solvents. The biggest development of this model will be valid for different retardation factors for each individual species. The correctness of the mathematical model and its auxiliary FORTRAN computer program code are established with excellent agreements of simulated downgradient plume concentration of all contaminants produced from the derived analytical model and a semi-analytical model available in the literature. Subsequently, the developed analytical model is used to illustrate how the retardation factors affect downgradient plume migration after remedial efforts. The developed model is used to better understand the impacts of various combination of possible remedial technologies and management decisions on the subsurface contamination and quantify the benefit of these treatment technology. | en_US |
