數學模式常用來模擬污染物於土壤與地下水的宿命與傳輸，三維多物種傳輸解析解模式為預測核種、溶解含氯有機溶劑、氨氮與殺蟲劑等衰降性污染物污染團行為的基本有效率的工具，大部份的多物種傳輸解析解模式考慮線性平衡吸附過程，然而使用線性平衡過成常被質疑無法解釋地表下污染物傳輸過程可能的非平衡吸附過程。本計畫為兩年期產學合作計畫，我們與「業興環境科技有限公司」合作開發考慮非平衡動力吸附過程的先進三維多物種傳輸解析解模式做為快速預測衰降性污染物污染團行為工具，計畫第一年將發展邊界污染源的非平衡之動力吸附解析解模式與其對應的計算程式，計畫第二年將發展多內部污染源的非平衡之動力吸附解析解模式與其計算程式，整合兩年計畫的成果可建立先進的模式工具(MUSTAM)做為準確預測三維地下水污染物污染團行為的工具。 ;Mathematical model is widely used to simulate the fate and transport of contaminants in soils and groundwater. The three-dimensional multispecies transport analytical model is an essential and efficient model tool for predicting the plume behavior of decaying contaminant such as radionuclides, dissolved chlorinated solvents, nitrogen and pesticides. Most of the multispecies analytical models are derived subject to a linear equilibrium sorption process. However, the use of equilibrium sorption model has been frequently questioned as it cannot adequately account for nonequilibrium sorption process during the contaminant transport in subsurface environment. In this two-year industry-academy cooperation project, we collaborate with the Sinotech Environmental Techonology, Ltd. to develop advanced three-dimensional analytical models for rapidly predicting the plume behavior of decaying contaminants in the groundwater system subject to a nonequilibrium kinetic sorption process. In the first year, a three-dimensional analytical model for boundary sources and its corresponding computation code will be developed. In the second year, we will extend the development of the three-dimensional analytical model and its computation code to multiple internal sources. The results from this two-year project can be integrated to build an advanced three-dimensional model tools, namely, MUSTAM (Multi-Species Transport Analytical Model), for accurately predicting the plume behavior of groundwater contaminants.
