Electrokinetically-Enhanced Contaminant Transport Mechanism

在这个项目中，将研究电动增强污染物在土壤中迁移的瞬时化学和物理过程，以开发一种适用于复杂土壤污染情况的预测工具。调查分为两个阶段：实验室工作和分析工作。在实验室工作中，被重金属和有机物污染的模拟土壤样本将接受长期的电动测试。在这项工作的分析阶段，现有的土壤中溶质保留和运移的二级动力学方法模型将与一个现有的专家系统外壳对接，并增加新的数据和基本规则。将开发一个原型系统，随着pH、氧化还原电位和土壤保持容量在时间和空间上的变化，以时间步长更新算法模型的初始条件。

In this project the transient chemical and physical processes during electrokinetically enhanced contaminant transport in soils will be investigated to develop a predictive tool that could be applicable to complicated situations of soil contamination. The investigation is composed of two phases: laboratory work and analytical work. In laboratory work, simulated specimens of contaminated soil with heavy metals and organic substances will be subjected to long term electrokinetic tests. In the analytical phase of the work, an existing model of second order kinetic approach for solute retention and transport in soils will be interfaced with an existing shell of an expert system augmented with the new data and base rules. A prototype system will be developed which updates the initial conditions of the algorithmic model in time steps as pH, redox potential, and soil retention capacity changes in time and space.
