摘　　要：采用自行设计的室内土柱实验装置来模拟渭河渗滤系统,定性研究受苯胺污染的河水在渭河渗滤系统中的环境行为及净化机制,其环境行为包括吸附作用和生物降解作用。用数学模型定量模拟苯胺在渗滤系统中的环境行为,建立苯胺迁移转化的数学模型,通过求解参数得到苯胺的确定性迁移方程,分别预测了不同时间、不同深度苯胺相对浓度的变化情况。用模型预测的结果与实测结果相比吻合较好,证明了苯胺数学模拟与所求参数可信。A set of laboratory experiment instruments of soil coluran were designed to simulate the filtration system in Weihe River. The environmental behaviors, including adsorption and biodegradation, and purification mechanism of aniline-polluted river water were studied qualitatively. Mathematical models were established to simulate the transportation and transformation of aniline and the environmental behavior of aniline in river filtration system quantitatively. The transportation equation of aniline was given through the solution of parameters. The prediction results of the variation of relative concentration of aniline at different depths and time ware in agreement with the field data, showing that the mathematical model and parameters are reliable.
