| 摘 要： | 生物处理是一种经济有效处理土壤水环境中有机污染物的手段，本文在研究土地生物处理过程的基础上，建立了综合描述有机污染物在土壤－水－微生物系统中扩散、吸附／解吸、屏蔽和生物降解过程的数学模型。为确定模型中各参数在模型计算中的作用和相对重要性，进行了参数灵敏度分析，预计数学模型可以定量预测有机污染物进行土地生物处理所需的要时间和程度，为构建土地生物处理工程提供参考。

| Abstract: | Biodegradation process is an economical and effective way to degrade organic chemicals in remediation sites. Based on the intensity study about chemical's degradation processes, a comprehensive mathematical model, which describes chemical's diffusion, sorption/desorption, sequestration, and biodegradation in soil water microbes system, has been developed in this paper. A sensitivity analysis was performed to assess the effect of several parameters on model behavior. It is noteworthy that the chemical's concentrations in soil, in particle water phase, in bulk water, as well as the necessary remediation time can be predicted by using this model. |
