| 摘 要： | 首先分析了泥沙在微观和宏观方面,对污染物迁移转化过程中的影响。泥沙通过吸附、解吸作用,同时通过泥沙运动,共同影响着污染物的赋存状态,从而影响着水体环境质量的变化。本文系统总结了在泥沙吸附解吸污染物机理、影响因素、数学模型等方面,已经进行的研究工作所取得的成果,并讨论了有待进一步研究的内容。

| Abstract: | The influence of sediment on transport and transformation of pollutants was reviewed in this paper. Adsorption, desorption and the movement of sediment particles change the form and distribution of pollutants in the natural water bodies. Mechanisms, influence factors, numerical models of pollutants adsorption and desorption by sediments were systematically summarized. Related problems that need further study were discussed based on the present research work. |
