| 摘 要： | 本文以水体中重金属(包括溶解态和颗粒态)的物理迁移过程为基础,建立重金属迁移扩散的数学模式。模式中考虑悬浮物沉降和再悬浮对水体中重金属浓度的影响,并考虑咸潮活动引起悬浮物的絮凝沉淀作用。计算结果表明,这种潮汐河口区重金属迁移扩散模式基本上是成功的。并以镉为例,说明重金属在西江河口区迁移扩散的特点。

| Abstract: | Based on the process of physical transportation,a mathematical model of transportation and diffusion of heavy metals (including dissolved and suspended forms) is developed, in which the processes of deposition and resuspension of suspended particulate matter (SPM) as well as the influence of coacervation caused by salt water on SPM are considered. The result of the simulation shows that this kind of model for transportation and diffusion of heavy metals in tidal estuaries is basically successful.Finally, we have taken Cadmium as an example to show the characters of transportation and diffusion of heavy metals in the Xijiang River Estuary. |
