河流水体中重金属形态模型研究
RESEARCH ON MODELING OF HEAVY METAL SPECIATION IN LEAN RIVER
-
摘要: 本文提出了一种重金属形态模型,用于模拟水体中的水溶态、颗粒态和底泥、悬浮物的活动态和非活动态。以乐安江水体中铜污染为背景,计算结果与现场调查分析的数据比较表明,两者基本吻台,说明模型基本上是合理的,概括了重金属污染的重要过程,参数的选择反映了河流的实际情况。Abstract: A model of heavy metal speciation in water system is proposed. It can be used to simulate dissolved, particulated species in water column and active, inert part in sediment and suspension. Comparison of calculation data and field data indicates that the changing tendency of metal concentration in sediment and water column is in accordance with each other, the model describes reasonably the main transport processes of heavy metal contamination between water column and suspension sediment. Estimation of model parameter is responsible for the situation of Lean river.
