摘要
同时考虑乐安河中底泥、悬移质泥沙和推移质泥沙对溶解态重金属进行吸附与解吸,根据质量守恒定律,建立了乐安河重金属污染数学模型并对其进行了求解。对乐安河各断面溶解态铜浓度分布情况的实测值与计算值进行了对比,结果表明公式计算值与实测值比较吻合。
Considering on the absorption and desorption to the dissolution condition heavy metal for the bottom putty,the suspended movement sediment and the bed load movement sediment in Le＇An River,the mathematical model of heavy metal pollution were established and the solution were carried out in this paper.The actual value and the predicted value of dissolution condition copper density distribution in the various cross sections of the Le＇An River were compared and it is showed that the formula predicted values are in good agreement with the actual value.
