| 摘 要： | 对含沙水体中的吸附质污染物输运过程进行分析,从单元体出发推导考虑泥沙影响的污染物输运方程。导出的方程考虑了冲刷沉降、孔隙水扩散和孔隙水混合作用的影响,并应用于灌河口的TP浓度计算,验证结果较好。

| Abstract: | The sediment-associated processes,which affect the adsorptive contaminant fluxes,include the near-bed particulate pollutants exchange due to the sediment erosion and deposition,pore water diffusion,and due to the dissolved pollutants concentration gradient and pore water advection.An adsorptive contaminant transport equation including the processes mentioned above is deduced in theory.The equation is solved to simulate the phosphorus concentrations in Guanhe Estuary in China.The simulated phosphorus concentrations show better agreement with observation in the field. |
