【摘要】 基于水沙运动与重金属污染物相互作用关系,结合水体、泥沙颗粒运动与重金属吸附解析附机理以及重金属在水体中的水相、悬浮相、底泥相三种状态,将水动力模型、泥沙输移模型以及重金属迁移转化模型进行耦合,研究了长江重庆江段重金属六价铬的迁移转化及沉积状况。模拟结果表明模型能够合理地反映重金属污染物在水体中的迁移转化过程。更多还原

【Abstract】 Combined with the water-sediment movement mechanism and the heavy metal adsorption-desorption theory in the solid liquid interface,a coupled dynamic model was introduced based on the combination of the hydrodynamic model,the sediment transportation model and the heavy metal migration and transformation model to simulate heavy metal Cr6+ migration.Three different states of heavy mental in water,viz.water phase,suspended phase, sediment phase was considered in the model.The model was used to simulate the heavy mental transformation and cumulation condition of Chongqing Section,Yangtze River.The result shows the model can reasonably reflect the migration and transformation process of heavy mental in water.更多还原
