摘要:
针对2005年12月发生在北江流域的重金属镉污染事故,建立了一维河流重金属迁移转化模型,结合污染事故实测资料,对模型进行了参数率定和验证.从计算结果来看,当水体中镉浓度值较大时,重金属模型计算值与实测值拟合效果较好,而镉浓度值较低时,则拟合效果不理想,此外,水体中镉浓度随着水流运动由上游向下游递减,这说明重金属在吸附、沉降作用下逐步沉积到底泥中.
Abstract:

Aiming at the heavy metal cadmium pollution accident in the Beijiang River Basin in December 2005, a one-dimensional river heavy metal migration and transformation model was established, and the parameters of the model were determined and verified by combining the measured data of the pollution accident. From the calculation results, when the cadmium concentration value in the water body is large, the calculated value of the heavy metal model fits well with the measured value, while when the cadmium concentration value is low, the fitting effect is not ideal, in addition, the cadmium concentration in the water body decreases from upstream to downstream with the movement of the water flow, which indicates that the heavy metal is gradually deposited in the bottom mud under the action of adsorption and sedimentation.
