【摘要】 采用谐振式紊动模拟装置使污染泥沙受到扰动，解吸重金属污染物进行模拟试验研究。在此基础上，由极坐标下的重金属迁移转化数学模型方程，针对具体的试验条件进行数值求解。计算和试验结果吻合良好。说明数学模型是正确合理的。计算中采用由静态试验得出的泥沙吸附－解吸特性参数，这对于评价静态试验成果，利用静态试验成果于天然河流水体具有一定的参考价值。更多还原

【Abstract】 Desorption of sediment polluted by heavy metals is studied by using harmonic vibration device for simulating turbulence.By establishing a mathematical model of heavy metals transport andtransformation under polar coordinates,a numerical solution for concrete experiment condition ismade.The identical results between measured and calculated ones are obtained.It is clarified that themathematical model established in this paper is correct and rational.Characteristic parameters of sediment adsorption-desorption obtained in static experiment is used in calculation.This is valuable tosome extent for estimating and using results obtained in static experiment to natural rivers.更多还原
