| 摘 要： | 简要分析尾矿渗流污染过程,尾矿坝体是主要渗流治理对象,运用传质原理,引入尾矿废水与污染物之间的曳力系数,提出污染物传质速度与废水速度计算公式,进而改进浸润线计算公式,利用Gambit软件建立了尾矿坝渗流的二维几何模拟模型,将尾矿坝内部的尾粉砂和尾粉土理化特性常数输入Fluent模拟多孔介质模式,模拟废水在其中的流动状态,对比分析污染物在尾矿坝的污染情况.依据模拟结果,分析了尾矿坝废水速度场和压力场,结合公式推测污染情况和浸润线变化.

| Abstract: | This paper briefly analyzes the polluted process of tailings seepage.Mass transfer principle is applied to introduce drag coefficient between tailings waste water and pollutants and put forward the formula of pollutants mass transfer rate and wastewater flow rate,and then the formula of saturation line is modified.Two-dimensional geometric simulation model is established by gambit software,and physical and chemical parameters of tailings silty sand and silt soil are input to the model of porous media by fluent,in which the waste water flow state is simulated and the pollution in the two conditions are compared.Based on the simulation results,analyses on water velocity and pressure field are conducted,changes of pollution and invasive lines are suggested combined with the formula. |
