| 摘 要： | 根据PRB原理，考虑对流作用、弥散作用、吸附作用、化学反应等因素对溶质运移的影响，设计了连续反应单元. 结果表明，对流作用对溶质运移速度影响较大，吸附作用与化学反应对污染物的去除影响较大. 分析了地下含水层水力传导系数(Kaquifer)及连续反应单元内的水力传导系数(Kcell)对溶质运移的影响. 结果表明，地下含水层Kaquifer较小(Kaquifer为1和5 m/d)时，Kcell取值对溶质运移总量影响不大；当Kcell∶Kaquifer≥10时，增加Kcell值对促进溶质运移作用较小.

| Abstract: | In this study,a continuous reactive cell was designed according to the PRB technology principle.Convection,diffusion,absorption,chemical reactions,and other factors which affect the solute transmission were studied by this method,and three different schemes were simulated.The results show that convection plays an important role in the solute transmission speed.Absorption and chemical reactions play an important role in the pollutant removal.The infection of solute transmission affected by groundwater aquife... |
