Abstract采用室内石英砂柱出流实验和数学模型,研究了流速对自然土壤胶体、蒙脱石胶体和腐殖酸钠胶体在饱和多孔介质中运移的影响。结果表明:孔隙水流速影响着胶体在多孔介质中的运移过程,流速的提高可加速土壤胶体的出流过程,减小蒙脱石胶体和腐殖酸钠胶体的沉积率。胶体的运移过程除受孔隙水流速的影响外,胶体特性的不同亦决定着胶体运移过程的差异,由于胶体表面性质不同,与介质之间的作用力不同,决定了胶体运移过程中的沉积和释放。
Other AbstractThis study investigated the effect of flowrate on the transport of nature soil colloid,montmorillonite colloid and sodium humate colloid in saturated porous media with simulating lab experiments.The result showed that the pore water affected the transport of all colloids in porous media,and the increase of flowrate could accelerate the process of outflow of soil colloid,and the increase of flowrate could decrease the deposition rate of montmorillonite colloid and sodium humate colloid.Bescides the effect of...
