摘　　要：黄河水中,细颗粒悬浮物吸附痕量有机污染物,采用常规水处理技术,效果不佳。利用地面渗水法进行浅层地下水的补给,可以有效改善黄河水水质。利用砂柱试验模拟地面渗水法补给地下水过程中有机污染物的迁移过程,将黄河供水优先控制的阿特拉津作为污染物,黄河水所含黏土矿物中比例最大的蒙脱石作为胶体,进行痕量有机物在饱和稳定流非均匀孔隙介质中的迁移试验,结果表明:胶体蒙脱石对有机污染物阿特拉津在砂卵砾石层的迁移有一定促进作用;采用平衡和非平衡模型对试验结果进行拟合,拟合效果较好,说明该模型可以用来预测分析与胶体有关的有机污染物在饱和稳定流非均匀多孔介质中的迁移。Fine particle suspensions in the Yellow River water adsorbs trace organic pollutants and conventional water treatment technology is less effective to it. The Yellow River water replenishes the aquifer through water spreading and then extracts the water,which can effectively improve the water quality of the Yellow River. This study used sand column experiments to simulate the migration process of organic pollutants in the water spreading process. Atrazine,which is priority controlled by the Yellow River water supply was used as a pollutant. Montmorillonite,the largest proportion of clay minerals in the Yellow River water was used as colloid. This study simulated the migration test of trace organic pollutants in a non-uniform porous medium with saturated steady flow. The results show that colloidal montmorillonite can promote the migration of atrazine in sand gravel layer. Balance and unbalance models can be used to predict the migration of colloid-related organic contaminants in a saturated and stable flow in a non-uniform porous medium.
