基于水泥随入渗污水潜入河床淤泥模拟试验，分析了水泥潜入对污水中重金属锌的阻截作用，揭示了污水所含重金属锌沿深度方向的变化特性。结果表明：水泥潜入河道淤泥可以有效阻截重金属锌在土壤中的纵向迁移；在一定范围内，土壤阻截重金属锌的作用随着水泥潜入量的增大而增大；在水泥潜入的条件下，重金属锌的表聚作用明显，即土壤阻截重金属锌的作用随深度的增大而减小。
基于水泥隨入滲汙水潛入河床淤泥模擬試驗，分析瞭水泥潛入對汙水中重金屬鋅的阻截作用，揭示瞭汙水所含重金屬鋅沿深度方嚮的變化特性。結果錶明：水泥潛入河道淤泥可以有效阻截重金屬鋅在土壤中的縱嚮遷移；在一定範圍內，土壤阻截重金屬鋅的作用隨著水泥潛入量的增大而增大；在水泥潛入的條件下，重金屬鋅的錶聚作用明顯，即土壤阻截重金屬鋅的作用隨深度的增大而減小。

Based on a series of tests on cement's infiltration into the simulated soil column together with infiltration wastewater,this paper an-alyzed the cement sneak carrying heavy metals in sewage interdiction role of zinc Zn,revealed the changing characteristics of wastewater con-taining heavy metals zinc along the depth. Tests show that the method of cement filters into the topsoil with seepage water can effectively pre-vent the migration of zinc in soils. At some extend,this retaining effect is amplified with the increase of cement volume while diminishes with the increase of soil column depth. Under the conditions of cement sneak,the function of heavy metals zinc sheet dimerization is more obvi-ous,i. e. it decreases sharply with increasing depth of soil column of Zn accumulation.
