摘　　要：地下水一旦被污染,很难恢复到原来的状态,污染物泄漏后,如何最大程度地减小污染物在地下水中运移具有十分重要的意义。从此方向出发,探讨在地下水污染物瞬时大量泄漏情景下,减小地下水污染运移的因素,研究结果表明:减小含水层渗透系数(物理屏蔽法)最为有效,超标污染减小可达78%;减小含水层水力坡度(抽出处理法)效果稍逊,超标污染减小程度可达68%;增加含水层厚度(水动力处理法)效果较差,超标污染减小程度为53%。Once groundwater is contaminated,it is dif-ficult to restore it to the original state.After the pollut-ants leak,how to minimize the transport of pollutants in groundwater is of great significance.Starting from this direction,this paper discusses the factors that reduce the transport of groundwater pollution under the scenario of instantaneous large-scale leakage of groundwater pol-lutants.The research results show that reducing the perme-ability coefficient of the aquifer(physical shielding meth-od)is the most effective,and the excessive pollution can be reduced by up to 78%;reducing the aquifer hydraulic gradient(extraction treatment method)is slightly less ef-fective,and the reduction of excessive pollution can reach 68%;and increasing the aquifer thickness(hydrodynamic treatment method)is less effective,and the reduction of excessive pollution is 53%.
