铬在包气带的垂直污染机理研究

宋国慧  史春安 

摘 要:通过铬在包气带的垂直渗滤试验探讨了铬对地下水污染的机制,认识到地下水铬污染的主要途径是通过包气带渗入,铬在包气带中的垂直迁移性好,铬进入含水层后,在水动力条件及浓度的影响下,可发生运移—弥散作用,造成大面积地下水污染,严重影响生态环境。

AbstractThis paper researches the source of chrone pollution in unsturated zone.By investigating the chrome pollution in Tai Bai Xian, the vertical penetration experiment in the unsturated zone .Based on the resust of the experiment the author probes into the machanism of chrome pollution and thinks the approach of underground water chrome pollution is that chrome penetrates into water through unsturated zone. Because the wandering feature of chrome is fine and under the influence of hydrodynamic and concentration gradient in the aquifer it can be wandered-diffused,which results in underground water pollution in large area.It muxt bring influence on evological enviroment.
