摘要
本文首先分析了地下水中石油类污染的时空分布规律，在此基础上，布置了水力截获工程．水力截获带运行后的结果表明，水力截获技术可以去除地下水中的部分石油类污染物．另外，还对水力截获带运行期间地下水中石油类污染物的运移做了数值模拟，特别是对污染源切断前后地下水中石油类污染物的时空分布规律进行了预测．最后，得出如下结论：（１）查清研究区的水文地质条件是布置治理工程的前提，（２）切断污染源是有效治理的关键．
The temporal and spatial distributions of petroleum contaminants in ground water are dealt with in this paper. On this basis, hydraulic capture engineering is arranged. The results from running the hydraulic capture wells show the partial petroleum contaminants in groundwater maybe removed out by the hydraulic capture technique. The transport of contaminants during running the hydraulic capture wells is modeled as well. Specially, the temporal and spatial distribution of petroleum contaminants in ground water before and after cut the contaminant sources off is predicted. At last, the conclusions can be come to as follows:1 The prerequisite of arranging remedial engineering is to ascertain the hydrogeological conditions in studied region, 2 The capture zone is an efficient method for the remedy of contaminated fracture karst water.
