| 摘 要： | 在污水灌入土柱试验的基础上,用自来水代替试验配水,模拟污染河流还清后对地下水的影响。试验结果表明:清水回灌会很明显地把污染河流下部渗透介质中的COD,NH4+带到地下水中,造成地下水污染,其进入地下水的量取决于渗透介质中截留的COD和NH4+的量;清水回灌仅会把河床下部渗透介质中少量的Cr(Ⅵ),TP和苯系物带到地下水中,成为地下水有机污染的一个来源;Pb2+一般不会被带到地下水中。 |
| 关 键 词： | 污染河流 清水回灌 地下水 |

| Abstract: | Based on the experiment of sewage penetrating through sands,clean water was used instead of sewage for simulation of the influence of polluted river flushing on groundwater.The results show that COD and NH~ _4 in the penetration media in the river bottom are obviously carried into groundwater.The amount of COD and NH~ _4 in groundwater depends on that intercepted by penetration media. Part of Cr~(6 ),TP,BTEX and none of Pb~(2 ) are taken into groundwater,which becomes a source of organic pollution in groundwater. |
| Keywords: | polluted river clean water leaching groundwater |
