| 摘 要： | 淄河滩陈化油污土层是引起大武水源地东部地区地下水污染的主要污染源之一.通过对油污土层采取原状土柱样,在室内进行了模拟淄河滩地存在不同厚度表流时的残油淋溶释放试验.结果表明,在设定的试验条件下,油污土层可淋出水量24.566104m3、油量1185.1kg; 水层厚度对渗出水的油浓度影响不大,渗出油的多少主要决定于渗出水的数量;太河水库放水补源方式对残油释放量的影响不起决定性

| Abstract: | The layer of crusted oil-contaminated soil in Zihe riverflat is one of the main contamination sources that cause the pollution of groundwater in the east part of Dawu water supply. By taking an undisturbed column sample ofoil-contaminated soil, authors studied the indoor experiment for the purpose of simulating the release of residual oil when surface water of different thickness exists on Zihe riverflat. The results indicate that 245.66 thousand m3 water and1185.1kg oil can seep through the layer of oil-contaminated soil under the experiment condition given. The waterthickness has little influence on the oil concentration of seeping water. The released oil amount mainly depends on theseeping water amount. The recharge manner of Taihe reservoir water has no decisive effect on the amount of residual oil released. |
