| 摘 要： | 通过对下水油类浓度、水位、降雨量及色质联机分析，确定了包气带中残油为水源地主要污染源之一，利用动态释放试验。模拟了河滩包气油污土层中残油动态释放过程，探讨了不同水深及间歇进地油类释放的影响并确定残油的污染能力。

| Abstract: | The residual oil in unsaturated zone was determined to be one of the main pollution sources by analyzing hydrological and hydrogeological conditions,and organic components in groundwater,polluted and wastewater.The dynamic stimulation results indicate that a rapid phase and a slow phase exist in the release process.The release amount under continuous condition in the first day was 382.05mg(oil)/kg (soil),and 843.03mg(oil)/kg (soil) in 7 days.The average release rate in 7 days was 120.40mg (oil)/kg (soil)·day.In constrast with continuous process,the efflux through intermittent column reduced while the oil concentration increased.The increment was 26.61mg(oil)/kg(soil) in one day intermission and 237.65mg(oil)/kg(soil)in 7days. |
