摘要
通过分析研究厂区包气带土层石油污染物的检测结果(包括总油和苯含量),认为该区西南角地下设施石油污染物的持续泄漏是影响下游地下水供水质量的重要污染源,而金岭断裂则是污染物侵入含水层的重要通道.石油烃化合物在包气带迁移过程中具有(1)扩散、挥发、淋滤作用,(2)吸附,(3)生物降解,(4)向地下水中迁移,及(5)形成残油体等归宿.
The paper discussed the distribution of petroleum contaminants,such as total oils and benzene, in the unsaturated zone in the studied area. The continuous leakages of petroleum contaminants from underground pipes buried under the southwest corner of the area were important sources polluting groundwater down hydraulic gradient. Jinling fault is an important path where petroleum contaminants move to the aquitfer. The hydrocarbon fates in the transport processes are (1)dispersion, volatilization and leaching; (2)absorption, (3)biodegration, (4)entering into saturated zone, (5)residual oils, etc.
