地下水受原油污染的问题日益受到人们的重视。根据我国几个主要油田的地下水样测试结果,分析筛选出了易进入地下水中迁移的有代表性的有毒有害原油组分(如苯系物等)。从原油组分的性质与老化、污染途径、水文地质条件对污染的影响等方面讨论了原油组分对地下水的污染机理。基于污染机理提出了防治原油组分污染地下水的对策。
The problem of groundwater polluted by crude oil has been paid more and more attention by people. According to the groundwater sample test results of several major oilfields in China, the representative toxic and harmful crude oil components (such as benzene series) that are easy to migrate into the groundwater are screened out. The pollution mechanism of crude oil components to groundwater is discussed from the aspects of the nature and aging of crude oil components, the route of pollution, the impact of hydrogeological conditions on the pollution and so on. Based on the pollution mechanism, the countermeasures of controlling the pollution of groundwater with crude oil components are proposed.
