贴不贴泡石油污水对地下水的污染分析

贴不贴泡是大庆某石油化工总厂生产废水排放场地,其作用相当于一个水面较大的氧化塘。本文对大庆市贴不贴泡周边地下水采集样品,以研究其对周边地下水的污染状况。结果显示:纳污泡附近地下水受到不同程度石油类污染,石油类污染物还仅限于湖泡区内,在剖面上的分布基本限于潜水层内,局部达到弱透水层顶部附近。石油类污染物在其中的迁移速度很低,特别是水平迁移速度更小,才使污染近30年的场地地下水受到的石油烃污染不是十分严重。

Analysis on Groundwater Polluted by Oil Sewage in Tiebutie Pool

The petroleum pollution has become a serious environmental problem.Tiebutie pool,which takes wastewater discharge from a petrochemical plant in Daqing,plays the role of wide oxidation pond.In order to investigate the groundwater pollution around the pool,groundwater samples were collected from around the pool.The results show that the groundwater near the pool was slightly polluted by petroleum.The petroleum pollutants are restricted in the lake,which is basically restricted in the diving level in the section plane distribution,reaching the top of weak permeable bed partially.The petroleum pollutant moves slowly,especially in horizontal move,which prevents the groundwater from serious pollution in nearly 30 years.
