摘    要:以辽河油田某采油废水处理厂外排水中石油类污染物为对象,对比分析了不同季节条件下河流中石油类污染物的迁移特征,估算了石油类污染物不同归宿途径的贡献率.结果表明,不同季节条件下,河流中石油类污染物浓度的减少与迁移距离呈显著负相关,但各族组成(烷烃组分、芳烃组分、极性物质)的浓度与比例变化的季节差异显著;冬季河流中石油类污染物的主要归宿途径为沉淀作用(39.5%)与迁移输出(60.5%);以冬季沉淀作用为参考,夏季河流中石油类污染物的主要归宿途径贡献率分别为39.5%(沉淀作用)、42.4%(降解作用)18.1%(迁移输出),且污染物族组成的各归宿途径贡献率差别明显.

关 键 词:石油类污染物  归宿  沉淀  降解  族组成

Abstract:Taking the petroleum pollutants discharged from an oil wastewater treatment plant in Liaohe Oilfield as research objects,this paper analyzed their fates in the river of Liaohe estuary in different seasons,and calculated the contribution rates of the fates of the pollutants in the river.In all seasons,there was a negative correlation between the pollutants concentration and their migration distance in the river,but the concentration and proportion of different group constituents(saturated hydrocarbons,aromat...
