辽河河口区河流中石油类污染物归宿
Fates of petroleum pollutants in the river of Liaohe estuary.
摘要
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, aromatic hydrocarbons, and polar hydrocarbons) varied significantly with seasons. In winter, sedimentation and transportation were the major fates of the pollutants, accounting for 39. 5% and 60. 5% , respectively. Taking the sedimentation in winter as the reference, the contribution rates of sedimentation, degradation, and transportation of the pollutants in the river in summer were 39. 5% , 42.4% , and 18. 1% , respectively, and the contribution rates of the fates of the group constituents differed markedly.关键词
