摘要
突发事件泄漏的石油类污染物在水体中的迁移转化规律一直是环境水力学研究的难点。根据石油类污染物的物理、化学特征,针对其在水体中不同阶段的运动动力学特征,分别从油膜在水体表层的扩展迁移过程、水体表层油膜的风化过程、油膜污染物向下层水体的扩散过程、水体中石油类污染物的迁移转化过程、石油类污染物的迁移转化过程物理试验、常用溢油模型6个方面归纳分析了国内外在动力学机制及数学模拟方面的研究进展,并分析了未来研究趋势。
The migration and transformation law of oil pollution in the sudden pollution accidents has always been a key problem in the field of environmental hydraulics.According to the physical and chemical characteristics of this pollutants,the research progress in dynamic mechanism and mathematical simulation at home and abroad is summarized from six aspects,namely,the spreading and migration process of oil slick in water surface,the weathering process of oil slick in water surface,the diffusion process of oil slick into the deep water,the migration and transformation process of oil pollutants in water,physical test for migration and transformation of oil pollutants,the common oil spill models according to the kinetic characteristics of oil pollutants at different stages in water,and the future research trend is analyzed.
