摘要
分别对沉降型憎水有机物自入水点至床面的吸附沉降过程、污染物沿床面的迁移扩展过程、沉底污染物向上覆水体的再悬浮释放过程、上覆水体中污染物的迁移(对流扩散、吸附-解吸、自净、挥发及沉降等)过程等4个不同阶段的污染物迁移转化特征及数学模拟的研究进展进行了综合评述,可为突发事故情况下该类污染物进入地表水体后水质风险预报提供基础理论及技术参考。
A comprehensive review was made respectively to the research progress of pollutant migration characteristics and mathematical simulation in the following four different stages： the adsorption and settlement process from the entry point to the bed surface of sedimentation hydrophobic organic compounds, the migration and extension process of pollutants along the bed surface, the precipitation pollutants’ resuspension and release process to overlying water, the migration process of pollutants in overlying water including convective diffusion, adsorption-desorption, self-purification, volatilization and settlement.The purpose of this study is to provide the basic theory and technological references for water quality risk prediction after such kind of pollutants enter the surface water in accident cases.
