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。
分彆對沉降型憎水有機物自入水點至床麵的吸附沉降過程、汙染物沿床麵的遷移擴展過程、沉底汙染物嚮上覆水體的再懸浮釋放過程、上覆水體中汙染物的遷移（對流擴散、吸附解吸、自淨、揮髮及沉降等）過程等4箇不同階段的汙染物遷移轉化特徵及數學模擬的研究進展進行瞭綜閤評述，可為突髮事故情況下該類汙染物進入地錶水體後水質風險預報提供基礎理論及技術參攷。

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.
