  • 摘要: 河道内水流和泥沙是污染物迁移转化的主要载体,研究河道内污染物迁移转化过程以及水沙运动对其影响对于治理日益恶化的河流水环境非常重要。结合国内外研究最新动态,对水沙运动作用下污染物迁移转化的试验研究、作用机理、理论模式和数学模型等进行了总结和概述,重点对几种典型的理论模式和数学模型进行了比较分析。目前河流水沙运动对污染物迁移转化效应相关研究存在试验方法比较局限、作用机理存在分歧、理论模式和数学模型不完备等问题,需要进一步进行室内和野外试验技术创新、颗粒界面动力学的微观探索以及污染物在上下覆水和界面上迁移转化理论研究。对河流水沙运动对污染物迁移转化效应研究的研究方向提出了展望。
    Abstract: Flow and sediment are known to be the main carriers of the transport and transformation of pollutants in rivers, and a better understanding of the effect of flow and sediment is therefore of crucial importance for the management of deteriorating water environment. This paper reviews the experimental studies on the effect of flow and sediment on the transport and transformation of pollutants in water, underlying mechanisms, and existing theoretical and mathematical models. In particular, a comparison is made between several models. However, it should be noted that there are some limitations in the experimental methods, the exact mechanism remains controversial, and the theoretical and mathematical models available seem to be not sufficient to characterize the transport-transformation process of pollutants. This underscores the need for further laboratory and field experiments on the interface kinetics of the particles, and theoretical investigation of the transport-transformation process of pollutant in the overlying or underlying water. At last, some directions for further studies are suggested in the study.
