摘要
对现有的泥沙污染水质模型进行分类,总结了国内外泥沙污染基本问题及泥沙污染水质模型研究的成果,指出模型发展方面应加强泥沙与污染物相互作用机理研究,进一步揭示污染物在水体、悬浮泥沙、底泥之间迁移转化的机理,模型的建立应综合考虑污染物的沉降再悬浮、以及吸附解吸、底泥释放等动态过程。
The water quality problem caused by sediment and sediment movement is getting more and more outstanding. The object of the water quality models for sediment-induced pollution is to study the transportation and transformation of pollutants in water environmental system with sediment taken as the carrier of pollutants. In this paper, the water quality models currently used for sediment-induced pollution were classified, and the foundational problems of sediment-induced pollution at home and abroad and research result about the water quality models were summarized. It was pointed out that, for the development of the water quality models, the interaction between sediment and pollutants should be emphasized for further discovery of the mechanism of transportation and transformation of pollutants among water bodies, suspended sediment, and bed sludge. On the other hand, the dynamic processes of deposition and resuspension, adsorption and desorption, and release to bed sludge of pollutants should be taken into account.
