摘要:
致病微生物在地表水当中会吸附到泥沙上,进而受泥沙运动的影响。水质模型作为研究污染物迁移转化的重要工具,在研究泥沙对微生物的影响方面受到越来越多的关注。本文针对地表水中致病微生物在泥沙和颗粒物影响下分布的解析解进行研究。得出平衡状态下致病菌泥沙影响沿水深分布的解析解。验证结果表明模型和解析解结果较为一致结果,说明该解析解可以作为模型验证的依据。对水质模型解析解的研究不但可以为模型的验证提供依据,而且对深入理解致病菌在泥沙影响下迁移转化规律有积极的意义。

Abstract: Fate and transport of pathogens are affected by sediment transport processes. Mathematical model is getting more attention to understand the fate and transport of both sediment and contaminants. In this study, analytical solutions of pathogens transport model are studied. Based on equilibrium assumptions, an analytical solution for vertical distribution of pathogens under sediment effects is obtained under equilibrium conditions. The analytical solution was then applied to verify a numerical model. The calculated and analytical solution agreed reasonably well. Not only can the analytical solution be used to verify pathogens fate and transport model, but also advance understanding on fate and transport of pathogens.
