摘    要:本文研究了感潮河网水量水质数学模型——Hwqnow模型。该模型不仅反映了感潮河网的水流、水质复杂多变的特点,而且反映了感潮河网水体受各种因素影响下的水量、水质变化规律,尤其是反映了感潮河网水体分别处于好氧、缺氧、厌氧状态下的各水质组分间相互制约、相互影响的变化规律。模型的参数都是在分析机理的基础上通过实验室和现场实验得到的。在计算方法上采用有限体积法对水质基本方程数值求解,物理概念清晰,通用性强,计算稳定收敛。经实测资料审定和验证,取得良好的结果。该模型已用于为改善上海浦东新区河网水环境而进行的调水方案研究以及浦东新区水利一期工程对改善新区水环境的研究中。

关 键 词:感潮河网  水量水质模型  多参数  有限体积法  好氧、缺氧和厌氧  三氮转化

Abstract:The Hwqnow Model (Hydraulics and Water Quality for a Network of Waterways) has been studied in this paper. The conceptual model reflects the characteristics of the unsteady flow and water quality in many influence factors and the changing law of water quality under aerobic, anoxic and anaerobic conditions. All parameters in the model have been obtained from field observations and experiments. Using finite volume method, the convective-dispersion equation is solved numerically. The model has been calibrated and verified using data observed for the river network of Pudong New Area in Shanghai, the model results best agreed with the observed values. The model has been applied to the scheme of controlling water quantity and water quality in order to improve the water quality of the river network of Pudong New Area, also has been applied to researching the influence of the first water resources engineering on improving the water environment in Pudong New Area.
Keywords:tidal river network  hydraulics and water quality model  finite volume method  multi-parameters  ammonia  nitrite and nitrate nitrogen reaction kinetics  aerobic  anoxic and anaerobic conditions
