针对大型城市原水系统中水源众多、规模大、网络结构复杂等特点,考虑水库多输入多输出结构及水质组分之间的相互转化关系,以水质迁移转化基本方程为基础,构建了原水系统水库水质模型,并采用显式差分法推导模型数值解,在保证求解精度的前提下降低了求解的复杂度。将其应用于深圳市原水系统的实例分析表明,模型模拟结果平均误差能满足要求。
In view of the characteristics of many water sources, large scale and complex network structure in large-scale raw water system, considering the relationship between multi-input and multiple-output structure and water quality components in large cities, based on the basic equations of water quality transfer and transformation, Water quality model, and the explicit difference method is used to deduce the numerical solution of the model, which reduces the complexity of the solution under the premise of ensuring the accuracy of the solution. The case analysis of its application to raw water system in Shenzhen shows that the average error of model simulation results can meet the requirements.
