备用水源地水量与城市需水量平衡分析

Balanced Analysis of Water Quantity between Backup Water Source and Urban Demand

随着水资源的日益短缺和突发性水污染事故的频繁发生,在各大中型城市建设备用水源地,对保障城市饮用水安全和城市的建设发展具有重要的作用。本文将备用水源地分为发展预留水源地和应急水源地,探讨了备用水源地分别作为预留发展水源地、应急水源地、预留发展和应急同时兼顾水源地时对城市水量的要求以及与城市需水量间的平衡关系,并对城市生活需水量和工业需水量计算模型进行了修正;同时,将上述理论应用于扬州市区,通过城市需水量计算来论证备用水源地水量要求,并验证了拟将夹江河段作为扬州市备用水源地的可行性。该研究结果可为备用水源地的选址提供理论依据。

With the increasing shortage of water resources and the frequent occurrence of sudden water pollution accidents,the constructions of the backup water source in the large and medium-sized cities have played an important role in protecting the drinking water safety and urban construction. This paper divides backup water source into development reserve water source and emergency water source, discusses the requirements of backup water source when it is used as development reserve water source,emergency water source and the combination of both development reserve water source and emergency water source, and also the balance between these requirements and urban water demand, and fixes the urban life water demand calculation model and industrial water demand calculation model. In the meantime, the theory is applied to Yangzhou City. Through the urban water demand calculation, the paper demonstrates the water requirements of backup water source and validates the feasibility of taking Jiajiang River as the backup water source for Yangzhou City. The study result can provide the theoretical basis for selecting the location of backup water source.
