新型供水模式探讨

分析了我国供水系统现状及其存在的问题,提出了适应我国国情的供水管网分区新模式,详细阐述了管网分区方法,包括建立管网微观模型、设定分区阶层、确定区域规模、设置区域边界和进水点、区域规整以及分区方案评估等.分区供水模式可有效解决我国供水系统管理难、调度难、漏失大和产销差异大等问题,适应我国供水系统安全高效经济运行的要求.

New way of water supply

By analysing the present status of water supply and its deficiencies,micro-modeling of water net- work systems,the way of pressure management area suitable in China is put forward,and the way of blocking is detailed,including building the microscopic model of water network systems,determining the number of layers,designing the entrance of area and the size of area,demarcating the borderline of areas,settling areas and evaluating the scenario of blocking areas.The way of blocking can be used to resolve existing problems, such as difficult management,difficult scheduleing,severe leakage and great difference between production and sale,and keep the operation of water supply systems safe and efficient.
