多水源管网供水方式研究

Research of Water Supply Way with Multi-Water-Sources Water Supply Network

目的为了保证城市供水的可靠性,满足用户对用水量的需求.方法对城市多水源给水系统的配水实行分时分级供水方式并对此理论进行分析,建立分时分级方程.结果得出满足用户逐时用水量变化的多水源管网供水方式,使水量调节从静态变为动态.结论分时分级供水是城市多水源给水管网供水的一种有效方式,适应了城市用水量的逐时变化,使泵站和管网设计、运行更合理.

To guarantee the reliability of the urban water supply, and satisfy the demand for water, some urban water supply systems with multiple water sources implement classification and time sharing water supply way. The article analyzes this manner theoretically, and sets up an equation for the classification and time sharing supply way, obtains a water supply form which can meet the hourly changing water consumption of urban water users. Classification and time sharing water supply way is an effective way to urban water supply networks with multiple water sources, can adapt the hourly change of water consumption and make the pumping station and network design or operation more reasonable.
