基于水力模型的供水管网分区管理在北方某市的应用

以实现某市供水管网分区管理为目标,在管网水力模型的基础上,根据北方城市供水系统的特定要求,将网络社区划分算法与管网分区管理理念相结合进行分区。结果表明:分区后东一区和西二区的管网压力有所上升,其他四个子区域压力呈现下降趋势,城市管网供水压力得以均衡。拓扑算法分区与理论分区相结合的管理方案能够有效降低管网漏失水量,提高供水安全可靠性。西二区一级水质百分比上升59.13%,其他区域水质发生不同程度变化,优质水百分比上升,水在管网中的停留时间得到有效缩短。管网分区后可为水务公司带来114.038万元的年收益。研究成果对改善供水管网管理及提高水务公司运行效率具有参考价值。

Application of Water Supply Network Distribution Management Based on Hydraulic Model in a City in the North

In order to achieve water distribution system zonal management in a city, based on the hydraulic model of pipe network, according to the specific requirements of the northern city water supply system, combining the network community partition algorithm with the pipe network partition management concept to partition. The results show: After the partition, the pressure of the pipe network in the Dong yi and Xi er districts increased, and the pressure in the other four sub-regions showed a downward trend, water supply pressure in urban pipe network can be balanced, the management scheme of the combination of topological algorithm partition and theoretical partition can effectively reduce the loss of pipe network, improve water supply safety and reliability; the water quality percentage of the first grade of the Xi er zone increased by 59.13%, and other areas of water quality changes in varying degrees, the percentage of premium water is rising, the residence time of the water in the pipe network is effectively shortened; after the pipe network partitions can bring annual revenue 1,140,380 yuan for water companies. The research results are of reference value to improve the management of water supply pipe network and improve the operation efficiency of water company.
