【摘要】 为了解决北方某市供水管网水厂出水压力不足、部分路段供水管网压力波动大、区域压力不均衡等问题,基于该市供水管网水力模型,综合考虑该市供水管网压力、水量、地形、行政管理区域等相关因素,对该市供水管网进行DBS分区。结果表明,该市管网实施分区管理后,A水厂供水负荷减小,用水高峰期出水压力不足问题得到解决;部分路段水压过高问题得到解决;各区块供水管网压力得到均衡。因此,DBS区块化管理在该市取得较明显效果,对改善供水管网管理水平具有一定的参考价值。更多还原

【Abstract】 In order to solve the problem of insufficient water pressure in the water supply network of a city in the north,large fluctuations in the pressure of the water supply pipe network in some sections,and uneven regional pressure,based on the hydraulic model of the city’s water supply network,the city’s water supply network is DBS partitioned by considering the pressure,water volume,topography,administrative area and other relevant factors of the city’s water supply network.The results show that after the implementation of the district management of the city’s pipe network,the water supply load of the A water plant is reduced,and the problem of insufficient water pressure during the peak water supply period is solved;The problem of excessive water pressure in some sections is solved;The pressure of the water supply network in each block is balanced.Therefore,the DBS block management has achieved significant results in the city and has reference value for improving the management level of water supply network.更多还原
