摘要
随着城镇化的推进,城镇人口大幅增加,城镇规模不断扩大,为满足城镇用水需求,城镇供水管网的规模也在日渐扩大,迫切需要一种切实有效的分区优化方法。独立计量区域(district metered area,DMA)的提出对城镇供水管网的管理有着重要的意义。首先对国内外学者在DMA分区优化方面的研究进展进行总结,阐述了DMA分区优化的必要性;然后将DMA分区优化方法按不同分区原则进行表述,对比了不同分区原则下供水管网划分的优缺点;最后根据分区评价指标,分别从供水可靠性、水质可靠性和压力均匀性3个方面进行总结,并展望了DMA分区优化方法在供水管网分析中的研究方向和潜在应用价值。
With the advancement of urbanization,the urban population has increased significantly,and the scale of the urban water supply network has been expanding day by day.In order to meet the urban water demand,there is an urgent need for a practical and effective zoning optimization method for the increasing urban water supply net-work.The proposal of district metered area(DMA)is of great significance to the management of urban water supply network.Firstly,the research progress of domestic and foreign scholars in DMA zoning optimization is summarized to expound the necessity;Then,according to different zoning principles,the DMA zoning optimization method is expressed,and the advantages and disadvantages of water supply network division are compared under different zoning principles;Finally,the three aspects of water supply reliability,water quality reliability and pressure uni-formity are summarized by the zoning evaluation indexes to look forward to the research direction and potential ap-plication value of DMA zoning optimization method in the analysis of water supply network.
