摘要
供排水平衡分析是探究城市供水排水系统运行问题的基础和有效手段。城市供排水平衡受供水管网漏失情况、排水管网收集效率以及排水系统雨污分流情况等因素的影响。湖滨城市由于其特殊的水文地质条件,地下水资源丰富,地下水位较高,地下水渗入排水系统成为城市供排水平衡的重要影响因素。综合考虑各影响因素,提出了适用于湖滨城市的供排水平衡计算公式,并利用该公式以及昆明市主城区2012年的供排水相关数据对昆明市主城区供排水平衡性能进行了评估,计算结果表明,在考虑了各影响因素后,2012年昆明主城区供水-排水-处理量之间基本达到平衡。
The analysis of water supply and drainage balance is a fundamental and efficient method for exploring theoperational status of water supply and drainage system ance of water supply and drainage, such as leakage rate of a city. There are many factors that may impact the bal- of water supply network, collection efficiency of drainage network, and distribution status of rain and sewage. Groundwater infiltration into sewer systems is an important fac- tor that will influence the balance of water supply and drainage. In this paper, based on an overall consideration of possible factors, an equation was proposed to assess the waterfront city. The balance quality of water supply and balance relationship between water supply and drainage in drainage was calculated using the equation based on the water supply and drainage data of Kunming in 2012. The result showed that the water supply and drainage of Kun- ming was in a good balance status by taking above factors into account in 2012.
