【摘要】：为了分析大范围的压力调控对降低供水管网的漏损水量及生产运行成本的影响,以大规模真实供水管网为例,首先对历年缺水缺压投诉地区的供水情况、用水特点进行详细摸查和分析,选择条件成熟的区域作为压力优化的目标区域,在有针对性地投入资金完善该区域的二次加压设施后,采取分时段隔日深夜逐步降低压力的方式进行大范围调控,不仅大范围降低了供水管网压力,对降低供水管网的漏损水量和生产运行成本也具有明显的效果。
[Abstract]:In order to analyze the influence of pressure regulation on reducing the leakage and production cost of water supply network, taking large-scale real water supply network as an example, the water supply situation in the area of water shortage and pressure deficiency complaints over the years is first analyzed. The characteristics of water use are investigated and analyzed in detail, and the area with mature conditions is selected as the target area of pressure optimization, after the targeted investment to perfect the secondary pressure facilities in the area. Adopting the method of reducing pressure step by step every other night in different periods not only reduces the pressure of water supply network on a large scale but also has obvious effect on reducing the leakage of water supply network and the cost of production and operation.
