- 在地势高差大的山区供水系统运行调控中，为应对管网运行压力不均衡引发的漏损率高的问题，本文以某山地城镇供水系统为研究对象，基于供水管网水力模拟分析，提出多种压力调控策略。首先，针对高地调蓄水池输水管线无中途加压泵站的现状，建立水厂出水压力优化调控模型，提出水厂高压供水时段调整和低位管网设置减压阀的联合调控策略；其次，提出规划中途加压泵站优化方案，通过水厂降压与高地供水干线加压相结合，实现高、低位区域供水的分区压力优化。模拟结果表明，低位区设置减压阀进行局部调压，结合“二次调蓄”优化运行策略，平均出厂水压下降4 m。在实际运行中，低位区增设多处减压阀后，区域漏损率从35%降至27%，节水约70万 m3/a，节能降损成效显著。规划增设高地水池供水干线中途加压泵站方案，平均出厂水压下降20 m。研究表明，水力模型可为供水系统精细化压力管理与漏损控制提供可靠支撑。
- Abstract:
- For the operation and regulation of water distribution systems (WDSs) in mountainous areas with significant elevation variations, the unbalanced pressure often leads to a high level of water leakage and loss. This study proposes multiple pressure regulation strategies for a WDS in mountain area based on hydraulic simulation of the WDS. First, under the current operating condition of the WDS, where the transmission pipeline to the high-elevation tank lacks intermediate booster pump stations, an outlet pressure optimization and control model is established for the water treatment plant with lower elevation. A combined regulation strategy (CRS) is proposed, involving the adjustment of high-pressure supply periods at the plant and the installation of pressure reducing valves (PRVs) in the low-elevation sections of the WDS. Second, for the retrofit plan (FP) of intermediate booster pump stations in the transmission line to the high-elevation tank, a pressure management strategy is achieved by integrating pressure reduction at the water treatment plant with pressure boosting along the transmission line, thereby substantially pressure reduction is achieved across the water supply sections in low-elevation. Simulation results indicate that CRS reduces the average outlet pressure of the water treatment plant by 4 m. In actual operation, the regional leakage rate decreased from 35% to 27%, resulting in an annual water savings of approximately 700 000 m3and demonstrating significant achievements in both energy conservation and leakage reduction. Under the FP scenario, the average outlet pressure of the water treatment plant is further reduced by 20 m. The findings confirm that hydraulic modeling techniques can provide reliable support for refined pressure management and effective leakage control in WDSs.
