基于水力模型的J市供水管网区块化方案研究

Distribution Blocking System in J City by Using Hydraulic Model

【目的】推进城镇供水管网漏损控制工作。【方法】利用软件建立J市供水管网水力模型并对进行DBS分区,对每个区块实行压力控制,降低背景漏损。【结果】J市供水管网区块化前后的压力、余氯、水龄结果对比分析后,区块化在均衡管网压力、控制漏损、改善水质方面发挥重要作用。【结论】供水管网区块化方案是可行的。

【Objective】Promote the urban water supply network leakage control work.【Method】We established J city water supply network hydraulic model and DBS zoning by software,and pressure control for each block to reduce the background leakage.【Result】The comparison of the results of pressure,residual chlorine and water age before and after the water supply network in J city had concluded that the block played an important role in balancing the pipe network pressure,controlling leakage and improving water quality.【Conclusion】The plan is feasible and has certain guiding significance for production practice.
