日本给水管网布局理论与启示

Review of Japanese Theory on Water Distribution System Layout

如何使供水管网具有合理布局,适应城市发展,满足用户需求,减少漏水和节约能耗药耗,是自来水行业面临的重要任务。日本在城市给水管网布局理论方面具有很强的代表性,为此从供水系统组成、配水分区和配水池三方面介绍了日本给水管网布局理论,并简要说明了东京市给水管网的应用状况,最后提出在明确管段功能、管网分层次模拟和充分发挥蓄水设施作用等方面的启示。

How to make water distribution system have rational layout, adapt to urban develop-ment, meet user needs, reduce leakage and save energy and chemical consumption is an important taskfacing the water industry. Japanese theory on water distribution system layout is highly representative.The theory was discussed in terms of system composition, water distribution zoning and storage facilities.Tokyo water distribution system was described as a case study. It is concluded that clear definition of piperole, hierarchical simulation of water distribution system andmakingfull use of storage facilities construc-tion are important for rational layout of water distribution system.
