东北某市供水管网改扩建模型研究

RESEARCH ON MODELING OF REHABILITATION OF URBAN WATER SUPPLY NETWORK IN NORTHEAST CHINA

供水管网改扩建模型及工况分析能够为目前广泛存在的供水管网老化、漏损率高、多水源切换、局部负荷高、供水安全性差等问题的解决提供有效办法。合理的优化能够降低投资、减少能耗、提高管网运行可靠性。现有的城市供水管网在水源切换,居民生活、工业生产用水量需求增加现实背景下,亟需通过供水管网改扩建来增加供水能力。开发一种优化设计技术,对城市供水管网设计技术进行研究,对城市供水管网建模技术的深入研究,将对改扩建的集约经济起到关键的推动作用。

Analysis on the modeling and conditions of rehabilitation of urban water supply network could give a effective way to solve the issues in the existing network such as pipe ageing, high leakage rate, multiple source switching, low pressure of water supply in local area, and poor safety of water supply. Rational optimize can reduce the investment , energy consumptionand improve the reliability of the network. With the water demand of resident and industry, current network need to improve the capacity of water supplyment through the rehabilitation of network. So the developing optimized design and modeling technique for reseach on the urban network designing and could play a key promotional role for intensive economy of rehabilittion.
