基于水量平衡法和夜间最小流量法的供水管网漏损评估

Assessment of water supply network leakage based on water balance and night minimum flow methods

供水管网漏损问题在我国农村地区尤为普遍,不仅造成大量水资源浪费,也带来了极大经济损失。以浙江省永康市一典型农村供水管网为研究对象,基于自上而下年水量平衡分析法和自下而上夜间流量分析法对其漏损进行了分析,根据分析结果对供水管网更新改造提出了合理建议方案。结果表明,基于自上而下的年水量平衡法和夜间最小流量法在农村供水管网漏损评估中表现出了很好的适用性,具有推广示范价值。

Leakage of water supply network is a common problem in China,particularly in rural areas,which results in huge waste of water and great economic losses.Taking a typical rural water supply network in Yongkang City of Zhejiang Province as study object,examinations are made on leakage based on methods of top-down annual water balance analysis and bottom-up night flow analysis,together with reasonable suggestions for rehabilitation and modernization of water supply network based on the results.It shows that both methods have good applicability to leakage assessment and value of promotion and demonstration.
