In the last few decades, anti-negative pressure facility (ANPF) has been emerged as a revolutionary approach for sloving the pollution in the Second Water Supply System (SWSS) in China. This study analyzed implications of the safety in SWSS with ANPF, utilizing the water distribution network hydraulic model. A method of hydraulic simulation and security assessment was presented which was able to reflect the number and location of nodes that can be installed in ANPF. Benchmark results through two instance networks showed that 67% and 89% of nodes in each network did not fit the ANPFs for installation. The simple and pratical algorithm was recommended in the water distribution network design and planing in order to increase the security of SWSS.
在过去几十年中，负压设施（ANPF）已成为解决中国二次供水系统（SWSS）污染问题的一种革命性方法。本研究利用配水管网水力模型分析了负压设施对二次供水系统安全性的影响。提出了一种水力模拟和安全评估方法，该方法能够反映可安装负压设施的节点数量和位置。通过两个实例网络的基准测试结果表明，每个网络中67%和89%的节点不适合安装负压设施。建议在配水管网设计和规划中采用简单实用的算法，以提高二次供水系统的安全性。
