基于粒子源逆向追踪算法的管网污染源快速定位技术
- Title:
- Rapid Pollution Source Location Technology in Water Distribution System Based on Particle Back-tracking Algorithm
- 摘要:
- 水质安全是供水管理的重中之重。一旦发现管网水质异常，应立即启动相应的污染倒查程序，尽快清理污染源。建立了粒子源逆向追踪算法（PBA），可根据下游水质监控点的水质异常信息进行逆向溯源分析，查找可能的污染源位置。同时根据PBA算法开发了相应的程序，集成到已有的实时水力模型中，并应用到某地市新建管网浊度异常处理过程中，取得了良好的效果。
- Abstract:
- Water quality safety is a top priority in water supply management. Once abnormality of water quality of the pipe network is found, corresponding pollution checking procedure should be started immediately to clean up the pollution sources as soon as possible. In the present work, a particle back-tracking algorithm (PBA) was proposed. It could be used to back track the path of water according to water quality abnormal information of monitoring points downstream, and help finding the possible pollution source location. Meanwhile, a program was developed based on PBA algorithm, and it was integrated into the existing real-time hydraulic model. The program was applied to deal with an abnormal turbidity event in a real-life water distribution system, in which good performance was achieved.
