基于分布式传感器在线监测数据的排水管网安全运行问题识别与分析

Identification and Analysis of Drainage Network Safety Operation Based on Online Monitoring Data of Distributed Sensor

城市排水管网埋藏于地下,存在混接、错接、渗漏、淤堵、溢流、井盖移位、有毒有害气体聚集等安全运行问题。通过对复杂的排水管网建立一套完整、稳定的安全运行监测系统,依托长期可靠的在线监测数据,可以定量的分析、评估及诊断管网的安全运行问题,有效的识别预警雨污混接、污水溢流、管道淤积、城市内涝和可燃气体聚集爆炸等事故,提高市政排水工作的管理效率,具有一定的实用价值和推广意义。

The urban drainage pipe network is buried in the ground,and there are some problems in safety operation,such as mixed connection,misconnection,leakage,clogging,overflow,manhole cover displacement,accumulation of toxic and harmful gases and so on.Through the establishment of a complete and stable safety operation monitoring system for complex drainage networks,and relying on long-term and reliable online monitoring data,it is possible to quantitatively analyze,evaluate and diagnose the safety operation problems of drainage network,and effectively recognize and early warn the accidents such as rain-sewage mixing,sewage overflow,pipeline siltation,urban waterlogging and combustible gas explosion.It can improve the management efficiency of municipal drainage work,and has certain practical value and promotion significance.
