【摘要】 管网在线监测技术作为一种新兴的技术手段，近年来受到了较大的关注。以广东某市市政污水管网和箱涵水质、水量在线监测项目为例，展示了在线监测系统在分析管网运行特征、管网淤堵和箱涵污水汇入情况等方面的应用。实践表明，对城市排水系统开展水质、水量在线监测，有助于快速掌握排水系统的运行规律，有效减少排水系统问题排查的人力投入，精准识别问题管段。项目可为其他城市推广排水系统水质、水量在线监测系统提供经验。更多还原

【Abstract】 On-line monitoring of pipe network system is a new technology,which has attracted great attention in recent years. To present the application of on-line monitoring system in analyzing operational characteristics and clogging mechanism of pipe network,as well as the inflow of sewage in box culvert,a kind of on-line monitoring project in Guangdong related to water quality and quantity of municipal pipeline and box culvert is taken as an example. The practice helps the popularization of on-line monitoring system by discovering the operational mode of drainage system rapidly,reducing relevant human input and identifying problems of pipe networks accurately. This study provides experience for promoting on-line monitoring system of water quality and quantity of drainage system in other cities.更多还原
