摘　　要：对无锡市XZ片区污水系统实施了在线流量监测,详细介绍了监测数据核查修正的过程,分析了污水泵站、系统干管以及典型小区的污水排放规律,以期加深对系统污水管网排水特性的认识,掌握系统的旱天、雨天运行规律。结果表明:XZ片区污水系统存在显著的雨水混接现象;下游基本都处于过载状态,管网负荷偏大且坡度平缓,管网水力状态主要受泵站启闭状态影响,表现出相似的水深-流速变化规律;干管流速不超过0.3 m/s,易发生淤积。监测结果为污水系统的管理和建模提供可靠的数据支撑。An on-line flow monitoring was performed in XZ sewage system of Wuxi City.In order to understand discharge patterns of the system in dry and wet weather conditions,the detailed procedure of amendments and verifications to the monitoring data was introduced and the discharge characteristics of the pumping station,the trunk,and a typical residential system were analyzed.The results showed that,there was a significant phenomenon of illicit connections in XZ sewage system;the network load is so large that downstream pipelines were still surcharged,in addition to the flatness of pipelines′ slope.The hydraulic condition of the sewerage system,showing a similar depth-velocity variation,was affected mainly by the pumping station;the velocity in trunks didn′t exceed 0.3 m/s,where the sediment was easily produced.The monitoring results provided reliable data support for the management and modeling of the sewage system.
