摘要
排水系统实际运行中水力条件多变,排水管道很难在设计的恒定流条件下运行,导致管道携带的可沉积物周期性地沉降、冲刷、再悬浮、输移。管道沉积物造成管道过水能力降低,在降雨周期性的变化和其中生物化学作用下,改变了所输送污染物的时空分布,对污水处理厂和受纳水体均造成影响甚至冲击。管道沉积物管理是智慧排水系统的重要应用场景,对以排水沉积物管理为核心的智慧排水系统的架构和关键技术做了分析。
Due to the variable hydraulic conditions in the real drainage system,it is almost difficult for the sewer system to operate under the designed"steady flow"condition,which causes the sedimentable materials carried by the sewer water to periodically settle,erode,resuspend,and transport.Sewer sediments reduce the capacity of the sewers.Especially the cyclical hydraulic changes in rainfall and the biochemical processes in the sewer change the temporal and spatial dis-tribution of the pollutants transported,which will affect or acutely impact on both the WWTP and the receiving water.Sewer sediment management should be an important application scenario for smart drainage systems.Research presented has analyzed the framework and key technologies of the smart drainage system with drainage sediment management as the core.
