- Abstract:
- There are five sewage drainage trunk lines in downtown Shanghai, namely the west trunk line, the south trunk line, the phase Ⅰ combined sewage line, the phase Ⅱ sewage line, and the phase Ⅲ sewage line. The total sewage transportation accounts for approximately 60% of the total sewage treatment capacity of the city. These trunk lines have played a central role in sewage treatment of downtown Shanghai. However, these drainage lines are relatively independent, and there are problems such as unable to stop sewage transportation for maintenance, unable to achieve unified operation and scheduling, and poor capacity to accept additional incremental sewage. Therefore, a hydraulic model of the sewage trunk lines in downtown Shanghai was established by InfoWorks ICM to simulate the operation of the drainage system in dry and typical rainy days. The weak pipe sections in the drainage trunk lines were analyzed, and connecting pipes at sensitive points were installed to achieve peak shifting and allocate sewage flow. Three connecting pipes in the upstream, middle and downstream of the drainage trunk lines can basically complement the trans-regional dispatching capacity, make full use of the pipeline redundancy, and improve the transportation safety of the drainage system.
