摘　　要：上海市中心城区共有5条污水外排干线,分别为西干线、南干线、合流一期总管、污水二期总管、污水三期总管,污水输送总量约占全市污水处理总量的60%,在上海市中心城区污水治理中发挥了核心作用。但是,这些排水干线之间相对独立,并且存在无法停水检修、无法实现统一运行调度、接纳额外的增量污水能力较差等问题。为此,利用InfoWorks ICM建立了上海市中心城区污水干线水力模型,模拟在旱天和典型雨天工况下排水系统的运行情况,分析排水干线上存在的薄弱管段,并在敏感点建立连通管,起到错峰和调配水量的作用。结果表明,在排水干线的上游、中游和下游设置三处连通管基本上能互补跨区域调度能力,充分利用管道余量,提高排水系统的输送安全性。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.
