In recent years numerical modelling has become a standard procedure to optimise urban wastewater systems design and operation. Since the models were developed for the subsystems independently, they did not support an integrated view to the operation of the sewer system, the wastewater treatment plant (WWTP) and the receiving water. After pointing out the benefits of an integrated approach and the possible synergy effects that may arise from analysing the interactions across the interfaces, three examples of modelling case studies carried out in Germany are introduced. With these examples we intend to demonstrate the potential of integrated models, though their development cannot be considered completed. They are set up with different combinations of self-developed and commercially available software. The aim is to analyse fluxes through the total wastewater system or to integrate pollution-based control in the upstream direction, that is e.g. managing the combined water retention tanks as a function of state variables in the WWTP or the receiving water. Furthermore the interface between the sewer and the WWTP can be optimised by predictive simulations such that the combined water flow can be maximised according to the time- and dynamics-dependent state of the treatment processes.
近年来，数值模拟已成为优化城市污水系统设计与运行的标准程序。由于这些模型是针对子系统独立开发的，它们并不支持对下水道系统、污水处理厂（WWTP）和受纳水体的运行进行综合考量。在指出综合方法的益处以及分析跨界面相互作用可能产生的协同效应之后，介绍了在德国开展的三个建模案例研究实例。通过这些实例，我们旨在展示综合模型的潜力，尽管其开发工作尚未完成。它们是使用自行开发的软件和商业软件的不同组合建立的。目的是分析通过整个污水系统的通量，或者在上游方向整合基于污染的控制，例如根据污水处理厂或受纳水体中的状态变量来管理组合式蓄水池。此外，下水道与污水处理厂之间的界面可以通过预测模拟进行优化，以便根据处理过程的时间和动态状态使组合水流最大化。
