在欧盟，《水框架指令》（WFD）强制所有地表水保持良好的生态和化学状态。河流（排放）浓度和数量需要符合一定的标准。为了应对这一新的立法，城市水的综合管理是一个重要的问题。实时控制（RTC）是一种可以用来提高系统性能的方法。有人建议，以排放为基础的RTC是帮助满足WFD要求的适当工具。为了设计和调整基于排放的RTC方案，并判断对接收水的整体影响，需要建立城市污水系统的综合数学模型。本文讨论了在创建这种模型时遇到的几个问题和解决方案。利用该集成模型，针对特定的案例研究开发了一种基于排放的控制策略，与不受控制的情况相比，该策略能够改善水质。在最后一部分，测试了该控制策略的鲁棒性，作为性能的重要附加度量。可以得出的结论是，有一些工具可以帮助处理世界粮食计划署的业务后果。
In the European Union, the Water Framework Directive (WFD) enforces a good ecological and chemical status of all surface waters. In-stream (immission) concentrations and populations need to comply with certain standards. In order to deal with this new legislation, integrated urban water management is an important issue. Real-time control (RTC) is one approach that may be used to improve the performance of the system. Immission-based RTC has been suggested as a proper instrument to help fulfilling the WFD requirements. In order to design and tune an immission-based RTC scheme and to judge the overall effect on the receiving water, an integrated mathematical model of the urban wastewater system is necessary. Several problems are encountered when creating such a model and solutions are discussed in this paper. With this integrated model, an immission-based control strategy is developed for a particular case study and is shown to be able to improve the water quality compared to the uncontrolled case. In the final part, the robustness of this control strategy is tested, as an important additional measure of performance. It can be concluded that there are tools available to help dealing with the operational consequences of the WFD.
