摘要

摘要

En 中文
为缓解溢流污染对生态系统的影响,提出了一种用于集成城市排水系统(UDSs)的多目标优化(MOP)控制方法。现有研究通常针对单一降雨事件、单一目标或孤立设施,缺乏全面、长期的策略。为解决这一问题,所提出的方法纳入长期降雨数据,以优化UDSs中关键系统组件(包括排水管道、泵站、滞留管道、智能调蓄井(IDWs)和污水处理厂(STPs))的性能。该MOP方法动态协调基础设施,以减少合流制污水溢流(CSOs)和污染物负荷,同时平衡运营成本和设施性能。在中国杭州余杭区的一项案例研究中,在六个月降雨序列下,该方法在中雨条件下实现了平均47.87%的CSOs削减率,在暴雨条件下实现了33.60%的削减率,相应的污染物排放削减率为77.55%和71.37%。优化还提高了泵站效率,运营时间减少了13.76%。识别出影响系统性能的关键IDWs,其中IDWs 9、10和14最为关键。这些结果表明,该方法能够显著改善UDSs的长期水力与环境性能,为可持续城市水资源管理提供理论见解和实践指导。
