- 摘要:
- 在雨季面对水环境和水安全双重压力下,如何提升城镇排水系统的可靠性、弹性与可持续性,对保障城镇水系统安全日益重要。城市排水系统具有动态性、多目标性和不确定性特征,从面向流域治理的角度,在进一步削减合流制溢流污染、最大程度地发挥排水系统“源头-过程-末端”能力等多目标协同下,系统的运行控制日益复杂且控制难度日益增大。实时控制技术(RTC)根据实时监测数据动态调整控制策略,对排水管网附属设施及污水处理厂进行干预,以最大程度挖潜和发挥排水设施的调蓄和处理能力,为排水系统运行提供了智能化的解决方案。介绍了实时控制技术的研究历程以及控制工艺和策略、控制模型和控制算法等关键技术的发展,总结了对我国开展实时控制的启示。
- Abstract:
- Under the dual pressure of water environment and water safety in wet weather, how to improve the reliability, flexibility and sustainability of urban drainage system is increasingly important to ensure the safety of urban water system. The urban drainage system has characteristics of dynamic, multi-objective and uncertainty. From the perspective of watershed treatment, under the multi-objective coordination of further reducing the combined system overflow pollution and maximizing the “source-process-end” capacity of drainage system, the operation and control of the system become increasingly complex and difficult. Real time control (RTC) maximizes the storage and treatment capacity of facilities, by dynamically adjusting the control strategy according to the realtime monitoring data, and intervening in the ancillary facilities of drainage system and wastewater treatment plant, in order to provide an intelligent solution for the operation of urban drainage system. Therefore, this paper summarizes the research progress of RTC, the development of control process and strategy, control model and control algorithm, and the inspiration for applying RTC in China.
