Smart regulation technology of rainwater storage pond: efficiency analysis

  • 摘要: 随着北京市海绵城市建设全域化推进,雨水调蓄池在城市雨水管理中得到日益广泛的应用,成为全市最主要的源头设施类型之一.但其具有数量众多、单个设施调蓄容积量小、位置分散的特征,以及存在未实现联动运行、自动化运行能力不足等问题.本文基于海绵设施精细化管控需求,研发以数值模拟、逻辑算法为核心,耦合在线感知、物联设备的雨水调蓄池智慧化调控技术,设计符合实际运行场景的调度策略.研究结果表明,智慧化调控技术应用,实现排水管网峰值削减率达4.5%~100%,片区流量峰值削减率可达11.81%.技术成果有效促进雨水调蓄池效益提升,为源头调蓄设施智慧化运行管理提供新思路.

     

    Abstract: With comprehensive sponge city construction in Beijing, rainwater storage ponds have been increasingly used in urban stormwater management, and has emerged as among the most significant source control facilities. However, these facilities are characterized by a large number, small individual storage capacity, scattered locations, with issues such as lack of coordinated operation and insufficient automation capabilities. To meet the need for refined management and control of sponge facilities, smart regulation technology of rainwater storage ponds has been developed, centered on numerical simulation and logical algorithms, with integrated online sensing and Internet of Things (IoT) devices to design scheduling strategies tailored to actual operational scenarios. Data demonstrate that application of this technology can achieve a peak reduction rate from 4.5%-100% in the drainage network and up to 11.81% in sub-catchment flow, to effectively enhance performance of rainwater storage ponds, and provide new approach for intelligent operation and management of source control facilities.
