- 摘要:
- 目前，合流制排水体制仍为我国部分城镇排水系统排水体制的重要组成部分。在削减溢流污染提升水环境质量方面，全国各大城市通过新建污水处理厂或末端截流系统等措施，取得较好效果，但仍存在设施联动运行管理相对薄弱、排水系统效能发挥不充分等问题。选择长春市中心城区串湖流域排水系统为研究对象，通过构建排水系统模型，评估不同典型降雨情景下流域厂-池-站-网体系内各排水设施的匹配性，针对现状排水设施联动方式运用实时控制（RTC）策略优化设施控制规则，并结合工程改造方案，可最大程度地发挥排水系统削减合流溢流潜力，为流域内截流式合流制排水系统调度运行优化提供参考。
- Abstract:
- At present, the combined drainage system is still an important component of the drainage system in some urban areas of China. In terms of reducing overflow pollution and improving water environment quality, major cities across the country are committed to adopting measures such as building new sewage treatment plants or terminal pipe interception systems, which have had a positive effect. However, there are still issues such as relatively weak management of facility linkage operation and insufficient effectiveness of drainage systems. This study selects the drainage system of the Chuanhu River basin in the central urban area of Changchun as the research object and constructs a drainage system model. Under different typical rainfall scenarios, the compatibility of various drainage facilities in the research area is evaluated based on the system of sewage treatment plant-sewage treatment tank-sewage pump station-sewage pipeline network in the watershed. Real time control (RTC) strategy is applied to optimize facility control rules based on the current linkage mode of drainage facilities, and combined with the engineering renovation plans, the potential of reducing combined sewer overflow in the drainage system is maximized. This study provides reference for the optimization of the scheduling and operation of interception combined drainage systems in the watershed.
