Research on water supply and drainage system renovation strategies in comprehensive urban water environment management
城市水环境综合治理中给排水系统改造策略研究

摘要

城市水环境质量和给排水系统运行能力之间存在着紧密的联系。在城市规模不断扩大、建设强度逐步提高的过程中，部分区域出现了诸如雨污混接、管网老化、排水能力欠缺、污水收集率不高、内涝风险加剧等一系列问题，这些问题对河湖水质、城市的安全运行产生了影响。给排水系统改造是城市水环境综合治理的关键基础性内容，需要从管网普查、雨污分流、污水提质增效、海绵城市建设、泵站调度、智慧监测等多个方面共同推进。本文针对城市水环境治理里给排水系统存在的问题、改造策略进行分析，目的是为城市水环境质量的提高给予一定的参考。

Abstract

There is a close relationship between urban water environment quality and the operational capacity of water supply and drainage systems. With the continuous expansion of urban scale and the gradual increase in construction intensity, some areas have encountered a series of problems such as combined sewer overflows, aging pipe networks, insufficient drainage capacity, low sewage collection rates, and increased risk of urban flooding. These problems have impacted river and lake water quality and the safe operation of cities. Water supply and drainage system renovation is a key foundational component of comprehensive urban water environment management, requiring joint efforts from multiple aspects including pipe network surveys, rainwater and sewage separation, sewage quality improvement and efficiency enhancement, sponge city construction, pump station scheduling, and intelligent monitoring. This paper analyzes the problems and renovation strategies of water supply and drainage systems in urban water environment management, aiming to provide a reference for improving urban water environment quality.
