摘 要
城市排水管网雨污分流改造是解决当前城市水环境问题的重要举措。随着城市化进程的加速，传统合流制排水系统带来的污染问题日益突出，严重影响了水体质量与生态环境健康。为应对这一挑战，本研究以提升城市排水系统的可持续性为目标，系统分析了雨污分流改造的技术路径、经济可行性和实施策略。研究采用实地调研、数值模拟和成本效益分析相结合的方法，选取典型城市区域作为案例，深入探讨了不同改造方案在水质改善、雨水资源化利用及长期经济效益方面的表现。结果表明，基于分区优化的渐进式改造模式能够显著降低初期投资压力，同时实现较好的环境效益。此外，通过引入智能化管理技术，可进一步提高系统的运行效率和适应性。本研究的创新点在于提出了结合地理信息系统的动态评估模型，用于指导复杂条件下雨污分流改造的优先级排序，并首次量化了不同改造策略对碳排放的影响。主要贡献在于为决策者提供了科学依据和技术支持，有助于推动城市排水系统向绿色、低碳方向转型，为实现水环境综合治理目标奠定了基础。

ABSTRACT
The separation transformation of urban drainage networks for stormwater and sewage is a critical measure to address current urban water environment issues. With the acceleration of urbanization, pollution problems caused by traditional combined sewer systems have become increasingly prominent, severely affecting water quality and ecological health. To tackle this challenge, this study aims to enhance the sustainability of urban drainage systems by systematically analyzing the technical pathways, economic feasibility, and implementation strategies of the separation transformation. A combination of field surveys, numerical simulations, and cost-benefit analyses was employed, with typical urban areas selected as case studies to explore the performance of various transformation schemes in terms of water quality improvement, rainwater resource utilization, and long-term economic benefits. The results indicate that a phased transformation model based on zonal optimization can significantly alleviate initial investment pressures while achieving favorable environmental outcomes. Furthermore, the integration of intelligent management technologies can enhance system operational efficiency and adaptability. An innovation of this study lies in the development of a dynamic evaluation model incorporating geographic information systems (GIS) to guide the prioritization of separation transformations under complex conditions. Additionally, this study is the first to quantify the impact of different transformation strategies on carbon emissions. The primary contribution of this research is providing decision-makers with scientific evidence and technical support, facilitating the transition of urban drainage systems toward greener, low-carbon directions and laying a foundation for achieving comprehensive water environment governance ob jectives.
