摘要：为量化市政污水处理厂扩建工程的环境效益与绿色低碳转型价值，以天津市东丽区张贵庄污水处理厂二期工程为研究对象，基于其“TOT+BOT”复合模式建设背景与2024 年正式投运后的运行数据，系统分析了二期工程的工艺优化特征、污染物去除效能及资源循环水平，并重点评估了其对区域水环境、生态系统及绿色发展的综合改善效应。研究结果表明：二期工程创新集成“五段式巴登甫工艺+MBR 膜分离技术”，配套全国首个精确曝气系统与6 兆瓦光伏项目，投运后全厂污水日处理能力提升至45 万吨，污泥日处理能力达600 吨，出水水质稳定优于《城镇污水处理厂污染物排放标准》（DB12/599-2015）A 标准，总氮去除效率达90%-95%，核心污染物年削减量较一期工程提升125%。二期工程光伏项目运营期内预计减排二氧化碳10.1 万吨，助力该厂于2025 年入选全国首批“污水处理绿色低碳标杆厂”。作为京津冀协同发展重点项目，二期工程的投运显著改善了东减河、北塘排水河及渤海大沽口近海水环境质量，提升了区域防洪排涝与生态修复能力，构建了“高效治污—资源循环—低碳运行”的市政污水处理新模式。

Abstract: To quantify the environmental benefits and green low-carbon transformation value of the expansion project of municipal sewage treatment plants, this study takes the Phase II Project of Zhangguizhuang Sewage Treatment Plant in Dongli District, Tianjin as the research object. Based on its construction background of the composite "TOT+BOT" model and the operation data after its official commissioning in 2024, it systematically analyzes the process optimization characteristics, pollutant removal efficiency and resource recycling level of the Phase II Project, and focuses on evaluating its comprehensive improvement effects on the regional water environment, ecosystem and green development. The results show that the Phase II Project innovatively integrates the "five-stage Bardenpho process + MBR membrane separation technology", supported by the nation's first precise aeration system and a 6-megawatt photovoltaic project. After commissioning, the daily sewage treatment capacity of the whole plant has been increased to 450,000 tons, and the daily sludge treatment capacity has reached 600 tons. The effluent quality is stably better than the Class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (DB12/599-2015), with the total nitrogen removal efficiency reaching 90%-95%, and the annual reduction of core pollutants increased by 125% compared with the Phase I Project. The photovoltaic project of the Phase II Project is expected to reduce carbon dioxide emissions by 101,000 tons during the operation period, helping the plant be selected as one of the first batch of "Green and Low-Carbon Benchmark Sewage Treatment Plants" in China in 2025. As a key project for the coordinated development of the Beijing-Tianjin-Hebei region, the commissioning of the Phase II Project has significantly improved the water environment quality of the Dongjian River, Beitang Drainage River and the coastal waters of Dagu Estuary in the Bohai Sea, enhanced the regional flood control, drainage and ecological restoration capabilities, and constructed a new municipal sewage treatment model of "efficient pollution control - resource recycling - low-carbon operation".
