To meet the increasingly stringent discharge standards of wastewater treatment plants (WWTPs) in the Taihu Lake Basin, the Chinese government successively established the National Special Water Project Program to develop new technologies to retrofit and upgrade existing wastewater treatment processes during the 11th, 12th, and 13th Five-Year Plans. However, there is a lack of systematic sorting of the existing research outcomes, and thus hinders the application and promotion of the upgrade technologies. Based on the outcomes of the National Special Water Project and a field survey, this research analyzed the current status of wastewater treatment in the Taihu Lake Basin and systematically integrated the retrofitting measures of WWTPs in terms of achieving the Grade IA of the national standard and local stricter discharge standards (DB 32/1072-2018 and DB 33/2169-2018). In particular, the boundary conditions, design parameters, specific recommendations of the technologies, and some typical engineering cases were provided accordingly. Finally, this study discussed the future development directions of WWTPs during the upgrade process from the perspective of carbon neutrality and digitalization. The present work will hopefully assist in retrofitting and constructing WWTPs to achieve the stricter effluent discharge criteria and help optimize the design and construction of WWTPs in the best way.
为满足太湖流域污水处理厂（WWTP）日益严格的排放标准，中国政府在“十一五”、“十二五”和“十三五”期间相继设立了国家水专项，旨在开发新技术，对现有污水处理工艺进行改造升级。然而，目前缺乏对现有研究成果的系统梳理，阻碍了升级技术的应用和推广。本研究基于国家水专项的研究成果和实地调查，分析了太湖流域污水处理的现状，系统地整合了 WWTP 实现国家标准一级 A 和地方更严格排放标准（DB 32/1072-2018 和 DB 33/2169-2018）的改造措施。特别地，提供了相应的边界条件、设计参数、技术的具体建议和一些典型的工程案例。最后，本研究从碳中和和数字化的角度讨论了 WWTP 在升级过程中的未来发展方向。本研究希望能有助于 WWTP 的改造和建设，以达到更严格的排放标准，并有助于优化 WWTP 的设计和建设。
