摘　　要：城市污水处理行业作为耗能大户,总碳排放量约占全社会碳排放量的2%。高能耗、高碳排放的传统城市生活污水处理过程与低碳、可持续发展理念背道而驰。总结了城市污水处理厂的碳排放现状,介绍了符合时代发展的城市污水处理新理念,讨论了相关新技术在我国探索性应用的初步成效。重点关注用于城市污水厂减排和资源回收的前沿技术、创新范式和发展趋势,结合实际应用案例阐明城市污水低碳处理和资源回收的可行性与前景。提出了我国城市污水厂在达成减污降碳目标下所需面临的两方面关键挑战,并为污水处理厂的绿色低碳转型提出解决思路。Municipal wastewater treatment plants(MWTPs) consume a large amount of energy,accounting for over 2% of the electrical energy consumption of municipal public utilities.The conventional municipal wastewater treatment processes with high carbon emissions run counter to the development of low-carbon,sustainable water treatment.This study summarized the current situation of carbon emission in MWTPs and introduced new paradigms of water treatment and resource recovery of MWTPs.The key role of innovative modes and state-of-the-art technologies in reducing carbon emissions and increasing energy recovery of MWTPs were discussed.This study clarified the feasibility and prospect of emission reduction and resource recovery of MWTPs by discussing the practical application cases.Two key challenges for Chinese MWTPs to meet the goal of pollution control and carbon reduction were suggested.Correspondingly,solutions for transforming conventional MWTPs into advanced versions with full potential for resource recovery were proposed.
