Abstract:

Wastewater treatment plants(WWTPs) are confronted with challenges such as high energy consumption,significant carbon emissions, and resource wastage, which have become major bottlenecks limiting the sustainable development of the industry. The core of green transformation lies in promoting efficient recovery and utilization of resources and energy, as well as exploring innovative low-carbon operational models. This study systematically analyzed the carbon emission characteristics of WWTPs and proposed a multi-dimensional carbon reduction strategy. These strategies included the development of high-efficiency biofilm systems, optimization of operational parameters,selection of low-energy treatment processes, adoption of energy-efficient equipment, implementation of intelligent control systems, and promotion of carbon neutrality measures. Based on these strategies, a technical path was developed that aligned carbon reduction goals with the need for process upgrading. Future research should focus on three main directions: establishing standardized systems for carbon emission accounting and evaluation, promoting large-scale engineering applications of low-carbon technologies such as prtial nitrification/anaerobic ammonium oxidation(PD/Anammox) and anaerobic-oxic-anoxic(AOA) processes, and achieving systematic integration and industrial-scale implementation of resource recovery technologies.

摘要：

污水处理厂（WWTPs）面临高能耗、高碳排放及资源浪费等问题，已成为制约行业可持续发展的关键瓶颈。实现绿色转型的核心在于推动资源与能源的高效回收利用，并探索低碳化运行模式的创新路径。基于此，系统梳理了WWTPs的碳排放特征，提出了多维度的碳减排策略，涵盖构建高效生物膜系统、优化运行参数、选择低能耗处理工艺、引入高效节能设备、实施智能化运行控制以及推进碳中和等综合措施。在此基础上，进一步构建了兼顾碳减排目标与工艺升级需求的技术发展路径。未来研究应着重突破三大方向：建立标准化的碳排放核算与评估体系、推动短程反硝化/厌氧氨氧化（PD/Anammox）与厌氧-好氧-缺氧（AOA）等低碳工艺的规模化工程应用以及实现资源回收技术的系统集成与产业化推广。
