摘　　要：为了促进污水处理厂(WWTPs)的低碳可持续运营管理,近年来致力于改善出水质量、削减运营成本和降低温室气体排放的智能曝气控制技术蓬勃发展,但关于可持续污水处理厂的最佳曝气控制策略尚未达成共识。系统综述了曝气过程中溶解氧浓度对于N2O释放的影响,通过分析对比不同曝气控制策略的差异及优缺点,提出曝气控制策略进一步优化的建议,为实现市政污水处理厂溶解氧的综合科学管理提供理论支撑,旨在为污水处理行业提供科学依据和技术支持,促进环境保护和可持续发展。在曝气控制系统中加入N2O排放量化模型来实现出水水质、曝气能耗、温室气体排放三者之间的平衡是未来的关键研究方向,需开发更准确、更合适的温室气体量化模型、灵活的控制方法和智能曝气策略,以满足污水处理厂更多的需求。In order to promote low-carbon and sustainable operation and management of wastewater treatment plants(WWTPs),intelligent aeration control technologies have flourished in recent years,which are committed to improving effluent quality,reducing operating costs,and reducing greenhouse gas emissions.However,there is no consensus on the optimal aeration control strategy for sustainable wastewater treatment plants.A systematic review was conducted on the impact of dissolved oxygen concentration on N2O release during the aeration process.By analyzing and comparing the similarities,differences,advantages and disadvantages of different aeration control strategies,suggestions were proposed for optimizing future aeration control.This provides support for the comprehensive scientific management of dissolved oxygen in sewage treatment plants,aiming to provide scientific basis and technical support for the sewage treatment industry,promote environmental protection and sustainable development.Adding a N2O emission quantification model to the aeration control system to achieve a balance between effluent quality,aeration energy consumption,and greenhouse gas emissions is a key research direction in the future.It is necessary to develop more accurate and suitable greenhouse gas quantification models,flexible control methods,and intelligent aeration strategies to meet the more needs of sewage treatment plants.
