摘要:
活性污泥法是目前使用最广泛和最经济的污水处理工艺，但是传统脱氮除磷工艺中存在碳源竞争、污泥龄矛盾、污泥沉降性能不佳、占地面积大和处理效能低等问题。基于厌氧/好氧/缺氧运行模式的好氧颗粒污泥（AOA-AGS）技术，通过高效利用污水中的有机物实现内碳源脱氮除磷，是一种极具潜力的污水深度处理新技术。简要论述了AOA和AGS的技术特点，并探讨了二者基于“丰盛-饥饿”假说和厌氧内碳源储存结合的理论基础及优势，总结了AOA-AGS中关键功能微生物种群及其相对含量，重点综述了氧气供给、周期时间设置及碳源等因素对系统处理效能的影响，提出了该技术目前尚存的问题及未来的主要研究方向。
Abstract:
Activated sludge is the most widely utilized approach for cost-efficient wastewater treatment at present. However, There are some problems in the traditional nitrogen and phosphorus removal process, such as competition for carbon sources, contradictions in sludge retention time, poor settle ability of activated sludge, huge land occupation and low operational efficiency. The anaerobic/oxic/anoxic-aerobic granular sludge (AOA-AGS) is a promising technology for wastewater treatment, effectively utilizing carbon sources within the wastewater for endogenous nitrogen and phosphorus removal. This paper discussed the distinct characteristics of AOA and AGS technologies, exploring their synergistic foundation and advantages through the “feast-famine theory” and anaerobic endogenous carbon sources transformation. It summarized the structures and abundances of functional groups within AOA-AGS, and reviewed the effects of key operational factors, such as oxygen supply, time configuration, and carbon sources on treatment performances. Finally, it proposed the remained concerns and future directions of this promising technology.
