摘要
为深入了解好氧颗粒污泥(aerobic granular sludge,AGS)的研究现状与研究热点,本文基于中国知网(CNKI)数据库和Web of Science核心合集数据库,采用文献计量学方法对2008—2021年间发表的AGS研究文献进行梳理和总结,并结合VOSviewer可视化工具进行关键词共现聚类分析,绘制了展现国内外AGS研究领域知识演化的各类知识图谱。关键词分析表明,AGS在处理不同类型污水的应用、利用AGS多重生物功效(脱氮除磷)以及AGS形成机理条件、强化造粒和连续稳定性培养是AGS的主要研究热点。国内AGS研究呈快速增长趋势,以“AGS形成机理”为主;国外研究热点主要以“AGS启动反应器类型和解体恢复”为脉络。AGS快速造粒与稳定性培养、各类功能性微生物协同方式,以及继续拓宽AGS在不同领域的高效利用可能成为今后的研究热点。
In order to understand the research status and hotspot of aerobic granular sludge(AGS)at home and abroad,bibliometrics was used to review and summarize the global literatures on AGS published between 2008 and 2021 based on the China National Knowledge Network(CNKI)database and the Web of Science core database.At the same time,VosViewer visualization tool was used to conduct keyword co-occurrence cluster analysis,and various knowledge graphs were drawn to show the evolution of knowledge in AGS research field at home and abroad.Key words analysis showed that the application of AGS in the treatment of different types of wastewater,the utilization of AGS multiple biological functions(nitrogen and phosphorus removal),the formation mechanism and conditions of AGS,enhanced granulation and continuous stability cultivation were the main research hotspots of AGS.The research progress of AGS in China has been increasing rapidly,mainly focusing on the formation mechanism of AGS.Overseas research focuses on the types of AGS start-up reactor and disintegration and recovery.The rapid granulation and stable culture of AGS,the synergisation of various functional microorganisms,and the continued expansion of the efficient utilization of AGS in different fields may become the research hotspots in the future.
