摘　　要：为梳理污水脱氮领域的研究历程现状、热点和未来研究趋势,采用文献计量学的方法以Web of Science核心合集数据库和中国知网核心期刊数据库为数据源,利用CiteSpace等软件对2000年~2022年WoS文献总体分析,2018年~2022年WoS和CNKI文献对比分析。结果表明:污水脱氮在国际上重视度不断提升;学科主题最具有研究价值的是生物技术、微生物学和能源燃料;领域的研究主要围绕人工湿地、厌氧氨氧化、SBR、吸附和有机碳5大方向。近5年研究以城市污水和生活污水为主体,以活性污泥和人工湿地为主要技术,以基于SBR的MBBR为主要工艺,主要研究微生物机理、降低能耗、重金属和抗生素等特殊污染物的去除。研究热点国际上一方面是新生物脱氮技术的开发,另一方面是降低能耗和增加电能生物质能等能源的产出。国内一方面是对MBR工艺新型填料和新型微生物挂膜的研究,另一方面是新颗粒污泥的开发。在高效脱氮基础上进一步降低能耗和实现高产能将是污水领域未来的研究趋势。In order to review the research history,current situation,hot spots and future research trends in the field of wastewater nitrogen removal,the paper adopts the bibliometrics method and the Web of Science core collection database and the CNKI core journal database as data sources,and uses CiteSpace and other software to make an overall analysis of WoS literature from 2000 to 2022 and a comparative analysis of WoS and CNKI literature from 2018 to 2022.The results show that:The international attention on wastewater nitrogen removal is increasing;China,European and American countries pay more attention to it;The most valuable research topics are biotechnology,microbiology and energy fuels;The research in this field mainly focuses on constructed wetlands,anaerobic ammonia oxidation,SBR,adsorption and organic carbon;In the past 5 years,the research field mainly focuses on urban sewage and domestic sewage,activated sludge and constructed wetland as the main technology,and SBR-based MBBR as the main process,mainly studying microbial mechanism,reducing energy consumption,and removing special pollutants such as heavy metals and antibiotics;The international research focus is on the development of new biological nitrogen removal technology on the one hand,and on the other hand,the research on reducing energy consumption and increasing energy output such as electricity biomass energy.In China,on the one hand,it is the research of new fillers and new microbial membrane is formed in membrane biotechnology,and on the other hand,it is the development of new granular sludge;On the basis of efficient nitrogen removal,further reducing energy consumption and achieving high production capacity will be the future research trend in the field of wastewater.
