| 为探究垃圾渗滤液脱氮技术相关研究领域的研究现状、热点和前沿趋势,本文利用VOSviewer和CiteSpace对Web of Science核心数据库中1994-01-01到2024-07-30的垃圾渗滤液脱氮技术领域已发表的研究成果进行可视化分析。结果表明：(1)从年发文量和累计发文量来看,其总体趋势为稳步上升；发文量最高的学者是北京工业大学彭永臻院士,且发文量最高机构也是北京工业大学；中国在该领域的研究成果位居世界第一,且与世界各国有着密切联系,但文章关注度较低。(2)研究热点为生物脱氮、脱氮微生物和人工湿地方面的研究,其中生物脱氮受关注度更高,特别是硝化、反硝化作用,一直是该领域的研究热点。(3)目前研究的前沿聚焦在部分硝化反硝化、部分硝化-厌氧氨氧化、吸附、提高已有菌群的处理效果以及寻找新的高效菌群的研究。本文为垃圾渗滤液脱氮研究方面提供客观、全面的见解,为后续研究提供参考。 |

| Abstract: |
| In order to explore the research status, hotspots, and frontier trends in denitrification technology for leachate, this paper uses VOSviewer and CiteSpace for visual analysis of research achievements published in the Web of Science core database from January 1st, 1994 to July 30th, 2024. The results show that: (1) From the perspective of annual publication volume and cumulative publication volume, the overall trend is steadily increasing; Academician Yongzhen Peng from Beijing University of Technology has published the highest number of papers in this field, and Beijing University of Technology is also the institution with the highest number of publications; China"s research achievements in this field rank first in the world and have close connections with countries around the world but have relatively low attention. (2) The research hotspots are focused on biological denitrification, microbial denitrification, and artificial wetlands. Among them, biological denitrification receives higher attention levels, especially nitrification-denitrification processes which have been a research hotspot in this field. (3) The current frontier focuses on partial nitrification-denitrification processes,partial nitritation-anammox process,adsorption,improving treatment efficiency using existing bacterial communities,and searching for new efficient bacterial communities. This paper provides objective and comprehensive insights into denitrification research on leachate and serves as a reference for future studies. |
