基于文献计量分析的地下水中氨氮污染去除研究

Research on Removal of Ammonia Nitrogen Pollution from Groundwater Based on Bibliometric Analysis

本文利用CiteSpace和VOSviewer文献可视化软件,分析了Web of Science数据库和CNKI数据库中已发表地下水中氨氮去除相关文献的发文数量、发文国家及机构、发文作者、载文期刊、关键词和共被引情况,研究了30 a来地下水中氨氮污染去除的研究热点与发展趋势。结果表明:2000年之后,地下水氨氮污染去除研究的发文数量不断增长,中美两国在该领域的发文更多、联系更为紧密,近年来在相关政策的推动下,我国在该领域的研究成果明显增多;中国地质大学是发文量最多的机构。目前研究热点集中在材料吸附、厌氧氨氧化、硝化反硝化作用等去除方式,研究的污染介质较多关注浅层含水层、潜流带的地下水,未来应加强新型吸附材料筛选及微生物脱氮等技术的研发。

In this study, CiteSpace and VOSviewer softwares were used to analyze the publications on the subject of ammonium removal from groundwater based on Web of Science(WoS) database and CNKI database, to explore the status quo and future research perspective in the past three decades. The bibliometric analysis results showed that the number of published papers has continued to increase since 2000, and China and USA have published more papers on the subject. China University of Geosciences was the institution with the largest number of published papers. At present, research focused on the removal methods,including adsorption, anammox, and nitrification/denitrification. The relevant research on the ammonium in groundwater mainly targeted those in shallow aquifers and hyporheic zones. In the future, more efforts should be made to develop new adsorbent and bioremediation technologies such as nitrification/denitrification processes.
