Abstract:

In order to analyze the research progress and dynamics of denitrifying bacteria, we analyzed the research overview and development trend of denitrifying bacteria from 1990 to 2022 based on the core database of Web of Science, using tools such as VOSviewer and Citespace. The field has experienced three processes of origin, exploration and development. There are many countries involved but the cooperation is weak, among which the European countries have stronger regional cooperation and higher quality of publications; although China started late, it has developed rapidly, with a large number of publications but insufficient influence; among the core authors, academician Peng Yongzhen of China has published the most articles; and there is less cooperation and communication among the core authors. The keywords present three types of "tool-object-method", and the current research is mainly concerned with the performance of biological denitrification and dedicated to improving the denitrification efficiency of wastewater. Future research will pay more attention to the deepening and expansion of nitrogen oxide emission, the screening of new denitrifying bacteria, the development and application of denitrifying agents, research on simultaneous nitrification and denitrification, and removal of nitrate nitrogen.

Key words: denitrifying bacteria, nitrate nitrogen, Web of Science, bibliometric, knowledge graphs
