Visualization And Analysis Of Water Treatment Technology Research Based On Knowledge Mapping For Algal-Bacterial Complex Systems

Bacteria and algae are in a symbiotic and reciprocal relationship.In the field of water treatment algal-bacterial symbiosis can achieve the simultaneous removal of nitrogen,phosphorus and organic matter in a single reactor,and algal-bacterial symbiosis has the advantages of high efficiency,low greenhouse gas emissions and simultaneous biomass resource recovery compared to algae or bacteria alone in treating wastewater.Therefore,in the context of carbon peaking and carbon neutrality,algae-bacteria symbiosis water treatment technology is one of the potential options to achieve efficient wastewater treatment and resource recovery.In recent years,scholars at home and abroad have carried out a lot of research work in the field of algal symbiosis for wastewater treatment,but there is a lack of systematic quantitative analysis of the overall development dynamics in the field of mycorrhizal wastewater treatment research.Scientometric analysis is an interdisciplinary discipline that uses the relevant knowledge and theories of scientometrics to quantitatively analyse knowledge carriers with the help of the quantity of various characteristics of the literature,using research methods such as statistics,mathematics and computer science,mainly presented through mathematical models,knowledge mapping and tables.This study is based on the Web of Science(WOS)database to extract literature data on this topic for quantitative research analysis.In addition to traditional measurement methods,this paper introduces a knowledge graph visualisation tool based on R and JAVA languages to show more intuitively and clearly the chronological distribution of literature,citations,collaboration between countries,institutions,authors and the composition of core journals,and to visualise the content of research hotspots by clustering and multidimensional scale analysis of high-frequency subject terms in paper titles,abstracts and keywords.Finally,the keywords are tested for bursts and trends are analysed in relation to changes in the literature to identify key technologies and emerging applications with potential for future development.The study of this paper can help relevant scholars and experts to recognize the current research status,changes in research hotspots and future development trends in the field of mycorrhizal algae wastewater treatment research in China,provide knowledge navigation for individuals and institutions researching and studying the above research fields,and in turn provide a theoretical basis for promoting further engineering practices of mycorrhizal algae symbiosis system water treatment technology in China.
