Research Status and Hotspot Analysis of Biochar Application in Sewage Treatment Which Based on Bibliometric Method
based on the analysis of biblimethod,in China Zhiwang(CNKI)database on the core of biocarbon sewage treatment journal research results for samples,using the Cite Space information measurement and visualization software,analyze the field post,institutions,the author and keywords,discusses and summarize the field research hotspot and development trend.The results show that:(1)the number of biochar in sewage treatment has increased significantly in recent years,and the research has made remarkable progress;(2)the application of biochar in sewage treatment is mainly focused on the adsorption of heavy metals and degraded sulfate in sewage;(3)before 2015,the research on biochar in sewage treatment is very few,mainly focusing on the preparation of biochar.Since 2015,the hot spot has mainly focused on the study of biochar modification and the adsorption of refractory elements in sewage treatment,followed by the search for more environmentally friendly and efficient treatment of sewage materials.
