摘要：The objectives of this study were to analyze the research trends and research hotspots of biogas slurry utilization and treatment in the past 20 years (1996-2018) by literature metrology. In the early 21st century, relevant research has increased rapidly. A total of 175 SCI papers with biogas slurry as the keyword were retrieved on the Web of Science. Keywords co-occurrence graphs showed the biogas slurry, growth, yield and nitrogen were the core keywords. The top four journals in the number of articles are Bioresource Technology, Pakistan Journal of Botany, Applied Soil Ecology, Environmental Science and Pollution. The top three cited authors with high central node are Ryckebosch E, Serejo ML, Abdeen Frh. The top four countries with the number of published articles are China, India, Pakistan and Germany. In conclusion, the core development direction of this field is "biogas slaque-quality", and subordinate line is "biogas slurry, waste water treatment, nutrient removal and activated sludge".
