基于知识图谱分析的沼渣好氧堆肥研究现状与趋势研究OA

Biogas residue is one of the primary products of anaerobic digestion of organic waste.The economic value and environmental safety of final products can be enhanced through further processing of biogas residue via aerobic composting.Employing a literature analysis methodology,this study synthesizes academic insights from the Web of Science Core Collec-tion database to map the research trajectory of biogas residue valorization via aerobic composting.The findings reveal that:1)Research output in biogas residue aerobic composting demonstrates a consistent upward trajectory.Publications are pre-dominantly concentrated in Environmental Sciences,Environmental Engineering,and Energy Fuels.The foremost contribu-ting nations include China,Italy,and the United States,while leading institutions such as China Agricultural University,Chinese Academy of Sciences,and the Ministry of Agriculture and Rural Affairs of China exhibit both high productivity and robust collaborative networks.2)Current research primarily revolves around the generation and treatment of biogas residue,with a focus on the correlation and coupling between anaerobic digestion and aerobic composting,their environmental im-pacts,system optimization and control,and the enhancement of anaerobic biogas production efficiency.3)Aerobic com-posting of biogas residue enables the deep integration of anaerobic and aerobic treatment processes for organic waste,ser-ving as a critical solution to addressing the sustainable supply of renewable energy and green agricultural inputs.Concur-rently,the identification and mitigation of environmental risk factors such as heavy metals,antibiotic resistance genes(ARGs),and pathogenic microorganisms and the implementation of classified optimization and synergistic treatment tailored to the distinct characteristics of multi-source organic waste are increasingly emerging as key research priorities in the field.
