摘要
为探究市政污泥资源化处理领域研究进展,筛选了WOS数据库2008—2024年700余篇期刊论文进行可视化分析。利用CiteSpace等可视化软件绘制了发文量、国家合作、机构合作、关键词突现等科学知识图谱。研究结果表明:该领域的研究呈阶梯式稳步增长态势,演进轨迹与政策导向紧密关联;中国、美国等核心国家为该领域成果输出大国,以中国科学院为首的机构同其他国家主要研究机构形成密集合作网络;环境科学为发文量最多的学科领域。当前研究热点聚焦四大主要技术路径:通过生物转化实现土壤改良功能重构的生态化利用、针对氮磷等营养元素的定向提取与高值转化、制备环保材料、基于热转化技术的能源化利用。未来需强化技术体系整合创新与加强标准规范体系建设,推动市政污泥资源化处理向系统性、安全性、经济性并重的模式转型升级。
To explore the research progress in the field of municipal sludge resource treatment,more than 700 journal papers in WOS database from^(2)008 to 2024 were screened for visual analysis.Scientific knowledge graphes such as the number of publications,national collaborations,institutional collaborations,and keyword emergence were drawn by visualization software of CiteSpace.The results show that the research has shown a stepwise steady growth,and the evolution trajectory is closely related to the policy orientation;China,the United States and other core countries are the major output countries in this field.The leading institution,Chinese Academy of Sciences(CAS)has formed an intensive cooperation network with major research institutions in other countries;The environmental sciences is the subject area with the largest number of publications.The current research hotspots focus on four major technology paths:ecological utilization of soil improvement and functional restructuring by biological transformation,the targeted extraction and high-value transformation of nutrients elements of nitrogen and phosphorus,preparation of environmentally friendly materials,and resource utilization of based on thermal transformation technology.In future,it is necessary to strengthen the integration and innovation of the technical system and the establishment of standards and norms,promote the transformation and upgrading of municipal sludge resource treatment to a mode that emphasizing systematic,safety,and economy simultaneously.
