摘要
垃圾堆填是垃圾处理重要方式之一,其过程会产生大量渗滤液,垃圾渗滤液溶解性有机质(landfill leachate dissolved organic matter,LL-DOM)是垃圾渗滤液产生环境风险的主要来源。为探究LL-DOM的研究热点与前沿,基于文献计量与数据可视化分析软件Cite Space对Web of Science数据库进行了文献统计分析。结果表明,研究热点主要有吸附、腐殖质、污水污泥研究、平行因子分析、微生物群落、荧光光谱、混凝絮凝工艺等;过去20年的主要研究内容包括了渗滤液溶解性有机质组分识别及处理工艺优化研究两方面。结合文献调研分析认为,新兴表征方法及其数据处理、结果分析方法的研究与发展是进一步识别LL-DOM不同种类污染物的关键;同时,多种技术组合,以生物处理和物理化学技术互补的方式进行LL-DOM处理,比单一处理技术综合效果更为理想。
The garbage filling is the important way of landfill treatment that produce a large amount of leach.Landfill leachate dissolved organic matter(LL-DOM)is the main source of environmental risk of landfill leachate.In order to know the research hotspot and frontier of LL-DOM,literature statistical analysis was carried out on the Web of Science database based on Cite Space.The results showed that the research focused mainly on adsorption,humic substance,sewage sludge,parallel factor analysis,microbial community,fluorescence spectrum,flocculation and flocculation process.In the past 20 years,the main research contents included the identification of dissolved organic matter components in leachate and the optimization of treatment process.Based on literature research and analysis,it was concluded that the research and development of emerging characterization methods,data processing and result analysis methods were the key to further identify different types of LL-DOM pollutants.At the same time,the combination of multiple technologies and the complementary way of biological treatment and physicochemical technology for LL-DOM treatment was more ideal than the comprehensive effect of single treatment technology.
