| 摘 要： | 污水系统是温室气体氧化亚氮(N2O)的重要排放源,近年来相关的研究工作层出不穷。利用文献计量学方法,系统地分析了2000-2020年污水系统N2O的研究进展。分析发现,污水系统N2O相关论文发表数量逐年增多,且主要来源于中国。早期以N2O的产生过程、污水处理系统与影响因素等研究为主。而近期研究更多关注了污水系统中污泥在堆肥过程中产生与排放的N2O、生物炭在N2O减排上的应用及相关微生物种群的分析。后续研究可进一步关注回收N2O作为能量物质的相关工艺,并尝试将实际污水处理系统大数据与模型工具进行结合,从而对实际污水处理系统的运行及优化提供参考。

| Abstract: | Wastewater system is an important emission source of nitrous oxide (N2O,a potent greenhouse gas).In recent years,relevant research work has emerged one after another.Using the bibliometric method,this paper systematically analyzed the research progress of N2O in the sewage system in 2000-2020.It was found that the number of articles related to N2O in sewage system was increasing year by year,with major contributions from researchers in China.In the early stage,the research mainly focused on the production process of N2O,system and influencing factors.Recent studies had paid more attention to the production and emission of N2O in composting,the application of biochar in mitigating N2O emission,and the analysis of related microbial communities.Subsequent research could further focus on the related processes of recovering N2O as energy material,and attempt to combine the big data of actual wastewater system with modelling tools,which might provide guidance for the operation and optimization of the actual wastewater treatment systems. |
