| 摘 要： | 为了解生物滤池/滴滤池在净化含NH3废气过程中N2O排放情况并分析其影响因素。本研究依据Web of Science数据库检索发表于2006—2020年的国内外相关文献报道，并进行归纳总结和数据分析。结果表明:在生物滤池中，填料湿度、填料pH、NH3进气载荷等对N2O排放有着重要影响；在滴滤池中，进气气体组分、NH3进气载荷和滴滤池构造等影响N2O排放。总体而言，生物滤池/滴滤池相关的N2O排放机理尚不清晰，仍需进一步研究。最后，结合生物滤池/滴滤池运行管理的研究成果，本研究就N2O减排提出建议。

| Abstract: | In order to understand the N2O production from NH3-loaded biofilter/biotrickling filter and reveal the underlying influencing factors, this study summarized and analyzed the results from relevant literatures published between 2006 and 2020 according to the data base of Web of Science. The results showed that: Moisture, the pH of packing media, and the ammonia inlet loadings were key factors controlling the N2O formation from biofilters, while in biotrickling filters composition of inlet gas, ammonia loading, and design of biotrickling filter were considered important. In conclusion, it remains unclear about the mechanisms behind N2O production and its microbial pathways from biofilter/biotrickling filter. Further research are necessary to explore the relationship between gas removal and N2O production. In the end, several suggestions are proposed to reduce the N2O production through optimized biofilter/biotrickling operations and use of mitigation methods. |
