城市排水管网中温室气体减排策略研究进展

Review on emission reduction strategies of greenhouse gases in urban drainage network

通过梳理当前国内外城市排水管网温室气体研究现状,本研究分析了管网微生物特性,阐述了排水管网中温室气体产生机理,在此基础上探讨了CO_(2)、CH_(4)和N_(2)O的物理、化学控制方法(如高铁酸盐等),最后给出了排水管网温室气体减排潜在策略.建议今后应加强天然化学品控制(如尿液)和资源化利用的深入研究,为城市排水系统碳减排提供数据和理论支持.

In this study,microbial characteristics in urban drainage network were introduced,and the generation mechanism of greenhouse gases(GHGs)was analyzed,after summarizing the research status of GHGs in urban drainage networks at home and abroad.Furthermore,the physical and chemical methods(like Ferrate)of controlling CO_(2),CH_(4),and N_(2)O were discussed,and finally,potential strategies for the emission reduction of GHGs in urban drainage networks were given.It is suggested that both natural chemical control(e.g.,Urine)and resource utilization should be studied well to provide data and theoretical support for carbon emission reduction from urban drainage systems in future.
