摘要:當前許多城市和地區(qū)由于排水系統(tǒng)不完善，管網(wǎng)混接錯接現(xiàn)象嚴重，城市水體降雨污染問題普遍存在。基于此，考察了華北地區(qū)典型城市河道溫室氣體（CO2、CH4和N2O）排放情況，并分析了夏季降雨污染影響水體溫室氣體排放的特征和機制。結果顯示，夏季雨后城市河道表層底泥的氧化還原電位（ORP）下降明顯，雨后河道溫室氣體排放通量激增，河道釋放溫室氣體產(chǎn)生的全球增溫潛勢（GWP）是雨前的160.6 倍，并伴隨河道污染物的增加；河道底泥是溫室氣體主要產(chǎn)生和釋放源，且河道溫室氣體釋放量與表層底泥ORP變化密切相關。另外，氨氮、ORP、溫度等環(huán)境因素與水體溫室氣體排放顯著相關。
Abstract:Currently, owing to the inadequate drainage system in numerous cities and regions, the issue of improperly connected pipe networks is prevalent, leading to widespread rainfall-induced pollution of urban water bodies. This study investigated the greenhouse gas (CO2,CH4, and N2O) emissions from a typical urban river channel in North China and analyzed the characteristics and mechanism of summer rainfall-induced pollution affecting theses emissions. After the summer rainfall, the oxidation-reduction potential (ORP) of the surface sediment in the urban river channel decreased significantly, and there was a significant increase in greenhouse gas emission flux from the river channel. The global warming potential (GWP) caused by greenhouse gas emission from the river channel was 160.6 times higher than that before the rainfall. Additionally, pollutant concentrations in the river channel also increased. The river sediment constituted the primary source of greenhouse gas production and emission, with the release of greenhouse gas from the channel being intricately linked to variation in the ORP of the surface sediment. Furthermore, environmental parameters such as ammonia nitrogen, ORP and temperature were significantly correlated with greenhouse gas emissions from the river.
