| 摘 要： | 人工湿地技术具有良好的污水脱氮效果，但污水中脱除的氮有可能会以N2O的形式释放到大气中。由于N2O是一种重要的温室气体，随着人工湿地的不断推广应用，其向大气中释放N2O的研究引起国内外的关注。综述了目前关于人工湿地系统N2O的产生机理，从污水水质、环境条件、人工湿地系统以及微生物种群结构四个方面详细论述了国内外关于人工湿地系统释放N2O的影响因子的研究现状，并对该研究领域今后的研究重点进行了展望。

| Abstract: | Constructed wetlands (CWs) have shown unique advantages of nitrogen removal from wastewater. However, the removed nitrogen could be released as N2O, an important greenhouse gas, to the atmosphere. With the increasing application of the CWs, the problem of N2O emission from CWs has gained substantial attention in recent years. This paper provides a review on the production mechanism of N2Oand such factors as influent quality, environmental conditions, CWs and microbial community structure affecting emission of N2O during nitrogen removal from wastewater. Research prospects in the future are put forward and are hoped to be helpful for the researchers in the area. |
