Along with the enhancement of amount and degree of wastewater treatment, the emission of N₂O will increase accordingly. The establishments of mathematical models for N₂O emissions from the biological nitrogen removal processes in WWTPs have important theoretical and practical significance on the thorough investigations on the mechanisms of N₂O production and the development of N₂O reduction strategies. The present paper summarized the principals of various biological nitrogen removal processes and systematically elaborated the production mechanisms of N₂O and the types, establishment methods and applications of mathematical models simulating N₂O emissions. Furthermore, conclusions were achieved based on the research status and perspectives on future research directions were presented to gain a better modeling of N₂O emissions and to provide supports for the reduction of N₂O emission, the optimization of the biological nitrogen removal processes and the sustainable development of WWTPs. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
