摘　　要：由于A^2/O工艺自身存在的不足,导致系统的氮、磷去除难以达到理想的效率。较系统地研究了厌氧/缺氧环境倒置的A^2/O工艺的原理和工艺特点,并通过在某污水处理厂的现场试验,表明倒置A^2/O工艺的脱氮除磷功能明显优于常规A^2/O工艺,其COD去除能力则与常规A^2/O工艺相当。Due to the shortage of conventional A^(2)/O process,it's difficult for phosphorus and nitrogen removal to achieve satisfied effect together.The principle and characteristics of reversed A^2/O process has been studied.And experiments in a wastewate treatment plant has showed that, phosphorus and nitrogen removal rates of reversed A^2/O process are markedly higher than that of conventional A^2/O process, whereas the COD removal rates are about equal.

关 键 词：倒置A2/O工艺 脱氮 除磷
