摘　　要：传统A2/O工艺在保证脱氮效果的同时除磷效果往往不佳。在充分分析传统A2/O工艺的基础上,提出了将缺氧池置于厌氧池前面,厌氧池后设置好氧池的分点进水倒置A2/O工艺。某污水厂的现场试验表明,在COD去除能力与常规A2/O工艺相当的情况下,倒置A2/O工艺的脱氮除磷功能明显优于常规A2/O工艺。Conventional A^2/O process achieve satisfied effect on nitrogen removal chieve satisfied effect on phosphorus removal. Principle and characteristics of conventionalA^2/O process have been studied. In reversed A^2/O process an anaerobic tank is put before anoxic tank and design dividual point infall in aerobic tank after auoxic tank. And experiment in a sewage plant has showed that phosphorus and nitrogen removal rates of reversed A^2/O process are markedly higher than that of conventional A^2/Oprocess, whereas the COD removal rates are equal .
