摘　　要：论述分析了废水生物除磷电子受体从氧到硝酸盐和亚硝酸盐的衍变过程及其相应的典型工艺形式,提出并建立了连续流亚硝化/反硝化聚磷生物除磷新工艺。该工艺具有两个关键点,一个是亚硝化段内亚硝酸盐的稳定积累,另一个是缺氧段中以亚硝酸盐为电子受体超量摄取磷。与常规的反硝化除磷技术相比,亚硝化/反硝化聚磷生物除磷工艺中引入了短程硝化技术,更加节约能耗、减少污泥排放量,具有重大的理论意义和应用价值。The evolution of electron acceptors from oxygen to nitrite and nitrate in the systems of biological phosphorous removal from wastewater and the relevant typical processes were summarized and analyzed, and a new biological phosphorous removal process called continuous flow nitrosification/denitrifying phosphorous accumulation process was proposed and set up. The said process has two key points, one is the stable accumulation of nitrite in the nitrosification phase, the other is the excessive acceptor in anoxic phase. Compare with conventional denitrifying phosphorous adsorption with nitrite as electron phosphorous removal process, the combination process of nitrosification/denitrifying phosphorous accumulation and short-cut nitrification can save more energy and reduce sludge discharge, which has important theoretical meaning and application value.
