摘　　要：单级全程自养脱氮(CANON)作为一种新型脱氮生物技术因其低耗高效受到人们的关注,在过去20多年间取得良好发展,工艺逐渐从实验室走向实际工程。基于国内外科研工作者的最新研究成果,逐一概述了工艺的原理、特征、影响因素、启动与运行,并阐述了当前工艺的应用现状以及存在的限制因素,在此基础上对工艺的进一步研究方向和应用前景提出了展望。Completely autotrophic nitrogen removal over nitrite（CANON） has attracted increasing attention because of its essential advantages of low consumption and high efficiency. CANON as a novel biological nitrogen removal process, has been continuously studied and applied to practical engineering over the past two decades. The paper reviewed the technological mechanism, feature, influence factor, start-up species and operation on CANON process which based on the latest progresses have been achieved by researchers. Current application situation and the existing problems in the technology were also introduced. At the end, some suggestions were provided for the development of this technology in the future.
