description	一种连续流城市污水AOAO自富集厌氧氨氧化实现自养与异养耦合脱氮的装置与方法，属于污水生物处理领域。该装置包括原水水箱、AOAO反应器、二沉池；生活污水和二沉池的部分回流污泥首先进入AOAO反应器的厌氧区，聚磷菌、反硝化聚磷菌厌氧释磷并贮存内碳源；随后部分厌氧末混合液进入AOAO反应器的好氧区，进行吸磷和短程硝化反应，部分厌氧末混合液、全部好氧区混合液与二沉池的部分回流污泥进入缺氧区，通过在缺氧区投加填料利用厌氧末混合液中含有的氨氮和好氧区混合液中含有的亚硝为基质富集厌氧氨氧化菌，在缺氧区发生自养与异养耦合脱氮，随后混合液进入后置好氧区发生短程硝化反应，然后混合液进入二沉池进行泥水分离。本发明实现深度脱氮。 The invention discloses a device and a method for realizing autotrophic and heterotrophic coupling denitrification by continuous flow municipal sewage AOAO self-enrichment anaerobic ammonia oxidation,and belongs to the field of sewage biological treatment. The device comprises a raw water tank, an AOAO reactor and a secondary sedimentation tank; wherein the domestic sewage and a part of return sludge of the secondary sedimentation tank firstly enter an anaerobic zone of the AOAO reactor, and phosphorus-accumulating bacteria and denitrifying phosphorus-accumulating bacteria release phosphorusanaerobically and store an internal carbon source; then, a part of the anaerobic end mixed liquid enters an aerobic zo
