title: [Research progress in microbiological characteristics in combined N2 removal process by partial nitrification and anaerobic ammonium oxidation].
abstract: Partial nitrification and anaerobic ammonium oxidation is a very significant biological nitrogen removal technology for saving energy and carbon sources. The development of this technology and the community ecology of ammonia-oxidizing bacterium (AOB) and anaerobic ammonium- oxidizing bacteria (ANAOB) using molecular biological methods have attracted growing attention. The paper reviewed the technological mechanism and the effects of key factors such as temperature, pH, dissolve oxygen and free ammonia on the distribution of AOB and ANAOB. It was also introduced that the populations of AOB and ANAOB species and their abundance in various environments. At the end, some suggestions were provided for the development of this technology in the future.
