The anaerobic ammonia-oxidizing bacteria and other functional bacteria in anaerobic ammonia-oxidizing granular sludge are subject to a variety of metabolic pathways,which can be explored in depth to enhance the growth and metabolic activity of anaerobic ammonia-oxidizing bacteria and improve the denitrification efficiency of anaerobic ammonia-oxidizing systems.The progress of research on the metabolic pathways of functional bacteria in anaerobic ammonia oxidation granular sludge is presented in detail.The growth of anaerobic ammonia oxidation bacteria in anaerobic ammonia oxidation reactors and the nitrogen removal efficiency of the reactors are characterized by metabolic enzymes,three-dimensional fluorescence spectroscopy and UV-Vis absorption spectroscopy,which can be used to regulate the reaction in a more timely manner.We present a prospect for further research on the anaerobic ammonia oxidation metabolic pathways and characterization methods,and provide a reference for subsequent research on the enhancement and regulation of anaerobic ammonia oxidation reactor performance.
