Anaerobic ammonia oxidation (anammox) technology: A review of application issues

摘要

Anaerobic ammonia oxidation (anammox) is a novel autotrophic denitrification process, which has outstanding advantages in treating low C/N ratios and high concentrations of ammonia wastewater. This paper reviewed the research issues of anammox application, including the principles, microbial classification and properties, seed sludge, reactor types and processes. The optimum running parameters should be investigated in detail due to the complicated application cases. Especially in industrial wastewater treatment, anammox is deemed as the substitute process for the conventional nitrification-denitrification process, and the integrated process is expected to realize the industrialized expansion application. On the other hand, bacterial diversity and functional analysis are extremely important; however, the co-existing bacteria are still largely unknown in the anammox reactor.
