Abstract

Abstract

Anaerobic ammonia oxidation(anammox) is the most promising biological nitrogen removal technology in the wastewater treatment process, and biofilm is an effective means to enrich anammox bacteria. However, the formation of anammox biofilm and the enrichment of anammox bacteria usually takes several months or even longer, which hinders the widespread application of anammox technology. This review summarizes a series of methods to enhance the formation of anammox biofilm and enrich anammox bacteria in recent years, focusing on the effects of the selection of carrier types, carrier surface pretreatment methods, biomass fixation technology, reactor types, anammox bacteria activity, and competitive enhancement on the formation of anammox biofilm and the enrichment of bacteria. Based on clarifying the enhancement strategies, this review elaborates on the advantages, disadvantages, and potential application scenarios of each method, and looks forward to the future research directions of anammox biofilm technology, to provide important references for the optimization and application of anammox processes.
