Innovation in decarbonizing wastewater treatment is urgent response to global climate change. The practical implementation of anaerobic ammonium oxidation (anammox) treating domestic the key reconciling carbon-neutral management with sustainable development. Nitrite availability prerequisite anammox reaction, but how achieve robust nitrite supply and accumulation for mainstream systems remains elusive. This work presents a state-of-the-art review on recent advances anammox, paying special attention available pathways (forward-going (from nitrite) backward-going nitrate nitrite)), controlling strategies, physiological ecological characteristics functional microorganisms involved supply. First, we comprehensively assessed nitrite-oxidizing bacteria control methods, outlining that these technologies are transitioning possessing multiple selective pressures (such as intermittent aeration membrane-aerated biological reactor), integrating side stream free ammonia/free nitrous acid suppression recirculated sludge treatment), maintaining high activity ammonia-oxidizing competing oxygen bacteria. We then highlight emerging strategies supply, including production driven by novel microbes (ammonia-oxidizing archaea complete ammonia bacteria) reduction (partial denitrification nitrate-dependent methane oxidation). resources requirement different analyzed, hybrid pathway combining partial nitrification encouraged. Moreover, data-driven modeling process well proactive microbiome proposed hope achieving application. Finally, existing challenges further perspectives highlighted, i.e., investigation nitrite-supplying bacteria, scaling-up from laboratory under real conditions, stable performance fundamental insights this aim inspire advance our understanding about provide robustly shed light important obstacles warranting settlement.

Published: May 16, 2024

Biological nitrogen removal is a classic technique for removing from wastewater that has been studied extensively and gives high rate, energy efficiency, relatively environmentally benign. Using biological processes to treat the diverse components of requires thorough understanding microorganisms pathways involved. However, information regarding participating in remains limited. This review presents current knowledge researches into these microorganisms, including ammonia oxidizing bacteria, archaea, complete oxidation nitrite-oxidizing anaerobic ammonium denitrifying heterotrophic nitrification-aerobic denitrification bacteria. The metabolic enzymatic reactions involved cycle abovementioned are demonstrated. key enzymes, functional genes, removal-related were discussed. Additionally, advantages different oxidation, denitrifying, HN-AD described. Finally, limitations strategies unraveling presented. aim improve our principle advanced allow possible improvements treatment be identified.
