The low and unstable performance is still one of the major obstacles for anaerobic digestion, which provokes researchers to develop some strategies improve it. In addition traditional approaches such as co-digestion, pretreatment, recirculation, emerging strategies, namely additive microaeration have also been recognized developed in recent years due update knowledge. Many studies evaluated effect those on digestion performance. However, it lacks a unified analysis induction, especially mechanism different strategies. Therefore, this review presents comprehensive view research progress based latest researches considering five main Critical think summary their mechanism, reactor performance, availability were executed. results demonstrated that contribution mainly balance composition activity hydrolysis, acidogenesis, methanogenic archaea. Recirculation co-digestion mass reaction environments. Pretreatment makes structure substrate (such removing lignin, reducing cellulose crystallinity, increasing substrate-specific surface area) more conducive microbial utilization. strategy varies greatly depending type additive, enhancing interspecies electrons transfer through conductive materials, resisting adverse conditions functional additives, accelerating nutrient absorption by regulating bioavailability trace elements. Although these mechanisms promoting ultimate goal make parameters an ideal status, then achieve among substance, microorganisms water reactor.
