A pilot-scale upgraded gravity-driven submerged membrane (GDSM) reactor was constructed to enhance nitrogen removal. It was artificially formed multiple stratified environments (dissolved oxygen (DO) and substrate supply (TOC, TN, COD, NH4+-N, NO2--N, and NO3--N)) by embedding moving water baffles to control water-flow process in bulk liquid with slow-flowing liquid state. Significant diversity and relative abundance of microorganisms associated with nitrogen transformation paths (i.e., ammonia-oxidizing archaea, ammonia-oxidizing b
