New insights into the inhibition performance and mechanisms of sodium dodecyl benzene sulfonate (SDBS) on nitrogen removal in activated sludge-biofilm system

Effect of sodium dodecylbenzene sulfonate on activated sludge systems.To investigate the effect of sodium dodecyl benzene sulfonate (SDBS), a common constituent in electroplating wastewater, on nitrogen (N) removal performance and biological mechanisms, a gradient of SDBS concentrations was introduced into a set of sequencing batch biofilm reactors (SBBRs).
