biostudies-literatureUnknown15(13)Shang ZHigh salt concentrations in printing and dyeing wastewaters significantly influence pollutant removal. The function of the electrocatalytic ozonation (MgMn x O y -GAC/EP) system in removing pollutants from high-salt printing and dyeing wastewater was investigated. Under high NaCl concentration, the H2O2 yield in the electrochemical system was maintained at approximately 53 mg L-1. Under optimal treatment conditions, the degradation efficiency of cationic red X-GRL in the MgMn x O y -GAC/EP system reached 100% within 16 min, and the mineralization efficiency achieved 90.8% within 60 min.
