Treatment of cationic red X-GRL in high-salt printing and dyeing wastewater by an electrocatalytic ozonation system: treatment efficiency and degradation mechanism.

ABSTRACT: High 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. The specific energy consumption of the MgMn _x O _y -GAC/EP system
