Abstract: Fenton catalytic oxidation technology generates highly oxidizing hydroxyl radicals, effectively degrading toxic or difficult to degrade organic pollutants in wastewater, especially in the treatment of chemical wastewater such as printing and dyeing, pharmaceuticals, coking, and papermaking, which has significant effects. Explored the challenges faced by this technology, such as low utilization of H2O2 and incomplete degradation of organic matter, and looked forward to future development directions, including catalyst modification, optimization of reaction conditions, and development of new composite processes.
Keywords: Fenton catalytic oxidation technology; chemical wastewater treatment; organic degradation
