Industrialization has exerted significant adverse effects on water quality, leading to an increasing demand for environmentally friendly and high-efficiency technologies. The traditional Fenton process has been recognized as a viable method for treating challenging industrial wastewater. Recently, peracetic acid (PAA)-based advanced oxidation processes (AOPs) have emerged as a promising Fenton-like technology for efficient wastewater treatment. To evaluate the potential application of this technology in industrial wastewater treatment, the Fe(II)/PAA and Fe(II)/H
