The degradation of 30 pharmaceuticals and personal care products (PPCPs) subjected to , /UV, and treatments were investigated using semi-batch tests and evaluated by their pseudo-first-order rate constants. The additional application of UV or during treatment significantly improved the degradation rate of most of the PPCPs. At the same feed rate, /UV treatment exhibited much higher PPCP degradation efficiency than that of treatment. This was probably due to degradation of the PPCPs by , direct UV photodegradation, and OH radicals that formed from the photodegradation of during /UV treatment. PPCP degradation by was also promoted by adding during the treatment. However, when the initial concentration was high during treatment, OH radicals were likely to be scavenged by excess , leading to low PPCP degradation. Therefore, it is important to determine the appropriate dosage during treatment to improve PPCP degradation when adding during treatment.
