In recent years, the risk of antibiotics in the environment has increased due to the inefficient treatment of antibiotics in conventional wastewater treatment plants (WWTPs). This has resulted in the emergence of antibiotic resistance (AMR), which is becoming a significant public health concern in modern society. Conversely, wastewater treatment plants (WWTPs) have emerged as a pivotal site for addressing the issue, given their role as reservoirs of antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARG). It has been reported that conventional WWTPs employ specialised disinfection processes to disinfect the target water body, yet the efficacy of removing ARBs and ARGs has been found to be inadequate. This paper presents a review of the efficiency of several advanced oxidation processes (AOPs) for the removal of ARBs and ARGs from wastewater. The review focuses on the combined ultraviolet (UV) and H2O2/chlorine/peroxymonosulfate (PMS)/ozone processes, Fenton/Fenton-like/photo-Fenton, ultrasonic, and multiphase photocatalysis. The objective is to provide an analysis of their bacterial inactivation mechanisms and removal effects. It must be acknowledged that the treatment of actual wastewater still presents certain limitations, and that further comprehensive studies are required to ascertain the full potential of AOPs for the removal of contaminants.

摘要

In recent years, the risk of antibiotics in the environment has increased due to the inefficient treatment of antibiotics in conventional wastewater treatment plants (WWTPs). This has resulted in the emergence of antibiotic resistance (AMR), which is becoming a significant public health concern in modern society. Conversely, wastewater treatment plants (WWTPs) have emerged as a pivotal site for addressing the issue, given their role as reservoirs of antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARG). It has been reported that conventional WWTPs employ specialised disinfection processes to disinfect the target water body, yet the efficacy of removing ARBs and ARGs has been found to be inadequate. This paper presents a review of the efficiency of several advanced oxidation processes (AOPs) for the removal of ARBs and ARGs from wastewater. The review focuses on the combined ultraviolet (UV) and H2O2/chlorine/peroxymonosulfate (PMS)/ozone processes, Fenton/Fenton-like/photo-Fenton, ultrasonic, and multiphase photocatalysis. The objective is to provide an analysis of their bacterial inactivation mechanisms and removal effects. It must be acknowledged that the treatment of actual wastewater still presents certain limitations, and that further comprehensive studies are required to ascertain the full potential of AOPs for the removal of contaminants.
