摘要

Wastewater treatment stands as a cornerstone in preserving public health and environmental integrity by effectively eliminating contaminants and pathogens from wastewater before discharge or reuse. Despite its crucial role, conventional wastewater treatment faces formidable challenges, mostly due to the quick metabolic adaptation strategies bacteria employ, which, among others, contribute to the dissemination of antibiotic-resistant bacteria. In response, recent attention has turned to bacteriophages, viruses with a predilection for infecting bacteria, as potential antimicrobial agents within wastewater treatment facilities. This review critically examines the rise of bacteriophages as an integrated biological tool in wastewater treatment plants, specifically targeting putative opportunistic pathogens that may harbor and propagate drug resistance. The exploitation of bacteriophage applications offers a promising pathway toward robust pathogen control within these facilities, although we still lack demonstrations and pilot-scale experiments. Furthermore, our review delves into a wide range of considerations arising and examines prospective methodologies for future wastewater treatment approaches.
