摘要： Tetracycline (TC) inhibits anaerobic digestion (AD) processes by compromising microbial activity. The resulting antibiotic resistance genes (ARGs) pose significant threats to human health. In this study, pristine biochar (BC), KOH-modified biochar (BCKOH), and FeCl₃-modified biochar (BCFe) were synthesized. The removal efficiencies of TC and ARGs by the three biochars were evaluated in anaerobic digestion systems. The results showed that the BCFe group achieved a cumulative CH4 yield of 440.1 ± 24.2 mL/g VS, representing a 74.52 % enhancement compared to the TC group. The BCFe group achieved nearly complete TC removal in the AD system. In addition, BCFe exhibited a superior saturated adsorption capacity. Microbial community analysis revealed that BCFe significantly enriched Clostridia by 21.41 % compared to the TC group. Macrogenomic analysis showed that BCFe reduced the relative abundance of ARGs such as macB , tetA (58) , oleC , and msbA (approximately 1 %). The superior physicochemical properties of BCFe suggest its potential to facilitate direct interspecies electron transfer during AD. This study presents a straightforward approach for removing TC and ARGs in AD systems and explores their potential mechanisms.
