Porous Ca-doped Al2O3 with Abundant Basic Sites for Enhanced Hydrolysis of Fermentative Antibiotics
The potent antibacterial properties of residual antibiotics in wastewater severely inhibit microbial activity in biological treatment systems, leading to system failure and the enrichment of antibiotic resistance genes (ARGs) in activated sludge. To address this critical issue, this study innovatively integrates a catalytic pretreatment unit in the front of traditional wastewater treatment processes. The P-Ca-Al catalytic system promote the hydrolysis of Ery-A into intermediates with low antimicrobial activity, thereby blocking the generation of ARGs at the source. To validate the pretreatment effect, the production of ARGs under different treatment conditions was systematically monitored.
