- Abstract:
- To investigate the characteristics of antibiotic residues removal in municipal sewage treatment plants, pharmaceutical wastewater treatment plants and hospital sewage treatment facilities, biological aerated filter (BAF) process was built and run under different working conditions. Two sets of BAF columns ran with different antibiotic concentrations and different hydraulic retention time (HRT) respectively, and the pollutants degradation in the effluent were detected. The results of the long?term experiments indicated that when the influent antibiotic concentration was less than 1 mg/L, the removal effect of ammonia nitrogen and COD was stable. When the HRT was 10 hours, the removal rate of tetracycline antibiotics was above 82.5%. Results of high-throughput sequencing showed that at phylum level, Proteobacteria was the main group and had the largest change in abundance. At class level, Alphaproteobacteria, Flavobacteriia and Betaproteobacteria significantly increased in abundance and could adapt to antibiotic wastewater. And at genus level, Acidovorax and Flavobacterium with denitrification function predominated in the system.
