Abstract：
:Anaerobic bottle experiments were conducted in parallel for 120 consecutive days to perform the bioaugmentation hydrolysis of selected nitrogen heterocyclic compounds (NHCs) in coal gasification wastewater. Due to enhancement with PAC and Fe(OH)3@PAC, quinoline, pyridine, and indole were hydrolyzed more effectively. The addition of PAC and Fe(OH)3@PAC improved the coagulation capacity of microorganisms, which laid a solid foundation for the removal of selected NHCs and the adverse environmental conditions. Anaerobic degradation of the NHCs occurred first through hydrogenation, then through the opening of the nitrogen heterocycles, followed by the release of ammonia nitrogen and finally the opening of the benzene rings. Enriched Acinetobacter, Levilinea, Comamonas, and Longilinea were the main functional groups responsible for the anaerobic biodegradation of the selected NHCs.
