摘要

A two-stage BTF system was established treating odorous off-gas mixture from a WWTP.

The two-stage BTF system showed resistance for the lifting load of H₂S and VOSC.

Miseq Illumina sequencing showed separated functional microbial community in BTFs.

Avoiding H₂S inhibition and enhancement of VOSC degradation was achieved.

Key control point was discussed to help industrial application of the system.
