Simultaneous removal of hydrogen sulfide and volatile organic sulfur compounds in off-gas mixture from a wastewater treatment plant using a two-stage bio-trickling filter system

Abstract
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.
