volatile organic sulfur compounds in off-gas mixture from a wastewater treatment plant using a two-stage bio-tricklingfilter system

Shihao Sun, Tipei Jia, Kaiqi Chen, Yongzhen Peng, Liang Zhang

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 4, doi: 10.1007/s11783-019-1148-x

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.
