Abstract

Ammonia and hydrogen sulfide in odorous gases are treated with gas phase biofilters. Packing media used as bilfilm support are active carbon and ceramsite. Sludge in wastewater treatment plant is used as inoculants and biofilter efficiency when ammonia is inducted is tested,relief gases at different heights and when the induction is varied are also tested; reactor performance control has also been considered. The result is that biofilter can be used to treat ammonia and hydrogen sulfide together with good result.
