摘　　要：用生物过滤法处理恶臭气体中大量存在的H2S和NH3。采用污水处理厂的活性污泥进行驯化和培养,以活性炭和陶粒作为填料,考察了运行初期,由于NH3加入对已驯化效果良好的H2S滤柱的影响,不同滤柱高度的出气效果,不同进气浓度的处理效果以及运行过程中的调控情况。结果表明,生物过滤法对H2S和NH3的去除是可行的,效果良好。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.
