摘要

The paper describes the results of a systematic study of the transient behavior of biofilters treating reduced sulfur pulping odors and VOCs. They were exposed to variations in contaminant loading and periods of starvation. Three bench-scale biofilters with different filter media were used. Filter media materials used wee the mixtures of compost/perlite (4:1), hog fue/perlite (4: 1), and compost/hog fuel/perlite (2: 2: 1). Hydrogen sulfide, the main malodorous gas pro- duced from raft pulping processes, was used as the test contaminant.
