摘要：In the study, treatment of odorous waste gases emited from the cattle and sheep breeding facilities and poultry farms which containing ammonia were investigated by means of biofilters. Biofilters are preferred for odor control due to their low energy requirement and capital cost. For this purpose, bench scale batch reactors, were used to simulate the intermittent ventilation of animal barns. Ammonia/air mixtures used as pollution source were obtained by stripping the concentrated ammonium hydroxide via air and fed to two serially connected biofilter modules. Compost produced from domestic solid waste and sawdust mixture was used as a packing material in the filters. Factors affecting aerobic-biologic oxidation of ammonia in biofilters were investigated for different loading rates. During the 130 days which including the acclimation period, 8 different loads were loaded in the range of 1.32-27 g NH3/m3.h and the average ammonia removal rate was found as 97.2% ± 1.8.
其他摘要：Çalışmada hayvan çiftliklerinden kaynaklanan ve amonyak içeren kokulu atık gazların biyofiltrelerle arıtılması araştırılmıştır. Biyofiltreler, düşük enerji gereksinimleri ve ilk kurulum maliyetinin düşüklüğü nedeniyle koku kontrolünde tercih edilmektedir.
