Abstract

In the study, treatment of odorous waste gases emited from the cattle and sheep breeding facilities andpoultry farms which containing ammonia were investigated by means of biofilters. Biofilters are preferredfor odor control due to their low energy requirement and capital cost. For this purpose, bench scale batchreactors, were used to simulate the intermittent ventilation of animal barns. Ammonia/air mixtures used aspollution source were obtained by stripping the concentrated ammonium hydroxide via air and fed to twoserially connected biofilter modules. Compost produced from domestic solid waste and sawdust mixturewas used as a packing material in the filters. Factors affecting aerobic-biologic oxidation of ammonia inbiofilters 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.

Özet

Çalışmada büyükbaş ve küçükbaş hayvan yetiştiriciliği ve kümes hayvancılığı alanlarındaki tesislerden kaynaklanan ve amonyak içeren kokulu atık gazların biyofiltrelerle arıtılması araştırılmıştır. Biyofiltreler, düşük enerji gereksinimleri ve ilk kurulum maliyetinin düşüklüğü nedeniyle koku kontrolünde tercih edilmektedir. Bu amaçla, hayvan barınaklarının aralıklı havalandırma uygulamasının simüle edilmesi amacıyla kesikli düzenle kurulan laboratuvar ölçekli reaktörler kullanılmıştır. Konsantre amonyum hidroksit çözeltileri, hava ile sıyrılarak elde edilen amonyak/hava karışımları seri bağlı iki adet biyofiltre modülüne beslenmiştir. Filtrelerde dolgu maddesi olarak evsel katı atıktan üretilmiş kompost ve odun talaşı karışımı kullanılmıştır. Farklı yükleme oranlarına karşılık amonyağın biyofiltrelerde aerobik-biyolojik olarak oksidasyon verimi ve bu verimi etkileyen faktörler incelenmiştir. Aklimasyon dönemi dahil 130 günlük süre içinde 1,32-27 g NH3/m3.saat aralığında 8 farklı değerde yükleme yapılmış, ortalama amonyak giderim verimi % 97,2±1,8 olarak bulunmuştur.
