Özet:

 The amount of animal waste resulting from the increase in animal husbandry in our country and in the world has become one of the most important sources of environmental pollution. The use of animal organic wastes in biogas production is an efficient waste management step in waste disposal and energy recovery from waste. In this study, biogas and methane CH4 yield of cattle manure as a result of anaerobic digestion AD in batch reactors under mesophilic conditions were investigated. Then, thermal pretreatments were applied to the AD residue in batch reactors at 60 C, 80 C, 100 C and 120 C for 4 hours. While the CH4 yield of untreated cattle manure was 203.5 mLg volatile solids VS, the cumulative CH4 yield of 120 C thermal pretreated cattle manure was determined as 251.7 mLg VS. Thanks to thermal pre-treatments, the CH4 yield per unit mass of cattle manure was increased by a maximum of 23.6 cumulatively. The dissolution efficiency of lignocellulosic components cellulose, hemicellulose and lignin with thermal pretreatments were investigated. At the same time, at the end of the whole anaerobic process, the total chemical oxygen needs and the removal efficiency of VS amounts were determined. The findings of the study can be used for large-scale biogas plants producing in Turkey.

 Ülkemizde ve Dünyada hayvancılığın artması ile ortaya çıkan hayvansal atık miktarı çevre kirliliğinin en önemli kaynaklarından biri olmuştur. Hayvansal organik atıkların biyogaz üretiminde kullanılması, atık bertarafında ve atıklardan enerji geri kazanımında verimli bir atık yönetimi adımıdır. Bu çalışmada, sığır gübresinin mezofilik koşullar altında kesikli reaktörlerde anaerobik sindirim AS sonucu biyogaz ve metan CH4 verimi incelenmiştir. Ardından kesikli reaktörlerdeki AS kalıntısına 60 C, 80 C, 100 C ve 120 Cde 4 saat termal ön işlemler uygulanmıştır. Ön işlemsiz sığır gübresinin CH4 verimi 203,5 mlg uçucu katı UK iken 120 C termal ön işlemli sığır gübresinin kümülatif CH4 verimi 251,7 mlg UK olarak belirlenmiştir. Termal ön işlemler sayesinde sığır gübresinin birim kütle başına CH4 verimi kümülatif olarak en fazla 23,6 kadar artırılmıştır. Termal ön işlemler ile lignoselülozik bileşenlerin selüloz, hemiselüloz ve lignin çözünme verimleri incelenmiştir. Aynı zamanda tüm anaerobik süreç sonunda toplam kimyasal oksijen ihtiyaçları ve UK miktarlarının giderim verimleri belirlenmiştir. Çalışma bulguları Türkiyede üretim yapan büyük ölçekli biyogaz tesisleri için kullanılabilir niteliktedir.
