Özet:

 Current studies for the anaerobic digestion AD process, the conversion of complex industrial organic wastes into energy-rich biomethane, and its standardization are of interest. Biomethane production by AD of chicken manure is an alternative that complies with this standard. However, mainly the monobiomethane yield of organic chicken manure can be quite low. Therefore, the effect of Cr, Fe and Co addition at concentrations of 0-5, 0-150 and 0-30 mgl, respectively in small-scale batch-type biomethane potential analyzes to increase the AD of chicken manure was discussed. Box Behnken Design of the Response Surface Method was applied to find the most appropriate optimization value. The optimization and model equation were successfully achieved with high accuracy and favorable performance. While the methane yield of untreated chicken manure was 235 mlg volatile solids VS, the biomethane yield under optimum conditions Fe: 28,6 mgL, Co:16,2 mgL ve Cr: 3,66 mgL was found to be 267.5 mlg VS. Methane yield under these conditions was increased by 13.6 compared to the methane yield untreated. This study showed that the addition of trace elements Cr, Fe and Co to the anaerobic environment in batch systems and on a laboratory scale successfully increased the methane yield of the substrate. For this reason, future studies need to test the methane yield by adding Cr, Fe and Co trace elements to the anaerobic environment on a pilot scale.

 Anaerobik sindirim AS süreci, karmaşık endüstriyel organik atıkların enerji açısından zengin metana dönüştürülmesi ve bunun standartlaşması için güncel çalışmalar ilgi çekicidir. Tavuk gübresinin ASi ile metan üretimi bu standartta uygun bir alternatiftir. Ancak, esas olarak organik tavuk gübresinin tekli metan verimi oldukça düşük olabiliyor. Bu nedenle, tavuk gübresinin AS verimini arttırmak için küçük ölçekli kesikli tipte metan potansiyel analizlerinde Cr, Fe ve Co ilavesinin sırasıyla 0-5, 0-150 ve 0-30 mgl konsantrasyonlarında etkisini tartışıldı. En uygun optimizasyon değerinin bulunması için Cevap Yüzey Yönteminin Box Behnken Tasarımı uygulanmıştır. Optimizasyon ve model denklemi yüksek doğrulukta ve uygun performansta başarılı bir şekilde elde edilmiştir. Ön işlemsiz tavuk gübresinin metan verimi 235 mlg uçucu katı UK iken optimum koşullardaki Fe: 28,6 mgl, Co:16,2 mgl ve Cr: 3,66 mgl metan verimi 267,5 mlg UK değerinde bulunmuştur ve bu koşullardaki metan verimi ön işlemsiz metan verimine göre 13,6 kadar artırılmıştır. Bu çalışma kesikli sistemlerde ve laboratuvar ölçekte Cr, Fe ve Co iz elementlerinin anaerobik ortama eklenmesi ile substratın metan verimini başarılı bir şekilde artırdığını gösterdi. Bu nedenle gelecek çalışmaların pilot ölçekte Cr, Fe ve Co iz elementlerinin anaerobik ortama eklenmesi ile metan veriminin test edilmesi gereklidir.
