Abstract

In this study, loading of optimum leather fleshings was investigated with four identical batch reactors with different fleshings and treatment sludge ratios (0:1, 0.25:1, 0.35:1, 0.50:1) to contribute to the state of art of the biogas production from tannery solid wastes. Results showed that lipids-containing leather fleshings boosted the methane production potential. However, H2S inhibition and volatile fatty acids accumulation were the main concern in the anaerobic digestion of these wastes. The modified Gompertz model was applied to the batch tests data to determine the kinetic constants of anaerobic digestion of tannery solid wastes. It was calculated with the model outputs that the ultimate methane production potential and maximum methane production rate in reactors having mixing ratio of 0.35:1 and 0.5:1 (dry basis) were highly similar. 0.35 was found to be an optimum leather fleshing and treatment sludge ratio with a 54% more methane production potential than that of control reactor in this study.

Özet

Tabakhane katı atıklarından biyogaz üretimi üzerine literatüre katkısağlamak amacıyla yürütülen bu çalışmada deri etleme atığı yükününanaerobik biyogaz üretimine etkisi ve optimum deri etleme atığı yükü,farklı etleme atığı ve arıtma çamuru karışım oranlarıyla (0:1, 0.25:1,0.35:1, 0.50:1) kesikli olarak işletilen dört eşdeğer anaerobik reaktör ileincelenmiştir. Elde edilen sonuçlar, lipit içeren atıkların metan üretimpotansiyelini arttırdığını göstermiştir. Ancak, H2S inhibisyonu ve uçucuyağ asitlerinin birikimi bu atıkların anaerobik olarak çürütülmesindedikkat edilmesi gereken önemli hususlar olarak görülmüştür. Kesiklideneyler ile elde edilen verilere Gompertz modeli uygulanarak buatıkların anaerobik olarak çürütülmesinde kinetik katsayılarbelirlenmiştir. 0.35: 1 ve 0.5: 1 (kuru bazda) karışım oranı ile işletilenreaktörlerin nihai metan üretim potansiyelleri ve metan üretim hızıdeğerlerinin oldukça benzer olduğu model çıktıları ile hesaplanmıştır.Çalışmada, 0.35:1 karışım oranı ile işletilen reaktörün hiç etleme atığıilave edilmemiş kontrol reaktörüne göre %54 daha fazla metan üretimpotansiyeline sahip olduğu ve bu karışım oranının optimum etleme atığıve arıtma çamuru oranı olduğu gözlenmiştir.
