تأثير المعالجة الأولية الميكانيكية لفرشة الدواجن في إنتاجية الغاز الحيوي

Abstract EN

Poultry litter is an organic waste in Syria which can be a source of clean energy if treated anaerobically.

This research aimed to investigate the effect of mechanical pretreatment of poultry litter in producing biogas and methane.

Experiments were performed in units of fermentation laboratory on samples ground spread over parts diameters 1 mm, 3 mm, and 10 mm at at 37°C temperature, for a period of 42 days and compared with untreated samples mechanically.

The results showed that mechanical pretreatment on poultry litter substrates by reducing their size to 1mm, 3mm and 10 mm diameter pieces led to a significant increase in the production of biogas and methane compared with untreated substrates which amounted to produce 244.98 lN kg-1 OTS biogas and 116.77 lN kg-1 OTS of methane.

The results also showed that mechanical pretreatment by grounding the substrates into 1mm diameter pieces was the best mechanical method of treatments resulted with total production of biogas 469.73 lN kg-1 OTS and led to increase producing of methane by 96.6% compared to untreated substrates.
