BIOGAS PRODUCTION PROCESS’S KINETICS OF FARM’S POULTRY DUNG

Abstract

Abstract. Biogas production process’s kinetics of farm’s poultry dung (FPD) in
thermophylic conditions has been studied. Total gas volume for 29 days of
fermentation in control variant didn’t exceed 84.5 L, while with addition of 10% and
20% of balanced thermophylic methanogenic microorganisms’ association’s
(BTMMA) inoculate into FPD was 1.7 and 2.1 times higher and amounted to 151 L
and 179 L, respectively. It was established that in trial samples maximal methane
formation during fermentation process reached to 69.7 and 64.7%, respectively. It was
found that in thermophylic fermentation system no bacteria belonging to the
Enterobacteriacea family and other pathogens have been detected.
