Abstract
Serial basic tests were conducted for the determination of fundamental kinetics and for the actual application of kinetic parameter to food waste digestion with precise measurement of methane production under a thermophilic condition. The effects of food particle size, sodium ion concentration, and volatile solid (VS) loading rate on the anaerobic thermophilic food waste digestion process were investigated. Results of serial test for the determination of fundamental kinetic coefficients showed the value of k (maximum substrate utilization rate coefficient) and KS (half-saturation coefficient) as
일련의 회분식실험을 통하여 음식폐기물의 동력학상수 및 메탄가스 발생량을 측정하였으며 음식폐기물의 고온혐기성 소화시 입자의 크기, 나트륨이온의 농도, 휘발성 고형물의 부하량이 따른 운전인자에 대한 영향을 살펴보았다. 기초 동력학 실험에서는 최대 기질 분해 속도 상수 k는
