영문 초록

This study investigates the react characteristics to suggest the condition of the utilization and disintegration of food garbage as composting by varying the supply amount of air of the fermentation reactors. With the initial temperature and agitation velocity maintained 50$\circ$C and 1 rpm, the supply amount of air gives variety to 0.5, 1, 2, 4 l/kg$\cdot$ min. In the case of the amount of air operated at the 0.5 l/kg$\cdot$ min, reaction temperature shows a rising to the maximum 66$\circ$C after the 48hr, and the oxygen used rate of the micro-organisms shows the largest level at 18.4% after the 8hr. In the case of $NH_3, H_2, H_2S$ and SO$_2$ among the react gas, the sanitary utilization shows the possibility of the microorganisms gas disintegration, with most high gas generate rate. In the case of the amount of air operated at the 1, 2 and 4 l/kg$\cdot$ min, initial react was advanced rapidly and the product of the 72 hr after shows big weight reduction. As the experimentation result, when the amount of air operated at the 1 l/kg$\cdot$ min over, the reduction by disintegration would be more effectively, for the reactor maintains the color tone and shape of the straw (bulking agent).
