碩士 === 大葉大學 === 工學院碩士在職專班 === 99 === This research is a composting test subject of the common organic waste in the elementary school. By utilizing the thermal insulation materials and the existing organic wastes in the campus to study the optimum mixing ratio of different material and the highest efficiency of composting. By adding the mature fraction and organic liquid at the bottom of barrel to study their affection of composting. The study indicated with defoliation as carbon, soybean milk residual as ammonia resource, the optimum mixing ratio is 1 : 2; the optimum mixing ratio is 1 : 3 between defoliation and raw kitchen waste; the best ventilation volume is 1 L air/Kg dry solid-min. It is suggested to maintain the temperature by coating the barrel with Styrofoam in winter. It took only one week for kitchen waste, and two weeks for soybean milk residual to reach the initial stable status.
