This study was performed to define the physicochemical characteristics of food waste and food wastewater, and to find the effect of moisture content variation and salinity variation on aerobic composting for food wastes. In moisture content variation experiment, the samples of 2-1, 2-2, 2-3 and 24 were prepared by the moisture content of 83.8%, 70.9%, 64.8% and 45.1%, respectively. In salinity variation experiment, the samples of 3-1, 3-2, 3-3 and 3-4 were prepared by the salinity of 0.99%, 1. 69%, 1.75% and 2.34%, respectively. In both experiments, aerobic composting reactors were operated by the mode which was composed of half an hour s stirring and 2 hour s aeration per day, for 45 days. The followings are the conclusions that were derived from this study. 1. In the study of physicochemical characteristics of food waste and food wastewater, the values of pH were 4.19 and 3.96, the values of salinity were 0.91% and 1.17%, and the values of conductivity were 7.6 mS/cm and 18.2 mS/cm, respectively. 2. In food waste, the moisture content was 60.3%, organic compound content was 96.1%, total carbon was 48.0%, total nitrogen was 1.5%(therefore, C/N ratio was 32), and the concentration of total phosphorus was 1.34 mg/kg. 3. The time of temperature ascending was delayed, the highest temperature was lowered, the duration period of high temperature was shortened by the increasing of moisture content. In the higher moisture content, anaerobic condition was formed, bad smell was released, insects were gathered and multiplicated, and the reaction rate of composting was reduced. 4. In moisture content experiment, C/N ratios were changed from the range of 31.2-34.8 at the beginning phase to that of 20.4-28.4 at the last phase. 5. In salinity experiment, the reduction rate of volume was increased(40.3%) when the salinity was decreased(0.99%). Also, the reduction rate of mass was increased(51.8%) when the salinity was decreased(0.99%). This fact denotes that salinity hinders the process of composting. 6. the concentrations of total nitrogen and total phosphorus were increased from 0.74% to 1.10%, and from 0.82 mg/kg to 3.44 mg/kg, respectively when the salinity was decreased from 2.34% to 0.99%.
