영문 초록

Food waste is becoming by environmental problem nowdays increasing festinately in Korea during past 10 years. Food waste collected from garbage trucks that is offered in S municipal government that food waste mixs enough, and sewage sludge collected in the country. Composting experiment conditions achieved in the mixture ratio rate that food waste and sewage sludge are each 10:90, 30:70, 50:50, 60:40, 70:30 and 90:10 wt%. The fermentation temperature was 18~22oC at the beginning, and then it was sharply increased to 44~66oC up to 1 day after fermentation, which was maintained for more than 3 days. Then, it was slowly decreased to 18~25oC up to 8 days after fermentation, which was maintained all the time. It could be known from examiation of various conditions, including reaction rate, salinity, carbon/ nitrogen(C/N) ratio, temperature, organic substance, etc.. Optimum mixture ratio rate of composting using food waste and sewage sludge was 60:40 wt%.
