영문 초록

This study was performed to evaluate the effect of aeration rate on cornposting of mixture of swine feces and newspaper. This study was accomplished by operating 4 experimental cornposting reactors of bench scale for 3 weeks. The followings are the conclusions that were derived from this study. 1. As the aeration rate increased from 200 to 500 ml/min$\cdot$kg_vs, the efficiency of composting was increased. But the aeration rate more than 500 ml/min$\cdot$kg_vs did not influence effectively. 2. The range of the highest temperatures of reactors was 51.8~55$\circ$C. Those were not significantly different one another. 3. Increasing rates of ash content namely, reaction rates of composting were proportionally increased by increasing aeration rate from 200 to 1500 ml/min$\cdot$kg_vs. 4. Contents of heavy metal in the final compost were. lower than those of Korean and European standards. 5. Concentration range of T-N in the final composts was 1.7~2.18 mg/kg, and that of T-P was 1.57~7.49 mg/kg.
