Abstract
This experiment was conducted to find out the optimum condition of aeration rates for removal of malodor and to improve the compost quality. The aspect of ammonia emission and amounts of volatilization were investigated in the enclosed composting reactor of 242 liters piled with mixed materials of dairy manure and rice straw, which adjusted to 65% of initial moisture content and controlled by four different aeration rates. Mature temperature increased suddenly in initial composting time and decreased with Increasing aeration rates. The treatment of
축분 퇴비화시 악취 경감과 양질의 퇴비생산을 위한 적절한 공기주입율을 설정하고자 밀폐형 반응조(242l)에 우분과 볏짚의 혼합물(65% 수분함량)을 퇴적하고 4처리의 공기량을 주입하여 암모니아 가스의 발생양상과 휘산랑을 구명하였다. 부숙온도는 공기주입율이 증가할수록 감소하는 경향이었으며, 공기주입율이 가장 높았던
