Abstract
This study was conducted to induce the optimal composting conditions of pig manure mixed with sawdust and dried paper-mill sludge in the composting for production of high quality compost. Pig manure contains high water content and How C/N ratio because of comparatively high nitrogen content than sawdust and dried paper-mill sludge. Therefore the addition of dried paper-mill sludge and sawdust to the raw materials helps controlling the C/N and the water content of compost pile. The composting system used in the experiment was agitated static bed system. The physical properties of the mixed raw materials was not good at the working conditions in the early stage of composting. The temperature of compost heap reaches at
본 연구는 고품질의 퇴비 생산을 목적으로 건조된 제지슬러지와 톱밥을 돈분에 혼합하여 합리적인 퇴비화 조건을 도출하기 위해 실행되었다. 돈분은 톱밥과 건조 제지슬러지보다 비교적 높은 질소함량으로 인한 낮은 C/N율과 과다한 함수율이 특징이다. 그러므로 건조 제지슬러지와 톱밥을 첨가하여 퇴비더미의 C/N율과 수분함량을 조절하였으며, 퇴비화 방식은 교반 정체식을 이용하였다. 퇴비화 초기 혼합된 퇴비더미의 물리적 특성 때문에 작업성이 용이하지 않았으나 곧 회복되었다. 돈분과 톱밥을 혼합한 P-2 처리구(56.6 : 43.4)는 퇴비화 시작 후 5일 이내에 퇴비더미의 온도가
