초록
본 연구는 고수분 돈분뇨슬러리를 재료로 하여 톱밥여과 호기성 퇴비화 현장시설의 환경요인과 효율을 구명하기 위하여 퇴비화 과정중 온도, 수분함량, 물질수지, 수분증발량, 침출수 발생량, 퇴비 품질을 조사하였다. 분뇨투입은 퇴비화 초기에는 매일 분뇨를 투입하고
This study was carried out to investigate the operating characteristics, water balance and chemical properties of compost during the composting with pig slurry on-farm trial. The composting plant with sawdust pile filteration was done in a forced aeration inside a house and equipped with a turning machine moving on a rails. The composting pit was 4.6m wide, 53m long and the maximum height was 2m. A field scale aerobic composting facility was tested the composting efficiency of high moisture pig slurry. The sawdust materials remained 6 months. Pig slurry was added to compost pile every other day during 6 months run. The temperature in compost pile and compost house, and input and output of moisture were measured during composting process. The result are summarized as follows; 1. The temperature of compost was varied in range of at
