Abstract
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
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
