초록
본 연구는 하수슬러지 지렁이 퇴비화 장치 개발을 목적으로 재래식 지렁이 이용기술의 문제점 개선 및 지렁이 생리 생태를 이용하여 제작된 소규모 지렁이 퇴비화 장치의 성능평가을 통한 현장 적용 가능한 장치 설계 및 운영지표 설정을 위한 실험 결과 실험장치 성능평가에서는 하수슬러지 급이시 입자크기와 먹이 공급 층의 높이가 각각 5mm 크기와 10cm 두께로 급이 할 때 처리율이 가장 높았으며, 지렁이 적정 밀도는 20~25kg
The on-site sewage sludge vermicomposting equipment was designed and evaluated on the batch and continuous tests. The vermicomposting equipment was designed to consider the mechanization as well as automation. In terms of performance evaluation of equipment with continuous experiments, the highest treatment rate was found in the condition of 5mm in particle size and 10mm in e feeding height. Also, 20~25kg of earthworm per 50kg of sewage sludge was the most appropriate density of earthworm. In addition, the most effective separation of cast was found when the earthworm breeding box height was 80cm. The performance evaluation on equipment allowed the establishment of earthworm composting capacity of 2ton per a day with a size of
