Abstract
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. Especially, the automatic controls of water content and temperature and the mechanization of the sludge feeding and cast separating were the important factors. In terms of changes in chemical characteristics when the equipments for experiments are operated continuously, the ORP, EC,
본 연구는 지렁이 퇴비화 장치개발을 위한 기초자료 연구를 목적으로 지렁이 퇴비화 장치 연속 운영시 하수슬러지 침출액 및 처리 후 발생되는 분변토의 특성변화를 살펴본 결과 pH는 지렁이 생육에 적합한 5~8의 범위로 나타났으며, 산화환원전위와 전기전도도는 처리 전 후의 값의 차이가 뚜렷하게 나타났다.
