Abstract

This paper presents an experiment to examine the possibility of treating carcass while making compost with a horizontal cylinder composting equipment. The findings were as follows: as for heavy metal content, zinc content was above the allowed level in some measuring sections of the general operation and the entire measuring sections of the carcass operation, whose copper content was higher than the general operation. The wood chip operation was lower than the allowed level in all the heavy metals and similar or the same as the carcass operation in copper, cadmium and arsenic. Its nickel content was 29.5~63.8%, which was relatively higher than 9.3~18.0% and 15.8~18.0% of the general and carcass operation, respectively. Its chrome content was 14.2~31.9%, which was relatively higher than that of the general and carcass operation. The integrated operation was lower than the allowed level in all the heavy metals. Its copper and zinc content was 34.9~54.5% and 53.1~75.9%, which was similar to 48.9~52.6% and 64.6~85.9%, respectively, in the wood chip operation. Its chrome and nickel content was stabilized while their content was rather high in the wood chip operation. The average and final moisture content of the carcass operation was 60.7% and 49.6%, respectively. Its average moisture content was a little bit higher than the recommended level of 55.0%, but its final moisture content was lower than the recommended level. The average and final moisture content of the integrated operation was 29.2% and 18.6%, respectively, which was the lowest level among the four operation modes. The overall moisture content of the operation modes was under the recommended level of 55.0% with some variance among the modes. The C/N ratio was the lowest in the carcass operation and the highest in the general operation. The average C/N ratio of the operation modes was in the range of 13.7~20.3 with the total average of 18.3, and the modes kept it under the proper level of 30.0.

본 연구는 수평 원통형 퇴비화 장치를 이용하여 퇴비를 생산할 때, 폐사축을 동시에 처리할 수 있는 가능성 여부를 판단하기 위하여 실험을 진행하였다. 그 결과 중금속의 경우, 아연의 함유량이 일반 운전의 일부 측정구와 폐사축 운전의 전체 측정구에서 허용함유량 보다 초과하는 것으로 나타났다. 특히 폐사축 운전의 경우, 구리 함량도 일반 운전에 비해 높게 나타났다. 우드칩 운전의 경우, 모든 중금속이 허용치보다 낮게 나타났으며, 구리, 카드뮴 및 비소의 경우는 폐사축 운전과 유사하거나 동일 수준으로 나타났다. 단지 니켈의 함유량이 29.5~63.8% 정도로써 일반 및 폐사축 운전에서 각각 9.3~18.0% 및 15.8~18.0% 정도 함유한 것에 비해 상대적으로 높게 나타났다. 그리고 크롬의 경우도 14.2~31.9% 정도로서 일반 및 폐사축 운전에 비해 상대적으로 높게 나타났다. 통합 운전의 경우도 모든 중금속이 허용치보다 낮게 나타났으며, 구리와 아연의 함유량은 각각 34.9~54.5% 및 53.1~75.9% 정도로서 우드침 운전의 경우인 48.9~52.6% 및 64.6~85.9% 정도와 유사하였다. 그리고 우드칩 운전에서 다소 높게 나타났던 크롬과 니켈의 함량도 안정화 된 것으로 나타났다. 함수율은 폐사축 운전의 경우, 평균 및 최종치가 60.7% 및 49.6% 정도로서 평균치가 권장치인 55.0% 보다 다소 높게 나타났지만, 최종 함수율은 권장치인 55.0% 보다 낮게 나타났다. 통합 운전의 경우, 평균 및 최종 함수율이 각각 29.2% 및 18.6% 정도로서 4개의 운전 중에 상대적으로 가장 낮게 나타났다. 그리고 운전별로 다소차이는 있지만, 전체적으로 권장치인 55.0% 보다 낮게 나타났다. C/N비의 경우, 폐사축 운전에서 상대적으로 가장 낮게 나타났고, 일반 운전에서 가장 높게 나타났다. 운전별로 보면, C/N비의 평균치가 13.7~20.3 정도의 범위이고, 전체평균이 18.3 정도로서 전체적으로 적정치인 30.0 이하를 유지하였다.
