Abstract

This study was conducted to investigate use possibility of pharmaceutical byproducts(process sludge) and waste water sludges as raw materials of organic compost at Fertilizer Official Regulation of Fertilizer Management Law in 2002. All pharmaceutical byproducts were satisfied the standard levels of raw material regulated in organic compost, some waste water sludges were deficient in the level. The content of n-hexane extractable material(HEM) was in byproduct higher than in waste water sludge. This was presumed that the sludge with containing a lot of organic matter was high in HEM content. Of the whole microorganism flora, bacteria was mainly detected, and yeast and filamentous fungi took up less population which was fluctuated depending on the source of sludges. Most dominated bacteria were identified into Genus of Pseudomonas. Pseudomonas syringae and Rathayibacter bathayi was classified as plant pathogenic bacteria.

본 연구는 제약업종 부산물 및 폐수처리오니를 비료관리법의 비료공정규격에 퇴비원료로 활용 가능성을 조사하기 위하여 실시하였다. 공정오니의 성분함량은 퇴비의 원료기준에 전부 충족하였으나, 폐수처리오니 중 일부는 유기물 아연 구리 니켈성분에서 기준에 부적합한 것으로 나타났다. HEMs함량은 공정오니가 폐수처리오니보다 높게 나타났으며, 이는 추출이 쉽게 되는 유기물을 많이 함유하는 오니에서 HEM함량이 높은것으로 추측이 되었다. 오니의 미생물상은 세균이 가장 많이 검출되었으며 효모, 사상균 순으로 낮았으나 전반적으로 슬러지의 종류에 따라 변화의 폭이 상당이 컸다. 오니의 우점세균 동정에서 Pseudomonas 속이 많이 검출되었으며 Pseudomonas syringae, Rathayibacter rathayi 는 식물병원세균으로 분류되었다. 지렁이에 의한 생물학적 평가는 공정오니와 폐수처리오니에서 대부분 100% 생존율을 보였으나, 1개의 업체 폐수처리오니에서 생존율이 극히 낮았다.
