음식물류폐기물처리시설의 악취관리대책에 관한 연구

This study was carried out to assess and analyze the overall problems of the facilities in recycling and treating of foodwaste on the basis of the unit operation facilities. It proposes effective alternatives for the high profitable management that can meet the regulation of the facilities. The study is composed of several parts including a collection of academic reports, field studies regarding the facilities operated by local government and the private sector, the analysis on odor samples from compost facilities and processing facilities for animal feed from foodwaste. Twenty facilities were surveyed on the field to find out the existing problems and to compare between facilities. Several facilities didn't meet the governmental regulation on some processes, especially the stages of input, storage, odor control and the qualities of final products under the unit equipment operation. The analysis on the odors from the phases of input, shredding and fermentation of a compost facility and processing facilities for feed, the odors from shredding equipments were higher in concentration than the others. The Major odors from the composting facility contained hydrogen sulfide (H₂S), methyl mercaptan (CH₃SH), Dimethyl sulfide ((CH₃)₂S) and Ammonia (NH₃) and the major odors from the animal feed facility contained methyl mercaptan (CH₃SH), Trimethylamine ((CH₃)₃N) and Acetaldehyde (CH₃CHO).
