목초액 처리가 돈분 퇴비화 과정중 악취저감에 미치는 영향 = Reduction of the Odors during Pig Manure Composting Using of Pyroligneous Acid Liquor

다국어 초록 (Multilingual Abstract)

The objective of this study was to investigate the effect of odor removal such as NH_(3), volatile organic acid (VOA) during the pig manure composting using of the Pyroligneous acid liquor (PAL). The odor removal efficiencies were evaluated throughout the dilution rates (x0, x100, x300) of PAL. The results of the study are as followings.
NH_(3) content in all treatments (volume 10L) was approximately 8 mg/kg in compost piles on the first day. In the case of control treatment, it was increased by 46 mg/kg within 10 days and was not detected after 25 days. In contrast, those levels in PA-100 and PA-300 treatments were similar values at 38 mg/kg within 6 days and decreased after 15 days. And GC. equipment was used to analyze the volatile organic acids (acetic acid, butyric acid, isobutyric acid, isovaleric aicd, 2,3-methylbutyric aicd, and propionic acid). The concentration of acetic acid and butyric acid were the higher than other VOAs during the initial composting day and sharply declined after 15 days. The VOAs in the control treatment were detected until 40 days, but PA-100 and PA-300 treatments were not measured after 15 days. The PA-100 in all treatments was the most effective treatment for NH_(3) gas and VOAs reduction during composting.
In addition, these studies for the odor reduction in compost manufacture process would have to research on more effective methods for the PAL utilization in agro-biological aspects
