돈분뇨 처리과정에서 발생되는 알데히드 화합물의 발생특성 = Emission Characteristics of Aldehyde Compounds Produced from Swine Excretions Treatment

국문 초록 (Abstract)

돈사에서 배출되는 돈분뇨에서는 다양한 악취화합물이 함유되어있다. 돈분 악취를 저감하는 가장 보편적인 방법은 사료에 사료 보조제를 첨가하는 것이다. 그러나, 그 첨가 효과에 대해서는 다양한 의견이 있다. 본 연구에서는사료 보조제를 첨가한 실험군과 첨가하지 않은 대조군에서 발생되는 알데히드 화합물의 발생특성을 비교하였다.
인큐베이터형의 돈사에 여섯 구획이 나뉘어져 생후 26~28일된 60두의 자돈을 10두씩 넣고 사양실험을 하였다.
5종류의 사료 보조제는 유통 중이거나 개발중인 것을 이용하였다. 각 실험군의 돈분을 넣은 후 악취발생기에서발생된 가스를 headspace로부터 채취하여 GC로 분석하였다. 각 알데히드 화합물의 측정 농도를 최소감지농도로 나누어 주요 악취물질을 추정하였다. 분석 결과 6종류의 알데히드 화합물 (acetaldehyde, propionaldehyde, isobutyraldehyde, n-butyraldehyde, i-valeraldehyde, n-valeraldehyde) 중 95.3%를 차지하는 물질은isobutyraldehyde이었다. 또한, 알데히드 화합물은 황화합물과 트리메틸아민의 저감과 통계적으로 깊은 상관관계를 갖는다

Swine manure discharged from pigery emits various odorous compounds. The most common method to reduce such odors is adding feed additives to swine feeds. However, whether the effects of such methods are truly effective are controversial. This research contrasts the aldehyde compound emission characteristics and removal effects from a treatment group, which were given feeds added with feed additives, to a control group, which were given feeds without feed additives. Sixty swine of age 26~28 days were evenly divided into six sections within an incubator type pigsty - each section contained ten weaners. Five types of feed additives, either currently in the market or in development were supplied. Gases sampled from the headspace in the odor producing reactor were analyzed by GC. Major malodorous compounds were estimated by the concentrations and threshold values from the detected components. Since 95.3% of the odor comes from isobutyraldehyde out of six types of aldehyde compounds (acetaldehyde, propionaldehyde, isobutyraldehyde, n-butyraldehyde, i-valeraldehyde, n-valeraldehyde), it can be regarded as the most critical compound contributing to pigsty odor. Aldehyde compounds showed statistically significant correlation with elimination of sulfide compounds and trimethylamine
