초록
Various odor reduction systems are being operated at pig houses to improve livestock odor issues. However, the quantitative evaluation of odorreduction efficiency is not sufficiently conducted. The analysis of factors that affect the reduction efficiency also has not been sufficiently conducted. Therefore, in this study, the reduction efficiency of representative odor reduction facilities (bio-curtain, scrubber) operated by domestic pig houses wasevaluated. The odor reduction efficiency was evaluated by sampling the air before and after the odor reduction facility in 6 pig houses. Livestock odorswere evaluated for complex odors, ammonia, hydrogen sulfide, and VOC. To find factors for reduction efficiency, temperature, humidity, pH of washingresolution, type of washing water, and ventilation rate was measured. As a result, it was found that the scrubber system had the highest reductionefficiency. The reduction efficiency was found to be affected by the scrubber’s washing resolution, filler, operating conditions, and size. Bio-curtainsmay have problems such as deterioration of fan performance due to ventilation fan load, groundwater pollution, and excessive use of groundwater.
