Abstract
In this work, an attempt is made to understand the actual conditions of malodor occurrence for industrial complex area and to settle trouble for a odor complaint. Odor emission sources were sorted into point source and area source group. The odor concentration unit (o.u/㎥) of each major odor emitting industry was actualized by the indirect olfactory method including air dilution sensory test method in Korea and triangle odor bag method in Japanese. As the results, Night-soil disposal plant were measured by the highest of 2,097,992.6 o.u/㎥, and wastewater incinerator plant was analyzed by 315,022.5 o.u/㎥, and food company was analyzed by 210,864 0.u/㎥, and paper products plant was detected by 195,525 o.u/㎥ and chemical product was detected by 13,761.6 o.u/㎥. To evaluate how well the evaluation result of odor made by induced odor concentration (o.u/㎥) can explain the actual odor phenomenon, it was used as the input data of air pollutant diffusion model (ISCST 3) to set model operation time as one hour in consideration of the characteristics odor varying with weather condition at any time. It was confirmed that 2.0 degree of odor intensity could be detected at the neighboring area of industry complex area and 1.7 degree of odor intensity could be detected at the neighboring domestic area. Accordingly, the evaluation result by induced odor concentration (o.u/㎥) could precisely explain the current status of the field with odor problem and sufficiently be used as inputting data for air pollutant diffusion model.
