악취자동측정에 의한 시화 및 반월공단의 악취특성고찰
Abstract
The purpose of this research is to evaluate the odor exhaust characteristics of Sihwa and Banwol industrial complex during one year in 2007 by the automatic odor analyzer. As the continuous monitoring results on the 54 odor items, the highest average concentrations in two complexes were p-diethylbenzene, ammonia, toluene and methylethylketone. The items haven highest contribution rate in Sihwa and Banwol industrial complex were Dimethyl sulfide, i-Valerie acid, i-Valer aldehyde, Valerie acid, Trimethylamine and Etylmercaptan, Hydrogen sulfide, Dimethyl sulfide, Formaldehyde, Trimethylamine. When the odor concentrations converted into the total odor intensity, The percentages of hour data appeared over 3 degree of odor intensity were 0.5% (40 hr) in Sihwa station and 3.0% (210 hr) in Banwol station, respectively. Over 1 degree of odor intensity which is odor threshold value also were 68.3% in sihwa station and 82.5% in Banwol station, respectively. The highest monthly odor intensity was shown in January and February. Therefore, continuous monitoring system for odor compounds through the odor automatic station seems to be the most efficient method for investigating odor exhaust characteristics.
