| Summary: | 碩士 === 嘉南藥理大學 === 環境工程與科學系 === 105 === Fishery feedstuff are made of lower-classed fishes with less economic or the rinsing of seafood or freshwater products. Within the procedure of cooking, liquid and solid separation, and drying, the emission of the dryer machine, containing trimethylamine and other odorous gas or substances, usually are the major sources of the odor and have been a public concern. The neighbors living around the fishery feedstuff plant always complain the bad smell and odor could reduce the environmental quality. The aims in this study was to find out and measure the emission sources of the odor and fine particle during the procedure of manufacturing fishery feedstuffs.
Analyzing the procedure of manufacturing fishery feedstuffs, the odor and particulate matters in 6 locations such as raw warehouse, well-package house, blending procedure, and business office in factory, the position about 100 to 200 meters away from the upwind and downwind of plant also were sampled individually.
In case of this study, each location had various odor concentration within 3 different working time, the average odor value was 256 at blending procedure, 194 at raw warehouse and 114 at well-package house. The odor standard around ambient air is 30 at industrial and agricultural area. It is obvious that this fishery feedstuff plant should consider the available control technology or devices to reduce the odor emission to improve the troubled pollution.
