Physicochemical Characteristic Analysis of Atmosphere Suspended Particles in the Heavy Industry Peripheral Area

Chou, Yu-kuang 09 September 2009 (has links)
Kaohsiung city for the south Taiwan industry strategic place, the Siaogang area is a heavy industry stands in great numbers the area, the rendering plant, the steel plant, petrifies the factory, the incineration plant, the shipyard, the airport and so on, moreover also has transport means and so on the container truck, carriage vehicle, airplane, The air quality fraction defective occupies crown of the whole city. Kaohsiung important empty unclean control key of suspended particulate pollution, This research is for the purpose of discussing Physicochemical characteristic analysis of air suspended particles in the heavy industry peripheral area, understood in the heavy industry peripheral area air the suspended particles pollutant originates. Physicochemical characteristic analysis discussion atmosphere pollutants to influence Siaogang area. This research in May 2009 period picks each time continual sampling 24 hours to carry on each week twice sampling respectively, the East, West, South and North central area average in the Siaogang area 5 points, altogether gathers 20 samples. Another gathers motorcycle/automobile/diesel car/boiler/voltaic arc boiler/fritting furnace/road dusts different of samples, altogether 14 samples. This research uses air sampling instrument (GAST) carries on the sampling to air of the Siaogang area. Using the scanning type electron microscope (Scanning electron microscope, SEM) and instruments and so on XRD (X-ray Diffractometer, XRD) carry on the metallic element and the physicochemical characteristic analysis. The time can of because of the Siaogang area atmosphere in the suspended particulate matter origin type and the contribution quantity, relevance of in order to help control of air suspended particles in the heavy industry peripheral area pollutant and the source of pollution. This research the main of purpose this study by under construction in the air in the surrounding areas of heavy industry in the pollutants of sampling technology, and discussion of pollutants by the scene size distribution and inorganic salts, and so particulate surface characteristics and analysis for the structure and composition. This research also use a variety of discussion on the valuable instrument analysis to peripheral areas of heavy industry in the pollutants in air of surface and microstructure characteristics, the result of the above analysis, may further in-depth understanding of the heavy industries in peripheral areas of pollutants characteristics, also took granular than in the air pollutants and other kinds of granular pollutant emission sources and physicochemical characteristics of the apparent, discussion of heavy industry in peripheral areas of major sources of granular pollutants for source decrement measures. Future expected completion of roads, schools, residential, farmland, rivers the downwind side of the land of bare ground, farming, construction site River dust, straw, dead wood, rubber, PVC plastic, PE/PP plastics non-heavy industry surrounding area of micro photo, composition and organizational analysis, and than the judgment against a database of all particulate sources.
