| Summary: | 碩士 === 國立交通大學 === 工學院產業安全與防災學程 === 101 === Besides semi-conductor and display industry, photovoltaic industry is a much potential industry in Taiwan. Because its characteristic is Green Energy-Saving Industry, and there are less and less resources in the world, each country should research and develop in photovoltaic process aggressively. There will be much more waste slurry from wire-saw process. These waste slurry are difficult to be treated, and the charge of treatment is costly. That will make photovoltaic industry much more cost burden and decrease its competitiveness. This study includes three methods on recycling of the waste slurry from wire-saw process at a solar wafer manufactory.
The first work is collecting waste slurry individual. The second is analyzing the character of waste slurry. Then try to recycling of waste slurry according to filtration, distillation, and centrifugation.
According to the result of this study, the oil of waste slurry after filtration can be to substitute for fuel of boiler. The solid of waste slurry after filtration and distillation can recycle back to wire-saw process, but its quality is still not steady. Waste slurry after filtration, distillation, and centrifugation, the renewable oil can be
additive solvent to the industrial of dyes and paints, the renewable silicon carbide can be dopont to the industrial of cement and tile.
