廢棄物(高汞燈及集塵灰)資源化技術暨附加價值提昇研究計畫
| 中文摘要 | 本計劃賡續「94年度廢棄物資源化技術暨附加價值提升研究計畫」之工作內容，進行高汞燈管及煉鋼集塵灰資源化技術之研究，於前一年計畫中蒐集國內外高汞燈管及煉鋼集塵灰資源化技術之文獻，決定最佳可行資源化技術後，本年度乃規劃建置實驗設備、確立最適實驗操作條件並依據實驗成果提出建議。 高汞燈管之研究成功處理曝光燈與UV燈及日光燈排氣管中之汞，處理效率高達99.9%，日光燈含汞螢光粉中汞之處理效率亦能達80%以上，而較為棘手之冷陰極燈管螢光粉經由實驗室分析之後，發現處理效率不佳之原因為製程中之汞齊所致，未含汞齊之純冷陰極燈管螢光粉加熱200℃即能將大部份汞去除，而含汞齊之冷陰極燈管螢光粉雖加熱至700℃仍持續有汞揮發出來。本研究建議未來除應加強管制冷陰極燈管廢棄物外，冷陰極燈管廢棄物與汞齊更應分開處理。 在煉鋼集塵灰之研究方面，本研究已成功由碳熱還原法之尾氣中收集晶粒大小分布在80 nm ~ 2 μm且晶型完美之氧化鋅棒，並以處理後集塵灰粉末製備合成BaFe12O19磁性材料，未來將以適當之添加物及控制燒結條件，以提昇其矯頑磁場及殘餘磁化強度，而純化過程中之副產品如還原鉛、鎘沉澱物，因國際基本金屬包括鉛、鎘價格均上揚，其儲存、利用及管理未來亦應加以考慮。 本研究並訂定汞及氧化鋅產品之資源化品質規範以協助國內環保產業技術升級，回收之汞產品其純度若能達到99.99%，則可完全再利用，另煉鋼集塵灰經處理後，其產品中氧化鋅之純度若能達55%以上，亦可視為產品販售，朝向「資源全回收零廢棄」之目標邁進。 | ||

A Study of Waste-to-Resource(Mercury-Containing Lamps and Electric Arc Furnace Dust) Technologies and the Enhancement of Value Addition Project
| 英文摘要 | Investigating the advanced recycling technology of waste, this project is a serial study about mercury-containing lamps and electric arc furnace dusts. By reviewing and deciding on BACT last year, equipments for recycling experiment were established this year. The dates through the different operating conditions were identified and proposed suggestions to Taiwan’s EPA. The efficiency of treating SHPs, fluorescent lamp tailpipe, fluorescent tubes containing mercury/fluorescent-powder is higher than 99.9%, and CCFLs containing mercury/fluorescent-powder is higher than 80%, respectly. The low efficiency condition can be as a result of the complexity of the mercury compounds. Even at a temperature 700℃, mercury still can be vaporized constantly. This project suggest that mercury-contained lamps and amalgam should be separated before treatment. For municipal incinerator fly ashes, 1D ZnO rods with perfect crystal form and size of 80nm~2μm were successfully collected from EAFD treated with the carbon-thermal reduction process, and BaFe12O19 magnetic material was also synthesized from pre-treated EAFD in this study. The adjustments of dopants and sintering conditions are necessary in order to enhance the coercive field and remanent magnetization in the future. Since the prices of base-metals is continuing to be on the rise, the storage, usage and management of the by-products, such as Pb and Cd, from the purification of EAFD should be take into account. The project also makes the product regulations and resource recovery product quality standard of mercury and ZnO. Mercury purified at a level higher than 99.99% can be seen as a product. For municipal incinerator fly ashes, ZnO purified at a level higher than 55% can be seen as a product. | ||
