中文摘要 | 台灣地區預計在民國九十四年前興建完成二十一座垃圾焚化廠,屆時每年將產生約 150萬噸之焚化灰渣。這些焚化灰渣中含有過量之戴奧辛及重金屬,若未加以妥善處理則會造成嚴重的二次污染。本研究採用電漿高溫熔融技術,將有害之焚化灰渣(反應灰與集塵灰)進行玻璃化處理,並將水淬之玻璃質熔渣進行一階段熱處理以形成微晶材料。研究結果顯示,在1150℃熱處理所得的微晶材料有較佳之物理及機械性質。微晶材料經XRD分析後發現其主要礦物相為透輝石(Diopside)及鈣鋁黃長石(Gehlenite)。此微晶材料具透水性,未來可發展為透水磚以達到環保及廢棄物資源化之目的。 |
英文摘要 | There are 21 municipal waste incinerators under construction in Taiwan that are expected to be completed at the end of 2003. It is estimated that these incinerators will produce over two million tons of incinerated ashes every year. However, these incinerated ash contains large amount of hazardous materials such as Dioxins and heavy metals. If these hazardous materials cannot be carefully treated, it will cause detrimental secondary contamination. This research work adopted a plasma melting technology to treat incinerated ashes and produced microcrystalline materials. It was found that the main mineral phases were diopside and gehlenite. Microcrystalline materials produced at 1150℃ have the best physical and mechanical properties. These microcrystalline materials with good quality have great potential to serve as water permeable brick for construction applications. |
