Abstract:	廢鋁熔煉的集塵飛灰多以一般事業廢棄物直接進行掩埋處理，然而因熔煉過程鋁與氮氣或聯胺產生高達3%的氮化鋁，遇水產生極臭的氨氣及硫化氫等臭味，造成掩埋場周遭居民抗爭。因此，本計畫擬針對廢鋁冶煉製程所產生的飛灰，藉由利用高解析熱電子型場發射掃描式電子顯微鏡的驗證蚓糞為綠色奈米級材料的生物製劑，並建立其基本的物理化學特性。藉助此奈米級的生物製劑處理廢鋁飛灰所衍生之廢氣惡臭，解決集塵灰遇水所產生的惡臭的NH3及H2S，更擴大應用乾蚓糞的除臭能力與推廣回收再利用、取代工業活性碳製作的減碳概念，達成永續經營。 Fly ashes produced from waste aluminum remelting process of the secondary aluminum smelter (secondary ALS) were usually disposed by delivering into the landfill directly. However, the fly ashes contained a large amount of AlN (~ 3%) that formed by Al reacting with N2 gas or N2H4 (hydrazine) and would release NH3 and other unknown odors when AlN reacts with H2O. In the project, we apply the high-resolution thermal field emission scanning electron microscopy to evidence the vermicomposting as one kind of nanoscale bioproduct and the high resolution surface area and porosimetry analyser to estimate the basic physical and chemical properties of vermicomposting. Furthermore, we employ the vermicomposting to removal 95% of NH3 and H2S in the fly ashes, achieving the ability of rapid deodorization and resulting in the legal disposal in the landfill. Therefore, it is a goal that extending the green product apply in the field of industrial odor and waste gas.
