中文摘要	本計畫為加強高級資源回收再利用技術之研發，第一年進行含汞燈管及煉鋼集塵灰等有害量大、國內缺乏技術及可提升再生產品附加價值之廢棄物資源化技術研究，建置資源化實驗設備；第二年再依實驗成果建立再生產品規範，以協助國內環保產業升級，減少對國外進口之仰賴。另藉由廢棄物資源化技術研究，降低廠內暫存及境外輸出處理之比例，提昇再利用之資源化技術水準及再生產品行銷競爭力，增進廢棄物再利用比率。本計畫第一年已完成訪視國內5 家製造含汞燈管業者、7 家使用含汞燈管業者及12 家產出煉鋼集塵灰之事業機構（包括一般碳鋼、不銹鋼及合金鋼，後者由於製程特殊所以列入訪視等），其訪視成果與詳見報告書所述。另本研究以國內既有高汞燈管處理業之MRT 系統為建置廢含汞燈管處理最佳資源化技術，規劃廢含汞燈管資源化實驗設備之建立，擬定廢含汞燈管資源化實驗之流程。規劃實驗設計分為兩部份，第一部份為冷陰極管之含汞螢光粉、日光燈之含汞螢光粉、日光燈排氣管及曝光燈與UV 含汞燈之收集與精煉，另一部份則為精汞純化試驗，透過上述試驗裝置完成評估最適國內廢含汞燈管之資源化再利用技術。同時完成評估最適國內煉鋼集塵灰之資源化再利用技術，本計畫評估目前國外相關處理煉鋼集塵灰技術，已彙整分析其處理方式之優缺點。整體而言，火法生產效率較高，設備占地面積較小；多數方法中的Zn、Pb 等重金屬去除完整，可充分滿足環保法規之要求；伴生的鐵碳資源可以得到充分回收；單元操作較少，對原料的成分變化不敏感，且操作穩定易於最佳化。因此，儘管火法處理具有設備投資較大的缺點，但綜合評估效益較佳。其中又以旋轉平爐技術屬造塊直接還原法為主要趨勢，可得到純度很高，富含鋅與鉛之粗氧化鋅，旋轉平爐產出之直接還原鐵尚可成為電弧爐或高爐的原料。又奈米氧化鋅價格亦高，用途更廣，本研究未來將利用Waelz Process 產出之粗氧化鋅及以濕法分離自集塵灰之鋅溶液，配合水熱合成法製備奈米氧化鋅，作為提升資源化附加價值方向。

摘要	The first year of this project was focusing on the investigating the advanced recycling technology of mercury-containing lamps and electric arc furnace dusts EAFD, which contain great deal of quantity and lack technologies and additional values. Subsequently, equipments for recycling experiments were established. The second year will be concentrating on set up the standard of reusing product based on the experimental results, in order to assist the environmental industries to upgrade their technology and reduce the foreign support. Also the purposes are to reduce the ratio of temporary storage in the factory and foreign country export treatment of the wastes, rising recycling level and reusing products competitiveness, and increase waste reusing percentages. The first year of the project has investigated five mercury-containing lamps manufacturers, seven mercury-containing lamps consumers, and twelve EAFD producers which contain general carbon steel, stainless steel, and alloy steel. The reports of these investigations were in the yearly report. The research was focusing on the understanding MRT system that is the leading waste mercury-containing lamps treatment technology in the world and planning the waste mercury-containing lamps recycling equipments. The design of equipment contains two parts, the first part includes the collecting and refining CCFL fluorescent powder, lamp fluorescent powder, lamp exhaust pipe, SHP, and UV mercury-containing lamps. The other part is the mercury purification experiment. According to the experiments results, the evaluation of the most suitable waste mercury-containing lamps recycling technology was accomplished. The EAFD recovery technique, which is most suitable for the industries and environmental conditions in Taiwan, were investigated. This research also analyzed the advantages and disadvantages of each commercialized EAFD treatment process. In conclusion, the pyro-metallurgical processes have the higher efficiency, the smaller needed plant area, the higher recovery efficiency of Zn, Pb and Cd which satisfy the demands of environmental regulations and codes, and the capability of recovering iron content. Furthermore, they have the advantages of fewer unit operations, non-sensitive to variation of EAFD composition and easy to handle. We prefer to recommend the pyro-metallurgical methods though they are expensive in the equipment investment. Among the pyro-metallurgical processes, the Rotary Hearth Furnace (RHF) using carbon-thermal reduction is best choice. The produced Direct Reduction Iron (DRI) can be recovered as the raw material for EAF or BF. Furthermore, the recovered ZnO has the higher purity and value. The ongoing study will focus on the purification of crude ZnO produced by Waels process and the synthesis of nano ZnO powder using the hydro-metallurgical processes combined with the other methods such as hydrothermal and precipitation processes.
