廢面板玻璃改質玻璃奈米孔洞吸附材料於重金屬廢水吸附系統應用研究與實廠化驗證
| 中文摘要 | 隨著全球經濟的發展，各種工業活動造成的環境汙染日益嚴重，如土壤或水源受重金屬汙染，特別是一些發展中的國家。由於重金屬對環境及生物體具危害性，亦會透過食物鏈損害人體的健康。然而目前用以處理土壤或廢水中重金屬的技術都有些缺點與限制，例如處理成本過高、處理程序複雜、或是會產生二次汙染及基質干擾等問題。因此，目前亟需一個簡單、便宜且高效率的重金屬廢水處理技術。 玻璃奈米孔洞吸附材料是先進且創新之重金屬吸附材料，使用廢棄液晶面板玻璃做為原料，在高硬度玻璃中創造奈米孔洞結構，將其轉換為一種具獨特性且高效率之重金屬吸附材料，可有效吸附廢水中的重金屬離子。此材料具有高耐酸及耐化、低成本、高重金屬吸附能力、無需前處理等特性，而被吸附之重金屬可脫附再使用，更重要的是吸附材料本身亦可重複再生使用。因為此材料於吸附過程中不會產生二次污染，可直接應用於工業廢水中重金屬離子之吸附處理，再加上其本身乃使用廢棄物所製造的一種新型材料，同時兼具環保與材料高值應用的特性。本研究主要針對玻璃奈米孔洞吸附材料建構一套日產量200公斤的試量產系統且在應用方面亦建構一套重金屬廢水處理系統，並以此系統處理含銅量平均為15毫克/公升的廢水10.8公噸、含鉻量平均為1,400毫克/公升的廢水900公升，處理後的水均可達到放流水標準。 | ||

Technology validation of removal of heavy metals from electroplating wastewater using the green glass adsorbent transformed from waste LCD panel glass.
| 英文摘要 | With the development of the global economy, environmental pollutions which are caused by industrial activities have gradually increased, such as soils and water polluted with heavy metals, resulting in the deterioration of the environment, especially in some developing countries. Because heavy metals are extremely hazardous to the environment and organisms, they harm to human wellness through the food chain. However, there are some problems or limitations in the current treatments of wastewaters and soils contained heavy metals, such as high treatment cost, complicate pretreatment, secondary pollution, matrix consideration etc. To create a simpler, cheaper, and efficient needed no limitation in use approach for wastewater treatment is urgently necessary. Green glass adsorbent is a novel type of heavy metal adsorbent with high efficiency. It is transformed from waste LCD panel glass with an specific nano-technology. It features some specific characteristics, including: high adsorption capacity; excellent acidic and chemical resistance; recyclable; pretreatment before adsorption is unnecessary; no secondary pollution generates after the adsorption process and adsorbed metal ions can be simply desorbed and recycled. Applying the green glass adsorbent to treat wastewaters is simple, in which the green glass adsorbent is added directly into wastewater to adsorb heavy metal without pretreatment and it is easy to be regenerated for reuse. Compare to other adsorbent or ion exchange resin, no matter the production cost or the operation cost, the green glass adsorbent possess great advantages to increase custom’s wilingness to use. In this study, we scale up the production of the green glass adsorbent to 200 Kg per day. Furthermore we also design an on-line modularized adsorption system for heavy metals in wastewater. At present, 10.8 tons of wastewater containing 15 mg/L of copper and 900 litters of wastewater containing 1,400 mg/L of chromium have been treated. Both of them can conform the effluent standards promulgated by EPA | ||
