中文摘要	鉛蓄電池具有高電量、高安全性、高穩定性、低成本等優點，其大量應用於車用電瓶、電動堆高機等電動機具和不斷電系統等。金聯成資源科技股份有限公司(以下簡稱本公司)為應回收廢棄物-廢鉛蓄電池處理機構，將廢鉛蓄電池中的鉛電極及塑膠外殼進行拆解回收再利用。目前鉛蓄電池的回收製程中，需使用大量的清洗水，並且排放出鉛含量約2 mg/L至20 mg/L的廢水需化學混凝法將鉛沉澱去除，過程中需添加液鹼、金屬捕捉劑等化學品並產生含鉛污泥；鉛污泥不但無法再利用，處理費用更日趨高漲。因此，進行鉛蓄電池回收製程之製程水減廢，及水資源循環再生成為本公司重要的課題。本公司在搜尋製程改善技術時，發現工研院的玻璃奈米孔洞吸附材料吸附系統，對鉛離子具備良好的吸附能力，吸附後的材料可脫附並重複使用，預計可應用於本公司的鉛製程水，故提案本計畫，進行鉛蓄電池回收製程水循環處理系統建置，並進行系統性的測試評估。目前已完成的含鉛製程水循環處理系統，可將水中的鉛離子以吸附的方式去除，水中的鉛離子濃度可降到1 mg/L以下，效果十分顯著，且能大幅減少液鹼的使用量，處理後的水亦可導回製程循環使用，大幅降低本公司用水量，同時亦完成經濟效益評估，確認技術可行性。

摘要	Lead-acid battery possesses the advantages of high capacity, safety, stability and low cost. A large number of lead-acid batteries are applied in mobile battery, electrical forklift or other electrical machines and industrial uninterruptible power supply, etc. Materials of spent lead-acid battery are recycled in the lead-acid battery recycle industry. The spent lead-acid battery is divided into lead and plastics in the physical decomposition process. A large amount of water is used to wash the decomposed parts in the process. However, the processed water, containing 2 mg/L to 20 mg/L lead, can’t be reused. The lead in the processed water also can’t be recovered, too. As the result, the alkali and the metal gathering chemicals are added to remove lead from processed water traditionally. Treated water with lead concentration below the effluent control scale is discharged. The waste lead becomes heveay metal sludge. The sludge, which is the secondary pollutant, is not able to be reused and the treatment cost gets higher and higher. Therefore, the reduction of processed water waste and the recycling of water resources in the lead-acid battery’s recycling process have become an important issue for our company. By searching the heavy metal water treatment technology and the related literatures, we found out that the LCD glass adsorbent from the colaberation research of EPA and ITRI exhibits exellent adsorption behavior of lead metal ions. The material can be applied on the innovative heavy metal processed water treatment technology that is different from the traditional chemical coagulation method. We expect to use this technology to deal with the lead-containing processed water in the lead-acid battery recycling process of our company. In addition to reusing the processed water, which the lead metal ions are removed, in our decomposition process, the lead materials obtained through the saturated absorbent desorption process will be evaluated to produce lead ingot products in our smelting process. In this project, the construction of water cycle treatment system for lead-acid battery recycling process using the LCD glass nano porous absorbent is proposed. A systematic evaluation process is also proposed for the follow purpose: (1) Recycle water resource from lead-containing processed water through the adsorption system. (2) Recover lead resource from the processed absorbent. (3) Decrease the alkali usage. (4) Decrease the heveay metal sludge. We expect that based on this project, we can evaluate and promote the green cycle and resource regeneration of the lead-acid battery recycling process. We believe that this application will make the development of lead-acid battery recycling industry more environmentally friendly.

摘要

Lead-acid battery possesses the advantages of high capacity, safety, stability and low cost. A large number of lead-acid batteries are applied in mobile battery, electrical forklift or other electrical machines and industrial uninterruptible power supply, etc. Materials of spent lead-acid battery are recycled in the lead-acid battery recycle industry. The spent lead-acid battery is divided into lead and plastics in the physical decomposition process. A large amount of water is used to wash the decomposed parts in the process. However, the processed water, containing 2 mg/L to 20 mg/L lead, can’t be reused. The lead in the processed water also can’t be recovered, too. As the result, the alkali and the metal gathering chemicals are added to remove lead from processed water traditionally. Treated water with lead concentration below the effluent control scale is discharged. The waste lead becomes heveay metal sludge. The sludge, which is the secondary pollutant, is not able to be reused and the treatment cost gets higher and higher. Therefore, the reduction of processed water waste and the recycling of water resources in the lead-acid battery’s recycling process have become an important issue for our company. By searching the heavy metal water treatment technology and the related literatures, we found out that the LCD glass adsorbent from the colaberation research of EPA and ITRI exhibits exellent adsorption behavior of lead metal ions. The material can be applied on the innovative heavy metal processed water treatment technology that is different from the traditional chemical coagulation method. We expect to use this technology to deal with the lead-containing processed water in the lead-acid battery recycling process of our company. In addition to reusing the processed water, which the lead metal ions are removed, in our decomposition process, the lead materials obtained through the saturated absorbent desorption process will be evaluated to produce lead ingot products in our smelting process. In this project, the construction of water cycle treatment system for lead-acid battery recycling process using the LCD glass nano porous absorbent is proposed.
