| dc.description.abstract | 彩色濾光片製程大量使用光阻染劑，所產生的色度廢水排放於承受水體往往造成民眾觀感不佳，添加次氯酸鈉(NaOCl)去除色度為業界較普及與經濟的處理方式，然而其衍生出的氯產物對生態環境及設備儀器的傷害也是去除色度這問題外必須格外重視的議題。
本研究是將光電產業界超純水製程中的離子交換樹脂在經由正常運作汰換下，評估再利用作廢水中氯離子去除之可行性。在離子交換樹脂實驗分析中發現，案例廠廢水處理過程所衍生出的氯離子在不同pH及SV等可變因子中，以設定參數pH 10與6 SV（Space velocity：流量CMH/樹脂填充量M3）時其氯離子去除效率最佳，故設定此為實驗中最佳操作條件，依據案例廠離子樹脂交換之最佳操作條件進而探討其對染色廢水中pH、導電度、餘氯值等去除效益相關性。藉由實驗結果數據分析了解，案例廠染色廢水經由離子樹脂交換處理後，其水中氯離子、導電度、pH、餘氯等皆能有效降低，減少對環境的衝擊，因此不論在水資源管理或產品生命週期角度考量上，在案例廠設置離子交換樹脂處理單元是有一定之必要性。 | zh_TW |
| dc.description.abstract | The color filter process uses a large amount of dyed photoresist and generate colored wastewater. Removal of color by sodium hypochlorite (NaOCl) is popular because of easy operation and low cost. However, the residual chlorine and by-product may affect the following treatment equipment, the effluent water quality, and the aquatic environment.
In this study, reuse of the ion exchange resin from the ultrapure water process of the photoelectric industry for the removal of residual chlorine and chloride in wastewater was evaluated. It was found that when the solution pH was 10 and the space velocity was 6, the removal of chloride is the most efficient. At the optimal operating conditions the solution pH, conductivity, and residual chlorine of the chlorinated wastewater was examined. The results showed that the conductivity and the residual chlorine were also effectively removed. This work shows that chlorination can effectively reduce the color in the photoresistant wastewater. The residual chlorine and chloride can be removed by ion exchange. Moreover, resin from ultrapure water process can be used in the removal of residual chlorine and chloride. Thus, the amount of wasted resin can be significantly reduced.
