The water samples collected from the world were analyzed by SEC（size exclusion chromatography）、EEM（excitation-emission matrix）and some basic analysis. We hoped to generalize relation between the characterization and its source by this analysis. The results showed that the DOC and SEC-UV254 area had similar removal efficienccy in all samples. It represented that the composition of DOM must be similar no matter where the water sample came from There are still many residual DOM in the drinking water today. In order to test the estrogen potential of raw water and treatment water , we use ELISA（Enzyme-Linked ImmunoSorbent Assay） to analyze. The results showed that the raw water of T-C and T-B WTP（Water Treatment Plant）reached 50% inhibition ratio after concentrating 21300 and 10800 times. The clean water of T-C and T-B WTP reached 50% inhibition ratio after concentrating 53100 and 32900 times. The treatment process can removal parts of estrogen potential. Different operation processes and coagulant dosage were tested for improving the removal efficiency of DOM. It had better removal efficiency by higher dosage of coagulant and higher strength of mixing. The maximum SEC-UV254 removal is 56.5% by coagulant. It meat that coagulation process just can removal part of the DOM. Powdered activated carbon（PAC） was used to improve the removal of the dissolved organic matter. All the powdered activated carbon added in the raw water was effective in removing the dissolved organic matter in except for 1000-2000 Da molecule. The SEC-UV254 removal reached to 80% in 15 minutes by dosing 150（mgL-1 as C）PAC. It suggested that PAC adsorption was more efficient to remove DOM than coagulation process.致謝 I要 IIBSTRACT III錄 IV目錄 XI一章 前言 1二章 理論基礎與文獻回顧 2 2-1 國內外相關淨水處理程序之研究 2 2-2 水中天然有機物組成與分析 4 2-2-1 分子大小排斥層析法 4 2-2-2 螢光分析 5 2-2-3 內分泌干擾素 6三章 實驗設備與內容 8 3-1 實驗水樣介紹 8 3-2 實驗藥品 10 3-3 實驗設備 11 3-4 實驗方法與流程 13 3-4-1 濃縮 13 3-4-2 雌激素潛勢測試 - 酵素免疫分析法 14 3-4-3 原水溶解態有機物分子量分級 15 3-4-4 含砷腐植酸水樣之雌激素潛勢 16 3-4-5 探討操作程序對原水溶解態有機物之移除率16 3-4-6 以活性碳吸附原水中溶解態有機物 17 3-5 水樣分析方法 18 3-5-1 高壓分子大小排斥層析法(HP-SEC) 18 3-5-2 三維螢光激發-散射光譜（EEM） 19 3-5-3 溶解態總有機碳分析（DOC） 20 3-5-4 界達電位分析 21 3-5-5 濁度分析 21四章 實驗結果與討論 22 4-1 世界及台灣各地原水與清水分析 22 4-1-1 基本性質分析 22 4-1-2 各國水廠之處理效率比較 32 4-1-3 各國水樣DOC與其濁度、SEC線下面積及三鹵甲烷含量之討論 36 4-2 雌激素潛勢 39 4-2-1 T-C與T-B淨水廠雌激素潛勢 39 4-2-2 原水溶解態有機物分子量分級並測試其雌激素潛勢 49 4-2-3 J國原水濃縮粉末雌激素測試 52 4-2-4 含砷腐植酸水樣之雌激素潛勢 54 4-3 探討操作程序對原水溶解態有機物之移除率 57 4-3-1 以PACl移除原水中溶解態有機物 57 4-3-2 以程序配合三種混凝劑移除水中溶解態有機物 64 4-4 以活性碳吸附原水中溶解態有機物 79五章 結論與建議 86考文獻 8732621292 bytesapplication/pdfen-US溶解態有機物雌激素潛勢混凝活性碳dissolved organic matterestrogen potentialcoagulationactivated carbon[SDGs]SDG6thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/186908/1/ntu-97-R95524074-1.pdf
