Fenton程序兼具OH‧氧化及鐵鹽混凝雙重功能去除有機物，本研究探討Fenton相關程序過氧化氫分解與有機物礦化之影響。以紅色反應性偶氮染料Evercion Red H-E3B與聚乙烯醇(Poly(vinyl alcohol)，PVA)配置染料20 mg/L、PVA 50 mg/L之人工染整廢水，其色度與DOC濃度分別為1200單位與30 mg/L。以鐵鹽加藥量、pH、氧化時間及H2O2加藥量為操作變數，分析殘留之H2O2、色度及DOC。所有實驗採批次式瓶杯試驗。
　　研究結果顯示Fenton程序去除色度與DOC效率為pH3＞pH4＞pH2.5。pH 2.5、pH 3、pH 4於低Fe2+加藥量下便可得到良好脫色效果，且脫色皆以氧化機制為主，增加Fe2+加藥量僅改變氧化及混凝脫色之比例；然而Fe2+加藥量對DOC之去除影響較顯著，增加Fe2+加藥量可提升DOC之去除率，並且提升混凝去除機制所佔之比例，其為增加Fe2+加藥量可生成較多之Fe3+增加混凝效果。　　
　　H2O2加藥量對脫色與DOC去除之研究，H2O2於25 mg/L時便可有效脫色，增加H2O2加藥量僅影響對DOC去除率，亦可提高氧化去除DOC及氧化脫色之比例，但超過H2O2最適加藥量，反而將使得氧化機制之比例下降，其為過量之H2O2與有機物競爭OH‧，使得用於氧化有機物之OH‧減少，相對造成混凝機制去除有機物之比例增加。氧化時間為5分鐘時色度與DOC之去除率即達穩定，且增加氧化時間對去除率差異不大。

The Fenton process is one of the advanced oxidation processes (AOPs) which eliminates organic matter by both hydroxyl radical (OH‧) oxidation and iron salts coagulation. The study was to evaluate the effects of the decomposition of hydrogen peroxide and the mineralization of organics by conducting Fenton-related process. A reactive azo dyestuff (Evecion Red H-E3B, 20 mg/L) and polyvinyl alcohol (PVA, 50 mg/L) were used to simulate color and dissolved organic carbon (DOC) in the industrial textile wastewater which consisted of color of 1200 ADMI unit and DOC of 30 mg/L. The dosages of iron salt, pH, oxidation time as well as dosage of hydrogen peroxide (H2O2) were applied as the operational variables. The capability of the treatment was evaluated by measuring the residual of H2O2 , color unit and DOC. All the experiments were in-beaker tested.
The results indicate that the ability to remove color and DOC in Fenton process is at the pH in the order of pH3> pH4> pH2.5. The color removal efficiency works well in pH 2.5, pH 3 and pH 4 under the circumstance of low iron salt dosage. The major mechanism to remove color is oxidation. The dosage of iron salt makes no significant difference in color removal and merely changes the ratio in color removal either by oxidation or coagulation. The iron dosage, however, greatly influences the DOC removal efficiency. Increasing iron salt (Fe2+) dosage enhances greatly on DOC and also improves the coagulation process due to the production of Fe3+ in the treatment. 
The initial concentration of H2O2 plays a vital role in the oxidation of organic compounds in Fenton process. The optimal dosage of H2O2 is 25 mg/L for color removal as of the oxidation effect. Instead, the excessive amount of H2O2 does not increase the DOC removal since DOC removal is only performed best at some optimum dosage while excessive H2O2 will compete OH‧ with organic matter which retards the oxidation of the organic matter.  The oxidation time of 5 minutes reaches the stable status for color and DOC removal, which excessive time period will make no difference.
