    Abstract: 本研究以PVA漿料500mg/L與反應性染料R94H 100mg/L之混合液,配製COD 1023mg/L(TOC 415mg/L)人工染 整廢水,採瓶杯試驗探討鐵鹽與雙氧水之加藥 量及氧化時間等操作變數對Fenton法氧化染整廢 水中難分解性有機物動力學之影響。Fenton法氧 化反應最適pH範圍為2-5,亞鐵催化能力較三價鐵 強。以COD為有機物指標時,由於雙氧水1mg/L產生 0.49mg/L COD,故需考慮殘留雙氧水對殘留COD之影 響;而以TOC為有機物指標時,則雙氧水不產生TOC。COD或TOC去除動力為一階反應,氧化速率常數 k/sub 1/或k/sub 2/(l/hr)隨亞鐵或雙氧水加藥量增 加而增大,氧化速率常數與雙氧水、亞鐵莫耳 濃度之關係分別為k/sub 1/=43045〔Fe/sup +2/〕 /sup 1.24/〔H/sub 2/O/sub 2/〕/ sup 1.12/或k/sub 2/=1033 〔Fe/sup +2/〕/sup 0.84/〔H/sub 2/O/sub 2/〕/sup 1.25/ 。
