中文摘要 過去研究針對染整廢水常以AOPs(Advanced Oxidation Processes , AOPs)程序中之Fenton法處理,然而Fenton法卻有污泥之後續處理問題。本研究以強氧化劑過硫酸鈉(Sodium persulfate, Na2S2O8)配合一般染整業排放廢水皆較高溫的特質,並結合UV光照射催化產生硫酸根自由基來降解染整業廢水色度。期待了解過硫酸鈉於不同溫度及配合UV光照射之染料去除效果與其限制,以及染料orange II降解之反應機制,如反應動力常數、半衰期、活化能等。
實驗設計為過硫酸鈉分別在溫度20、40及60℃熱催化並結合UV光照射降解染料,以及在 NaPS/Dye = 15、7.5及1.5下,探討過硫酸鈉對偶氮染料orange II色度之去除狀況及氧化劑之使用量。
Orange II染料降解在本實驗條件中為擬一階動力反應,Orange II染料僅經由熱能並無法將其降解,當加入熱催化後過硫酸鈉鹽方可對色度行降解。且染料降解效率亦隨溫度上升而增加;此外,氧化劑量的增加(NaPS/Dye莫耳比增加)對染料降解效率亦可提昇,而降解速度也隨溫度提昇及NaPS/Dye莫耳比增加而增加。在60℃及NaPS/Dye =15條件下,有UV活化能為77.38KJ/mole,而無UV光照射下120.84 KJ/mole。
相較於使用Fenton方法,本實驗方法實可以減少二次汙染問題,而再結合UV光照射輔助降解染料證實UV可以降低活化能而有效增加色度降解。
英文摘要 The past researchers investigating dyeing wastewater focused mainly on Fenton which is one of Advanced Oxidation Processes (AOPs). However, Fenton has the problem of generating large quantity of waste sludge. Taking the advantage of higher temperature in dyeing wastewater, in this study sodium persulfate (Na2S2O8) was thermally activated with or without UV radiation to produce sulfate radical for decolorization of dyeing wastewater. The aim of this work is to investigate the effects of temperature and Na2S2O8 dosges on decolorization of dye by thermally activated Na2S2O8 with or without UV radiation. Reaction kinetic parameters of dye orange II decolorization process such as pseudo-first-order reaction rate constant, half-life and activation energy are calculated.
The decolorization of orange II azo dye with thermal activation of Na2S2O8with or without UV radiation are investigated at temperature of 20oC, 40oC, and 60oCand NaPS/Dye molar ratio of 15, 7.5, and 1.5. The decolorization of orange II follows the pseudo-first-order reaction rate kinetic. Increased Na2S2O8 dosges and temperature enhance the efficiency of decolorization. Under the condition of NaPS/Dye =15, the activation energy with UV radiation is 77.38KJ/mole; in the meanwhile, the activation energy without UV radiation is 120.84 KJ/mole.
In contrast to Fenton, thermally activated Na2S2O8 can alleviate the problems of generating secondary waste sludge. Furthermore, the concepts that UV could decrease activation energy and increase the effectiveness of decolorization are supported by experimental results.
