Abstract:	本研究主要以電化學方式產生氧化劑氧化降解分散性染料，探討電化學反應過程中之電流密度、導電度及pH 值、ORP變化與通電時間關係。實驗分別以直接和間接方式進行：直接法實驗將染料廢水混合電解質通電，間接法則是探討電解產生氧化劑，以量測個別方法對染料色度與濁度的氧化裂解效果，同時並探討在不同操作参數條件下，對氧化裂解的影響。研究結果顯示，利用電化學方式可確實產生氧化劑，而電壓越大、通電時間越久及電解質濃度越高，所能產生的氧化劑越多。間接法對分散性染料在短時間內無法起明顯效果，推測間接法需要時間讓染料和氧化劑接觸反應。直接法則有明顯的氧化去色效果，其中以增加電壓的貢獻更大。因間接法中染料溶液沒有直接接觸到極板，故可推論極板上應有相當的氧化效力，使直接法的氧化能力高於間接法。 This study is treatment of disperse dyes by Electrochemical oxidation process. The Parameters considered in the Electrochemical oxidation procedures include voltage, current, pH, ORP,addition sodium chloride concentration and reaction time. The experiment respectively carries on by the direct method and the indirect method. Indirect Electrochemical method can product the oxidation agent (OCl-). But it can''t efficiently decomposed organic disperse dye (DR-60). Direct Electrochemical oxidation method can rapidly decomposed disperse dye. Operating time 40 mins. And usefully raise voltage than addition sodium chloride concentration. I think that plate is the key.
