Fenton程序擁有良好及迅速的去除能力，但其產生大量的污泥導致其很少被使用在實廠上。因此本研究將Fenton程序產生之污泥以電解法還原再生亞鐵離子，由實驗結果發現由鐵污泥再生之亞鐵離子，可成功成為Fenton程序所需之鐵源，而其電解還原亞鐵離子之最佳pH值為1。電解再生亞鐵離子之電流效率約為20～30%左右。
本研究以染料廢水作為原水，而且當 Fe(II)相對於總流量的比值超過0.03時，COD去除率就可達到90%以上。出流水的導電度由0.87～67.8 ms，隨著亞鐵離子的加藥量而增加。鐵污泥在經過多次的循環使用後，導致VSS/TSS大於30%，使得污泥脫水性不佳。
在研究中發現鐵污泥還原形成亞鐵離子可作為Fenton程序中之鐵源，並可以成功的處理人工染料廢水，以及減少污泥的產量。

Fenton process producing hydroxyl radical removes contaminants efficiently and rapidly. However, huge quantity of iron sludges produced by the process hinders application of this process in full scale treatment system. In this study, Fe (II) regenerated from iron sludge by electrolytic method was employed to reduce the sludge problem. At pH of 1.0, Fe (II) can be regenerated efficiently from iron sludge. The electrolytic current efficiency of Fe(II) regeneration was about 20~30%, depending on current density.
Synthetic dye wastewater was prepared and treated with Fenton process using regenerated Fe (II). More than 99% of COD removal can be achieved by the process. Effluent conductivities increased with increasing the dosage of regenerated Fe (II), ranging from 0.87 to 67.8. VSS/TSS ratio of sludges increases and dewaterability of iron sludge worsen gradually with the number of the sludge been used.
In this study, we found the sludge could be reuse and reduce to Fe(II) which was used as the iron source for the subsequent Fenton process. Synthetic dye wastewater was treated with Fenton process using recycled iron, and the amount of sludge generated was reduced substantially.
