Application of Micro Electrolysis and Fenton Reagent for Industrial Waste

We discussed the effects of pH value, reaction time and the dosage of carbon、iron、hydrogen peroxideand sodium hydroxide on the removal rate of COD though micro electrolysis and Fenton reagent method. The resultsshowed that the removal rate of chromaticity was above 98% only in Fenton process, it was lower than 5. When the pHvalue of micro electrolysis was controlled at 4.0, there was a great deal of white crystal separated out, and it was easilyfiltrated, so its application value was very high. The conclusion of this article was that the optimal conditions of thisexperiment were the pH value was 4.0, the ratio of iron and carbon was 0.6, the reaction time was 12 hours, and theCOD from 21860 mg/L dropped to 4558 mg/L, its removal rate was 79.2%.
