The Fe/C micro-electrolysis and Fenton combined process was used to solve the high yield organic CLT acid wastewater in our country. The influence factors of pH, reaction time, ratio of iron and coke, H₂O₂ dosage and reaction time of H₂O₂ were investigated. The results show that when the influent COD is 28.1 g/L to 34.5 g/L, pH is 2.5, ratio of iron and coke is 2∶1 and the reaction time is 60 min, the removal rate of COD by ferric-carbon micro-electrolysis is above 30％. For treatment with the Fenton when the H₂O₂ (30％) dosage is 0.15 mol/L, the reaction time is 60 min and the temperature is 20 to 30 ℃, the removal rate of COD reaches more than 43％, B/C ratio of wastewater increases from 0.08 to 0.43.
