Abstract: The electrolytic mangan wastewater was processed by iron chipping.The factors of iron chipping amount, reaction time and the influence of wastewater pH on the purgation ratio of Cr6+,Mn2+ were investigated. The results show that under usual temperature when amount of iron chipping is 15%, wastewater pH is 4.00, reaction time is 120 min, Cr6+,Mn2+ and total chromium purgation ratio were 99.7% and 99.2%.when it was used to practice the treatment electrolytic mangan wastewater, purgation ratio of Cr6+,Mn2+ was 99.45% and 95.53%.

Key words: iron chipping, microelectrolysis, wastewater
