摘要
用废铁屑为原料对电解锰生产废水进行处理 ,考察了铁屑用量、反应时间和废水pH值对Cr6+ ,Mn2 + 去除率的影响 .实验结果表明 ,在铁屑用量为 15 % ,废水pH值为 4 ,常温下反应 12 0min的条件下 ,Cr6+ ,Mn2 + 的去除率在 99.7%以上 ,总铬去除率达 99.2 % .同时 ,将实验结果用于工厂废水处理运行 ,效果良好 ,Cr6+ 的去除率为 99.4 5 % ,Mn2 + 的去除率为95 .5 3% .
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 Cr 6+ ,Mn 2+ 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, Cr 6+ ,Mn 2+ 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 Cr 6+ ,Mn 2+ was 99.45% and 95.53%.
