摘要
采用铁屑微电解处理含铬废水,探讨废水的pH、停留时间以及铁碳体积比等因素对处理效果的影响.结果表明,pH为5～6、V（Fe）∶V（C）为4∶1及停留t为30 min,经动态法处理的含铬废水,铬的去除率可达99.5％.以铁屑微电解法处理含铬废水,在技术和经济上都是可行的,以废治废的实用的水处理技术,具有工艺可靠、投资少、操作简便和运行费用低等优点.
This article reviewed the microelectrolytic treatment technology for chromium-containing wastewater. The influence of the reaction parameters such as pH, reaction time and the ratio of iron/carbon on treatment effect were studied. The wastewater removal ratio could reach to 99.5 % under the condition of pH 5 -6, iron/carbon ratio at 4：1 and reaction time 30 min. It is possible for chromium-containing wastewater to be disposed mainly by microelectrolytic method. This method has practical application with advantages of low cost in investment and operation.
