Title:: Treatment of Chromium-Containing Wastewater by Iron Chipping Microelectrolysis

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56、V(Fe)∶V(C)为4∶1及停留t为30min,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。

Abstract:: 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.
