摘要
以铁屑和纯Fe0为供试介质处理地下水中Cr6+,在不调节原水pH值情况下,通过室内对比试验发现铁屑比纯Fe0的去除效率高,且可使处理后水中Cr6+达到地下水质量标准的Ⅲ类标准,确定出铁屑去除Cr6+的最佳运行参数:铁屑与Cr6+的重量比为1395∶1,反应时间为40 m in,并分析讨论了其去除机理。
The iron chippings and pure Fe^0 are used as experimental mediators to treat groundwater containing Cr^6. The results indicate that the disposing efficiency of iron chippings is more than that of the pure Fe^0 through the parallel experiments in the room without adjusting pH of the groundwater. And the Cr^6 concentration of the disposed groundwater is up to the Ⅲ grade of the groundwater quality standard. The best operational parameter of disposing for Cr^6 is confirmed through the experiments, the weight radio of the iron chippings and Cr^6 is 1395: 1, and the reaction time is 40 minutes. The removal mechanism is analyzed in this paper.
