| 摘 要： | 以甘肃省某水源地Cr6＋污染为研究对象,重点研究了该水源地供水区域以及周边地区饮水中Cr6＋含量水平和超标程度.在不调节pH的条件下,采用FeSO4还原法治理含铬水源水.结果表明：该方法合理可行、简便经济,适宜治理当地Cr6＋污染,且当Fe2＋/Cr6＋为22∶1,反应时间为20min时,除铬效果最佳,且处理后水质不会出现铁超标现象.

| Abstract: | In order to prevent the pollution of Cr6+ in drinking water,we took Miaoergou as the watersource,studied the quantitude of Cr6+ in and around the place and confirmed its polluted state.Without the adjustment of pH,we treated Cr6+ water by using FeSO4.Experiments showed that this method was easy,effective,and economical for the treatment of Cr in drinking water at Miaoergou. |
