甘肃某水源地Cr^(6+)污染防治技术研究

The Prevention of Cr^(6+) Pollution at Miaoergou,Gansu Province

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.

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.
