摘　　要：针对含铬废渣对环境污染大及治理难的特点,提出了以废渣治理废渣的技术,利用鼓风炉渣的还原性以及刚排出时的高温,将铬渣按一定比例与之混合,进行铬渣的解毒处理,并对铬渣的解毒机理进行了理论分析。从实验结果可以看出,当铬渣加入量低于10%时,该技术能够较彻底的将铬渣中的Cr6+进行解毒。A technique using the waste slag to treat chromium dregs has been advanced in order to eliminate environmental pollution.Using the high temperature and reduction of the blast furnace slag,the chromium dregs were mixed at appropriate proportion with blast furnace slag, which could make chromium dregs detoxify.In the present study,the detoxification mechanism of chromium dregs was analyzed theoretically.The experiment results show that the blast furnace slag can remove the toxic of Cr~ 6+ completely while the mass quantity of added chromium dregs was less than 10 percent.
