| Abstract: | The absorption treatment of laboratory simulation chromium-containing wastewater by active coal gangue is researched.The result show that the removal rate of Cr can be above 90% with conditions: the concentration of chromium wastewater 100 mg/L,ratio of chromium and active coal gangue 5 mg/3.0 g,pH=10 and the contacting time 4h;the absorption accords with Freundlich absorption isotherms,the absorption isotherms equation is logq=0.778 0+0.971 6logc and it mainly relies on physical absorption. |
