| Abstract: | The process for removing the chromium from the silicon steel plant wastewaters was studied by using sodium sulfite as reducer. The results showed that both hexavalent chromium and total chromium in the effluent were able to meet with the requirements of the national discharge standard, when the solution PH value ranges were 2~3 and 8~8.5, respectively, in the reaction and precipitation stage, 1.4 times theoretical amount of sodium sulfite, reaction time 20min and precipitation time 2h. At the same time an important resource (Cr 2O 3) was prepared. |
