| titleOfInvention | The treatment process of analysis |
| abstract | The present invention is the treatment process about a kind of analysis, and waste liquid described in it is containing Crn 6+ , Crn 3+ , Fen 3+ , wherein said method comprises the steps: step one, adds acid-base modifier and regulates waste liquid pH value to be 2 ~ 4, then add reductive agent, make Cr in waste liquidn 6+ be converted into Crn 3+ ; Step 2, the solution ph added after acid-base modifier adjustment reduction reaction is 10 ~ 12, makes the Fe in solutionn 3+ be converted into Fe (OH)n 3 coagulating sedimentation is separated out; Step 3, adds acid-base modifier and regulates the rear solution ph of precipitation to be 6 ~ 9, make the Cr in solutionn 3+ be converted into Cr (OH)n 3 precipitation.The treatment process of analysis of the present invention, makes the heavy metal in waste liquid be effectively separated. |
