| titleOfInvention | A kind of method of anthraquinone waste sulfuric acid oxidation treatment to produce polyferric sulfate |
| abstract | The invention discloses a method for producing polymeric ferric sulfate by oxidizing waste anthraquinone sulfuric acid. The method steps are as follows: under the condition of divalent iron ions, reacting waste anthraquinone sulfuric acid with hydrogen peroxide, and oxidizing organic impurities in the waste sulfuric acid, The purified sulfuric acid is then reacted with the steel oxide skin to adjust the acidity of the material, filtered and oxidized to obtain a polymerized ferric sulfate product. The present invention optimizes the existing Fenton oxidation treatment technology, the method has the characteristics of simple process, low cost, high COD removal rate and removal efficiency; and uses purified acid to produce polyferric sulfate water purifying agent, and realizes waste treatment and waste resources with waste. The purpose of comprehensive utilization, and at the same time, it has good environmental and economic benefits, and it is easy to realize industrial production. |
