| Abstract: | The concentration technologies of waste acid in titanium dioxide production by sulfuric acid method at home and broad are introduced and evaluated. The problems in treatment of waste acid in China are analyzed in the three aspects of process,equipment and material. The solutions are proposed for reducing or eliminating waste acid generation：optimizing the process condition；making sulfur reaction complete；perfecting the supporting facilities and improving the equipment quality；comprehensive considering the proportion of waste acid,new acid and ilmenit；mating choice of better anti-corrosion composite materials for manufacture equipment. |
