摘要
探讨了硫酸法钛白生产中的废硫酸治理。采用一次浓缩和化学方法将２０ ％ 废硫酸制备相关的化工产品；采用石灰中和法治理１ ％ 废硫酸，达到较为理想的治理效果。
The treatment of waste sulfuric acid in the production of sulfate process titanium dioxide was investigated. The 20% waste sulfuric acid is concentrated by one step, then chemically modified to produce relative chemicals. The residual 1% sulfuric acid is neutralized by lime to reach satisfactory results.
