摘要
硫酸生产过程中会产生大量酸性含 Hg、As、F的废水。用石灰乳对硫酸生产废水进行预处理 ,不仅可中和废酸 ,还可以沉淀除去其中大部分的 Hg、As、F。在第二阶段处理中 ,联合使用Na2 S、泥浆。
The watewater with mercury, arsenic and fluorine is produced in great quantities in the process of sulphuric acid production. Lime cream as a pretreatment means can not only neutralize the waste acid, but also precipitate the majority of mercury, arsenic and fluorine in the wastewater from sulphuric acid production. In the second stage, the wastewater from sulpharic acid production can meet the national discharge standards by jointly using Na 2S, slurry and alum.
