| titleOfInvention | Treatment of magnesium sulfate wastewater |
| abstract | (57) [Summary] [Problem] To recover magnesium hydroxide from wastewater containing a large amount of magnesium sulfate, which is discarded and discharged in a flue gas desulfurization plant using magnesium hydroxide as a desulfurizing agent, and together with the treated liquid Establish technology to recycle to flue gas desulfurization process to contribute to recycling and environmental purification. SOLUTION: Ammonia is added to a flue gas desulfurization wastewater containing magnesium sulfate to form and precipitate magnesium hydroxide, and then lime milk is added to the liquid to form calcium sulfate and an mower, and ammonia is circulated in the process. The obtained magnesium hydroxide is slurried with the final effluent of this process and circulated to the desulfurization plant, thereby achieving complete circulation of the desulfurization plant effluent. Eliminate the release. In addition, calcium sulfate was provided with a washing step to improve the purity and the advantage of external sales. |
