| titleOfInvention | GYPSUM PRODUCTION METHOD USING DE-SOx DUST TREATED WITH NaHCO3 |
| abstract | The present invention comprises the steps of preparing an aqueous solution of desulfurization dust by mixing desulfurization dust and water; And adding an aqueous calcium chloride solution to the aqueous solution of desulfurization dust to react. According to the present invention, the desulfurization dust generated during the desulfurization treatment in the sodium bicarbonate is more environmentally friendly than the wastewater treatment or landfill treatment method after simple dissolution, and thus, it is possible to avoid environmental problems caused by soil contamination or elution of heavy metals. In addition, since the gypsum manufactured according to the present invention has various types of use and can be used in various fields, desulfurization dust generated during desulfurization treatment with sodium bicarbonate can be stably, continuously, and converted into a large amount of resources. |
