The results indicate that with the increase of concentration ratio, the pH of desulfurization wastewater is decreased rapidly and then is gradually stabilized at 2–3 when SO2 or SO3 is contained in flue gas, and the increase in conductivity is less for wastewater with higher SO42− content. The reduction of wet desulfurization …

1. Introduction. Flue gas desulfurized gypsum mainly comes from thermal power plants, smelters, and large-enterprise boilers, and contains industrial by-products produced through a wet desulfurization combustion process, where SO 2 gas and lime slurry react under strong oxidation conditions. The main component of this gypsum is …
