| titleOfInvention | Steel plant desulfurization wastewater resource zero-discharge process and system |
| abstract | The invention discloses a process and a system for realizing zero discharge of desulfurization wastewater resource in an iron and steel plant, wherein the process comprises the following steps: carrying out multi-effect forced circulation evaporation concentration treatment on the desulfurization wastewater of the steel plant under an acidic condition to obtain first concentrated water; and adjusting the first concentrated water to be alkaline, and carrying out atomization drying treatment on the alkaline first concentrated water by using high-temperature flue gas to obtain ammonia-containing mixed flue gas for resource utilization. The system comprises: the multi-effect evaporation unit is used for carrying out multi-effect forced circulation evaporation concentration treatment on the desulfurization wastewater of the iron and steel plant; the pH adjusting unit is used for adjusting the pH value of the first concentrated water output by the multi-effect evaporation unit; the bypass flue drying unit is used for carrying out atomization drying treatment on the first concentrated water after the pH value is adjusted; and the desulfurization and denitrification unit is used for providing high-temperature flue gas to the bypass flue drying unit and receiving the ammonia-containing mixed flue gas from the atomization drying treatment. The invention can effectively avoid system scaling, does not need to additionally increase equipment for removing ammonia nitrogen from the wastewater, and can effectively recycle the ammonia nitrogen in the wastewater. |
