TECHNICAL FIELD

[0002] In industrial production, especially in the power and chemical industries, a desulfurization process is a key link for controlling sulfur dioxide emission, and a large amount of desulfurization wastewater is generated in the desulfurization process. The desulfurization wastewater contains high-concentration suspended solids, heavy metals, sulfates and the like, and has complex components and high pollutant concentration. At present, in the treatment method of the desulfurization wastewater, a chemical precipitation method is one of the most widely used technologies due to simple operation and low initial investment, and the core principle of the chemical precipitation method is to synchronously convert heavy metal ions and calcium and magnesium ions in the wastewater into solid-phase particles by one-time addition of composite reagents such as lime, sodium carbonate and sodium sulfide, and then to realize solid-liquid separation through flocculation and precipitation.
