AI Technical Summary
Existing technologies are insufficient to effectively treat and utilize waste sodium sulfate generated from industrial processes, leading to increased water salinity and environmental pollution. Furthermore, traditional treatment methods, such as converting it into sodium sulfate or landfilling, are impractical.
Waste sodium sulfate is converted into potassium sulfate and sodium carbonate by reacting with potassium carbonate. The crystalline potassium sulfate and sodium carbonate solution is then recovered using a low-temperature method, avoiding the use of chlorine-containing compounds and achieving zero-waste treatment.
This technology enables the efficient conversion of waste sodium sulfate into valuable chemicals, reduces environmental pollution, provides reusable industrial raw materials, and lowers processing costs.
