Method for decomposing sodium aluminate solution

The invention relates to a decomposition method of sodium aluminate solution, and is characterized in that the sodium aluminate solution is processed by ultrasonic irradiation when the solution is decomposed. Compared with the existing chemical method, the prior art of alumina production is not changed in the invention, which has little investment in devices and little energy consumption and environment protection. The ultrasonic technology is introduced into Bayer process to for alumina production technique, which leads the technique to be simple, highly practical and effectively enhances the decomposition rate of seed and the product granularity of aluminum hydroxide. The crystal seed decomposition of the sodium aluminate solution is effectively strengthened, and the time for decomposition is shortened, while the decomposition rate is enhanced and the granularity distribution of the product is improved with good effect.
