摘要：Apparatus and methods are related to treating waste water containing

ammonium salts, which contains NH, SO, Cl, and Na. In such a method, the pH value of thewaste water to be treated is adjusted to a specific range in advance; sodium sulfatecrystal and relatively concentrated ammonia are obtained by first evaporation, and thensodium chloride crystal and relatively dilute ammonia is obtained by second evaporation;alternatively, sodium chloride crystal and relatively concentrated ammonia is obtained bythird evaporation, and then sodium sulfate crystal and relatively dilute ammonia areobtained by fourth evaporation. Ammonia, sodium sulfate, and sodium chloride from thewaste water are recovered so that the resources in the waste water can be reused.
