A comprehensive utilization and treatment method and equipment system for ammonia distillation wastewater from the ammonia-soda process includes an evaporation and concentration chamber, a heat pump system, a cooling chamber, a freezing separation chamber, a heat exchanger, an evaporation and crystallization chamber, and a cooling crystallization chamber. Combined with solar radiation, the wastewater undergoes a multi-stage heat exchange cycle through evaporation, cooling and freezing separation, gas-liquid separation, evaporation and crystallization, and cooling crystallization. This process effectively and continuously separates sodium chloride and calcium chloride salts while recovering fresh water. The sodium chloride recovery rate is 75%, the calcium chloride recovery rate is 75%, and the fresh water recovery rate is 55%. This reduces the input cost of raw salt and the amount of mixed solids landfilled in the alkali production process, lowering operating costs. The wastewater can be directly used as lime slurry or, after treatment, as raw water for molten salt, conserving water resources. Through the comprehensive utilization of the wastewater, evaporation efficiency is increased, land area previously occupied by solar pond evaporation of the wastewater is reduced, and the comprehensive utilization of waste resources is maximized.
