| Abstract: | Natural evaporation experiments of the distilled ammonia waste liquid from were carried out combined with local climatic conditions. The crystallization type, composition, crystallization order, water evaporation rate, salting-out rate and the relative evaporation coefficient at different stages were analyzed and calculated. The best separation point to separate calcium chloride and other beneficial components was determined by experiments, which could provide basic data for the engineering design of the solar pond evaporation process. |
