摘　　要：本文针对煤化工废水膜浓缩液热法分盐结晶过程中,多种有机和无机组分浓缩富集影响相平衡,造成蒸发终点不易确定,硫酸钠和氯化钠品质不易控制的问题,以Na+、K+//Cl-、SO42--H2O多温度相图作指导,并开展相关实验,对蒸发终点的选取进行研究,用以指导工程实践。This article in view of the coal chemical industry waste water membrane concentrate hot points in the process of salt crystals,a variety of organic and inorganic components concentration enrichment affect the phase equilibrium,caused evaporation end point is not easy to determine,sodium sulfate and sodium chloride is not easy to control quality problems,with Na+,K+//Cl-,SO42--H2O temperature phase diagram for more guidance,and to carry out the relevant experiments,and studied the selection of evaporation in order to guide engineering practice.
