摘　　要：该文给出了气田水电渗析浓缩液的组成及综合利用流程。按ＮａＣｌ2—ＫＣｌ—ＣａＣｌ２─Ｈ２Ｏ体系相图对制取氯化钠和氯化钾的工艺路线进行解析和计算。试验结果证明与相图计算结果是一致的，为制取氯化钠和氯化钾提供了合理的工艺流程。This paper gives the compasition of concentrated solution of waste water in gas field by electrodialysis and its comprehensive utilization circuit. Caculation and analysis according to the phasediagram of NaCl - KCl -- CaCl_2, - H_2O system were completed for the techological process ofmaking sodium chloride and potassium chloride. Experimental results proved to coinide with thecalulation results.
