摘　　要：对反渗透海水淡化过程的设计进行了研究。首先对过程的每个单元给出了单元操作模型和相关的经济模型。通过一定的变量将这些模型相互关联,组成系统模型。系统模型主要考虑了一级流程和二级流程。将年费用最小定为目标函数,并满足过程热力学、设备选型、设计要求等约束。系统的设计问题可表达为一个混合整数非线性规划(MINLP)。当产品水的设计要求不同,给水浓度不同时,采用本文的设计方法分别得出了不同的最优设计方案。这个方法可用于海水、苦咸水淡化的工程设计,也可用于高浓度含盐废水的脱盐工艺设计。The design for sea water RO desalination process was studied to give out operational model and related economic model for each unit and carry out interconnection for these models with a certain variables,and then system model was formed. In the system model, the first-stage and second-stage technological processes are considered with the minimum annual expense as target function. The system model is required to meet the restriction of process thermodynamics, equipment type selection and design requirements etc. The system's design problem can be expressed as a mixed-integer non-linear programming(MINLP). When the requirements of product water design and feed water concentration are different, the different optimal design scheme can be derived from this design method. The method can be used for the design of sea water and brackish water desalination engineering.
