摘要

新鲜水的工业除盐系统通常涉及膜分离（例如超滤、反渗透等），阴阳离子交换树脂床和储罐等。其中离子交换和膜分离单元可看作单入口双出口的半连续过程单元，具有间歇用水过程的特征。然而，尚未有关于除盐水系统的间歇水网络综合的研究报告。对除盐水系统中双出口半连续单元和水箱分别建立流量衡算、杂质质量衡算模型和储罐模型。根据不同工况下除盐水的需求量，利用GAMS软件平台对建立的数学模型进行求解，得出除盐水系统中每个储罐的容量和对应的新鲜水用量。进一步根据储罐最大容量需求，设计出满足不同工况条件下储罐容量。简化的工业案例研究验证了所提出模型的有效性。

Abstract

Industrial fresh water desalination systems normally involve membrane(

. ultrafiltration

reverse osmosis

etc

ion exchangers and storage tanks. Note that ion exchange and membrane separation processes can be operated semi-continuously and they can be considered as batch partitioning regeneration units with a single inlet and two outlet streams. However

there is limited research on the synthesis of batch water networks involving freshwater desalination. This work established flow rate balance and contaminant mass balance model for batch partitioning regeneration units and tanks in the desalinated water system. According to the different demand for desalinated water under different condition

the GAMS software platform is used to solve the mathematical model. The needed capacity of each storage tank and the fresh water usage in each condition are determined

via

solving the model. The capacity of the storage tank can be designed according to the maximum capacity requirement of each storage tank. Simplified industrial case studies validate the validity of the proposed model.
