摘要
以海水淡化膜集成系统的构建为核心,分析反渗透海水淡化的优势和存在的问题;综合评价膜法预处理-反渗透、反渗透-正渗透、反渗透-压力延迟渗透等几种典型的膜法集成系统;提出利用膜法集成技术进一步降低海水淡化能耗与实现零排放的基本思路与原理.同时,详细介绍海水淡化膜法集成系统在海水淡化过程中海水预处理、盐差发电、浓盐水再利用等方面的具体应用进展,为低能耗零排放的海水淡化膜集成系统的构建提供指导与借鉴.
This review aims to update the recent progress of developing the integrated membrane systems for seawater desalination, including the seawater pretreatment-RO system, the RO-forward osmosis (FO) system and the RO-pressure retarded osmosis (PRO). Furthermore, the energy consumption of the integrated membrane systems was analyzed to show their advantages in the power generation from the comprehensive brine utilization and seawater pretreatment. Finally, new insights for the development of integrated membrane systems were pointed out for future work.
