采用膜法淡化苦咸水流程和设备的集成化

为了解决缺水地区水资源问题 ,通过对微滤、超滤和反渗透 3种膜过程作用的分析 ,提出一种集成化膜法水处理工艺方案 ,并设计、制造出一套集成化设备。应用该设备对 3种不同含盐量的苦咸水进行脱盐实验。讨论了集成化膜法水处理装置设计的关键问题 ;测定了系统运行过程中有关的参数。实验结果表明 :水处理系统的脱盐率大于 96 % ,回收率不小于 6 5 % ;淡化水水质达到国家标准规定的指标要求。该工艺集成化程度高 ,无需配置中转箱、泵 ;自动化程度高 ,可为大规模水处理工程提供设计参数。

Integrated Membrane Process and Related Equipment for Brackish Water Treatment

To develop more efficient technologies to treat brackish water so that it can be used in daily-life and industries, an integrated membrane process was presented and tested. The process consisted of microfiltration, ultrafiltration and reverse osmosis processes, with a capability of water treatment of 500?L/h. All units in the process were controlled by a PLC system, while the on-line cleaning of the ultrafilter was realized by using an energy reservoir. The desalination tests with the brackish water of different saline contents show that the desalination efficiency and the water recovery can attain to 96% and 65%, respectively, and the desalinated water meets quite well the requirement of the national standard of China for drinking water.
