摘要
介绍了反渗透浓缩液再利用的方法,综述了这些方法的原理、特点及应用,重点讨论了脱除反渗透浓缩液过饱和度进行回用以提高系统回收率的方法,以及膜蒸馏技术对浓缩液的回用处理、废水浓缩液处理及海水淡化浓缩液制盐,指出了反渗透浓缩液再利用在经济和环境上的必要性。
The methods for reusing reverse osmosis （RO） concentrates are introduced. The principles, characteristics and application are summarized. The paper focuses on the removal of supersaturation of RO concentrates to get high water recovery, membrane distillation technique to recovery RO concentrates, disposal of wastewater RO concentrates and production of salts from seawater RO concentrates. Considerable economic and environmental benefits could be achieved by reusing of RO concentrates.
