摘　　要：再生水回用是缓解水资源短缺的重要途径。针对再生水制备,提出磁性阴离子交换树脂耦合电吸附的新工艺,对比了磁性树脂工艺、电吸附工艺和耦合工艺脱盐和有机物去除上的性能,同时分析了耦合工艺的优势。实验结果表明,耦合工艺的脱盐效率达92.3%,COD去除效率达45.9%,出水能够满足再生水水质标准。技术耦合既增加了电吸附技术的脱盐能力和磁性树脂吸附技术的有机物去除能力,又保护了电吸附电极、延长使用寿命,是一种极具潜力的高效再生水制备工艺。The utilization of reclaimed water is one of the most important way to alleviate the shortage of water resources. The magnetic resin adsorption coupled with capacitive deionization technology was proposed for the preparation of reclaimed water. The desalination and organic matters removal performances of magnetic resins adsorption, capacitive deionization technology, and the coupling technology were compared. It was found that the desalination efficient of the coupling technology was 92.3% and the COD removal rate was 45.9%. The effluent of the coupling technology met the quality standard of reclaimed water. The coupling technology not only enhanced the desalination and organic matters removal performances, but also decreased the fouling of electrode by dissolved organic matter. The magnetic resin adsorption coupled with capacitive deionization technology was proved a potential efficient preparation method for reclaimed water.
