摘要(Abstract)：

高盐有机废水若不能得到有效处理而被任意排放,将会造成环境污染和无机盐的浪费。在"双碳"背景下,高盐废水"零排放"和盐分的高值化再利用已成为该领域的研究重点。由于高盐废水中有机污染物的高效去除是实现脱盐水回用和废水中盐分资源化利用的前提,文中通过制备金属-有机框架(MOFs)衍生催化剂FeCo-C/N,探究FeCo-C/N+O₃催化氧化体系对NaCl质量浓度为310 g·L^-1、总有机碳(TOC)含量为20~60 mg·L^-1的高盐含酚废水处理效果,使得氧化后水样的TOC去除率达到65.1%~88.2%,废水中TOC残余含量均小于10 mg·L^-1,满足离子膜电解中对进槽盐水的品质要求。继续将氧化后的高盐废水进行离子膜电解试验,使阳极出槽淡盐水中NaCl质量浓度介于200.0~210.0 g·L^-1,阴极出槽盐水中NaOH质量分数介于32.0%~33.5%,电解过程进行336 h后的电流效率和吨碱电耗分别是96.8%和2 167.0 kW·h,表明处理后的高盐含酚废水在离子膜电解中运行稳定、经济合理,具备良好的资源化利用前景。研究结论能为高盐有机废水大规模应用于离子膜电解工业提供参考。
