Abstract
电催化氧化是处理废水中新兴微污染物的一种极具吸引力的选择,然而,平面电极有限的反应表面积和短的使用寿命阻碍了它们的工业应用。本研究介绍了一种创新的电化学废水处理技术,该技术采用静电纺催化膜(MBR)作为动态电催化过滤器,并被稳定在阳极板上同时作为电流收集器,电活性面积从普通平面阳极扩展到具有巨大电催化表面积的MBR多层介质。由于电活性MBR层不与阳极板绑定,因此可以随时更换。选择典型的抗生素污染物四环素(TC)作为模型微污染物进行实验研究。MBR过滤器在20 min的单次过滤时间内实现了对TC近80%的降解,降解率比传统电化学氧化工艺高一个数量级以上。带电荷的MBR过滤器对TC降解效率明显高于传统的电催化阳极系统。电活性MBR层与基钛阳极之间的分离使得电极材料的更新和系统的实际应用变得容易。从根本上提高了电化学氧化工艺在废水处理和回用中的适用性并降低了成本效益。这项技术有可能彻底改变电化学废水处理,并为未来水环境治理的可持续发展做出贡献。
