膜电生物反应器（MEBR）是一项新技术，它通过在一个反应器中结合膜过滤、动电现象和生物过程来处理废水。本文针对难以生物降解的高浓度苯酚废水进行处理。研究了电催化工艺和膜生物反应器(MBR)中苯酚降解过程的初始浓度、电压、pH值、温度和混合液悬浮固体(MLSS)等影响因素，并在MEBR系统中应用了最佳条件。连续流实验的结果表明，与传统的 MBR 相比，MEBR 提高了处理后废水的质量。上述工艺遵循零级反应动力学。 MEBR 的苯酚去除效率比两个单独工艺的总和高约 11.1%。借助气相色谱/质谱 (GC-MS)，定性分析了 MEBR 中产生的苯酚降解产物，确定 2,6-二叔丁基对苯醌为主要降解产物。
The membrane electro-bioreactor (MEBR) is a novel technology, it treats wastewater by combining membrane filtration, electrokinetic phenomena, and biological processes in one reactor. This paper aims to deal with hard biodegradation and high concentration phenol wastewater. Investigating the influence factors such as initial concentration, voltage, pH value, temperature and mixed liquor suspended solids (MLSS) toward phenol degradation process in electrocatalytic process and membrane bioreactor (MBR), and then apply the optimum conditions in the MEBR system. Results of continuous flow experiments demonstrated that MEBR increased the quality of the treated wastewater than conventional MBR. The above technics followed the zero-order reaction kinetics. The removal efficiency of MEBR was about 11.1% higher for phenol than the sum of the two individual processes. With the help of gas chromatography/mass spectrometry (GC-MS), this qualitative analysis looks at the degradation products of phenol generated in MEBR, through which 2,6-di-tert-butyl-p-benzoquinone was confirmed as the main degradation product.
