中文摘要：

成功制备了活性碳纤维负载的纳米铁电极（Fe／ACF），并通过SEM、EDS进行了电极表征．某小区生活污水基于该电极的阴极E-Fenton氧化处理结果表明，在电压1．2V、中性条件下处理2h，初始COD由200mg／L，降低到70mg／L，COD去除率达到65％，出水水质达到国家排放标准GB8978-2000中的一级标准．

英文摘要：

In this study, a novel electrode was successfully prepared by loading nanostructural iron on the surface of activated carbon fiber （Fe/ACF）. Scanning electron microscopy （SEM） and engery dispersive X-ray spectroscopy （EDX） were used to characterize the as-prepared composites. It was found that 65% COD removal of municipal sewage was reached in the presence of 1.2 V potential between the anode and the cathode based on the eletro-Fenton reaction using a nanoscale Fe/CNTs as a cathode at a neutral pH value, and the effluent quality is up to the first grade of National Standard GB8978-2000.
