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1.2 V、中性条件下处理2 h,初始COD由200 mg/L降低到70 mg/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.
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.
