摘　　要：采用三维电极固定床技术对焦化废水进行了深度处理的实验研究,并取得了相应的工艺参数。实验研究结果表明,三维电极技术能有效的处理焦化废水,在槽电压为12V,液体催化剂量为1500mg/L,反应时间为60min,pH为3,COD去除率可达62%。Three-dimension fixed-bed electrode technology is a new method for advanced treatment of coking wastewater, especially effective for handling refractory organic pollutants. This paper reports on some experiments using a bench-scale apparatus, including an electrolytic trough, within which graphite anode and cathode are fixed, granulated activated carbon and quartz sand packed; some liquid catalyst containing Fe2+ is applied for promoting Fenton reaction.
