| 摘 要： | 研究了活性炭纤维(ACF)作电极电化学处理染料废水的问题．考查了电极材料、电压、电解时间以及电解质等因素对电化学处理染料废水效果的影响．结果表明，以ACF作阴极，ACF 不锈钢作阳极，在电压为15V，电解时间为30min，电解质NaCl加入量为5kg/t的条件下，染料废水的色度去除率可达96．10％，COD去除率达56．78％．在电解后的废水中加入少量CaO可以解决返色问题．研究表明，ACF是一种新型的催化电极材料．

| Abstract: | Dyeing wastewater treatment with activated carbon fiber as an electrode were studied. The efects of electrode materials, voltage, electrolysis time and electrolyte on dyeing wastewater treatment with the electrochemical method were investigated. The result shows that the decolouring rate can reach above 96.1%, and the ratio of removing COD is 56.78% under the condition of ACF as a cathode, ACF stainless steel material as an anode, the-voltage was 15 V, the electrolysis time was 30 min, the amount of NaCl as electrolyte reached 5 kg/t. After electrolysis, adding a little of CaO in the wastewater can solve the problem of recolouring. It is proved that ACF is a type of catalyzing electrode material. |
