摘　　要：用三维电极法对山梨酸废水进行了降解实验,并考察电极材料、反应器电压、电解时间、进水pH值等因素对处理效果的影响。实验结果表明,以不锈钢作阳极,石墨作阴极,柱状活性炭作填料,在槽电压为20V、主电极极间距为11 cm的条件下,pH值为4.0±0.2的山梨酸废水在电解2030 min后,COD去除率达48%以上,而且废水的BOD/COD提高到0.40。The method of three-dimensional-electrode was used to study the pretreatment of sorbic acid wastewater. The operational parameters that affected the efficiencies of the wastewater treatment were discussed, including electrode material, applied voltage, pH value, electrolysis time, and so on. The experimental results showed that the removal ratio of COD reached to 48% and the BOD/COD increased to 0.40, when the voltage was 20 V, the working electrodes distance was 11 cm, the electrolysis time was 20 - 30 min, the pH value of wastewater was 4.0±0.2, under the condition of stainless steel as anode, graphite as cathode and cylindrical activated carbon as particle.
