摘　　要：目的研究电极材料在三维电极-电Fenton处理制药废水过程中对COD去除率的影响,找寻最佳工艺条件。方法以模拟阿奇霉素制药废水为处理对象,分析在相同控制条件下以阳极材料、活性炭粒子电极类型、浓度对制药废水中COD去除效果的影响,并确定最佳试验条件。结果综合成本考虑,三维电极-电Fenton体系处理制药废水以石墨为阴极材料,以钛涂钌铱作为阳极材料,柱炭粒径为3 mm、投加量为100 g/L时处理效果最好,COD去除率达到77.39%,可生化性由0.072提高至0.353。结论阳极材料、粒子电极的粒径、浓度对于三维电极-电Fenton体系处理制药废水的降解效果具有较大影响;研究结果可以满足后续生物处理要求。The effect of electrode materials on COD removal rate from pharmaceutical wastewater by three-dimensional electrode-electrical Fenton and the optimal process conditions were studied.Simulated azithromycin pharmaceutical wastewater taken as the raw water,the effect of anode materials,activated carbon particle type,and concentration on the COD removal effect from simulated wastewater under the same control conditions was analyzed,and the optimal process conditions were determined.Results showed that based on the comprehensive cost,in the process system graphite taken as the cathode material,titanium-coated ruthenium-iridium as the anode material,and the 3 mm particle size of activated carbon with a dosage of 100 g/L the treatment effect was best with removal of COD reached 77.39%and the biochemistry increased from 0.072 to 0.353.The anode material,particle size of the particle electrode,and concentration had great influence on the degradation effect of the three-dimensional electrode-electric Fenton system for treating pharmaceutical wastewater;the results of the study can meet the requirements of subsequent biological treatment.
