摘　　要：以钛涂铱钌(Ti/RuO2-IrO2)平板为阳极、石墨板为阴极,采用电化学氧化法对土霉素废水二级处理出水进行了深度处理试验研究。确定了最佳电解条件:电流密度为0.10A/cm2、极板间距为2cm、电解质(Na2SO4)浓度为0.3mol/L和不调整废水pH值,在进水ρ(COD)=264.32mg/L时,电解60min后出水ρ(COD)<120.00mg/L,COD去除率可达60%以上。在最佳电解条件下,COD去除动力学方程为ln(c0/ct)=0.012 9t-0.001 7,其相关系数R2=0.997 5,近似符合一级动力学方程。Electrochemical oxidation of secondary effluent of oxytetracycline wastewater is investigated using Ti/RuO2-IrO2 plate as anode and graphite plate as cathode, respectively. The results show that when current density is 0. 10 A/cm2 , elec trodes span is 2 cm, concentration of electrolyte （Na2 SO4 ） is 0.3 mol/L and the initial pH of the wastewater isn＇t adjusted, the 264.32 mg/L of COD concentration of the inffluent electrochemical is reduced below 120.00 mg/L after being oxidized for 60 min. The COD removal rate is over 60%. The electrochemical oxidation degradation process of COD is approximate complied with the first-order kinetics equation： In（C0/C1） = 0. 012 9t-0. 001 7 （R2 =0. 997 5）.
