摘　　要：采用电解氧化法深度处理二段序批式生物膜反应器(SBBR)处理渗滤液生化出水。因SBBR出水水质波动大,利用响应面法(RSM)设计电解氧化试验,求出COD去除率模型并进行优化分析。结果表明,以COD去除率达到85%～95%的目标,当COD为1 400～1 850 mg.L-1时,选择电解时间2～2.5 h或外加Cl-的质量浓度为0～2 000 mg.L-1可达到目标;当COD为1 850～2 300 mg.L-1时,选择电解时间2～2.5 h或外加Cl-的质量浓度为0～2 000 mg.L-1可达到目标。从节约电耗、节约药剂量(外加Cl-的量)和电解效果3方面进行分析,从而实现去除效果和经济成本有效平衡。Using electrolytic oxidation advanced treated the biological effluent water that the two steps SBBR dispose the mature landfill leachate.Due to the biological water quality were large fluctuations,using response surface methodology to design experiment of electrolytic oxidation,obtaining the COD removal efficiency model and optimization the test results.The results showed that,required the COD removal was 85%～95%,when the COD concentration was 1 400～1 850 mg·L-1,selecting the electrolysis time of 2～2.5 h or external Cl-concentration of 0～2 000 mg·L-1 to achieve the target;when the COD concentration was 1 850～2 300 mg·L-1,selecting the electrolysis time of 2.5～4 h or external Cl-concentration of 2 000～4 000 mg·L-1 to achieve the target.From the conservation of power consumption,saving dosage（plus Cl-）,and electrolysis effect were analyzed,in order to achieve the cost-effective removal and economic balance.
