以广州市某电子有限公司络合铜废水为处理对象，采用Fenton氧化法强化处理经内电解预处理的出水，以达到进一步降低COD的效果。首先采用了单因素实验确定Fenton氧化的最佳[H2O2]／[COD]、[Fe2＋]／[H2O2]、初始pH和反应时间等条件。并通过中试实验考察了内电解与Fenton混合运行以及串联运行时的处理效果。单因素实验结论为，最佳[H2O2]／[COD]为2．0，[Fe2＋]／[H2O2]为0．2～0．3，pH为2．0～4．0，反应时间为60min。中试实验结果表明，串联运行的处理效果较好，其COD去除率为87．04％，铜的最终去除率达到99．86％。

The research takes copper wastewater pretreated by micro electrolysis in a Guangzhou electron company as the processing object, using the Fenton oxidation process to strengthen the treatment of wastewater, and then achieve further reduce of COD. The single factor experiment has been used to determine the optimal Fenton oxidation of [ H2O2 ]/[ COD ], [ Fe2＋ ]/ [ H2O2 ], initial pH and the reaction time. The pilot test has as well as been used to investigate the effect of the micro electrolysis and Fenton mix-processing and time series operation processing. Single factor experiments concluded that the best [ H2O2 ]/[ COD] is 2. 0, the best [Fe2＋ ]/[H2O2] is 0. 2 -0. 3, the optimal pH is 2.0 -4. 0, and the best reaction time is 60 min. In pilot experiment, the effect of treatment in the series run is better, The elimination rate of COD is 87. 04%, and the total copper＇s elimination rate achieves 99. 86%.
