摘　　要：通过正交实验法、单因素实验、连续实验等方法,验证微电解-Fenton氧化联用处理高盐难降解废水的可行性及探索最佳运行参数。结果表明微电解-Fenton氧化可以高效去除高盐废水COD,微电解最佳运行参数为p H值3,气水比15∶1,反应时间(HRT)120 min,固液比1∶1,Fenton反应最佳运行参数为H_2O_2浓度3.5‰,反应时间(HRT)90 min,该工艺对COD整体去除率达到90%以上,处理后的废水可生化性大大提高。本工艺实验进水含盐量高,具有适应高盐度废水和快速分解COD的特点。Through the orthogonal experiment method, the single factor experiment, continuous experiment, this paper vali-dates the feasibility of treating high salt refractory wastewater with micro electrolysis-Fenton oxidation and the best operation pa-rameters. Results show that the micro electrolysis - Fenton oxidation can be efficient in removing the COD from high salt wastewater. The micro electrolysis optimal operation parameters are pH 3, 15：1 gas water ratio, reaction time（HRT） 120 min, solid-liquid ratio 1：1, Fenton reaction optimal operation parameters for H2O2 concentration 3. 5‰, the reaction time（HRT） 90 min. The experimental water has high salt concentration, so the process is also applicable to the treatment of high salinity wastewater and rapid COD decomposition.
