摘　　要：以TiO2-蒽醌改性双极膜中间层,并用作电解槽隔膜降解含酚废水.通过测定降解过程中苯酚溶液的紫外-可见分光光度和高效液相色谱,研究改性双极膜对苯酚降解的影响.电镜扫描、膜阻抗测定、渗透性测定等结果表明,TiO2-蒽醌改性双极膜在提高膜性能,降低膜阻抗,减少能源消耗等方面效果良好,紫外光照射180 min,苯酚降解为CO2和H2O.Industrial waste water containing phenol was difficultly degraded by the bacteria treatment.Photocatalytic degradation of phenolic wastewater has been paid more and more attention presently.TiO2-anthraquinone was used to modify the intermediate layer of a bipolar membrane（BPM）,which was equiped in a cell for electro-catalytic degradation of the phenolic wastewater.The TiO2anthraquinone modified BPM was investigated by SEM,electrochemical workstation and OH^-permeability.The degradation process of phenol solution was measured by UVvisible spectrophotometry and high performance liquid chromatography.The degradation mechanism was discussed.Experimental results showed that the modified BPM enhanced membrane performance,reduced membrane resistance and the energy consumption.In conditions of UV irradiation for 180 min,phenol was degraded to CO2 and H2O.
