| 摘 要： | 采用电催化氧化技术(electrocatalysistechnology)在电解槽中直接生成羟基自由基与Fe(OH)3絮凝剂,并对酚类、磺酸类及染整工业废水进行了降解研究。研究表明,电生成Fenton技术在处理还原型工业废水中均有很好的降解效果。对邻苯二酚和间苯三酚均有较高的电流效率,对间苯二酚和间苯三酚的CODCr去除率达80%以上;对十二烷基苯磺酸钠CODCr的去除率达到85%;对茜素红等染料的脱色率达100%,CODCr的去除率达到70%。

| Abstract: | An electrocatalytic oxidation technology was used for direct formation of hydroxyl free radicals and Fe(OH)3 flocculant in the electrolytic cell, and the degradation of the wastewater from phenol, sulfonic acid and textile dyeing and finishing industries was studied. It was shown by the study that the technology of electric formation of Fenton reagent resulted in good degradation in the treatment of reductive industrial wastewater. When this technology was used, the current efficiency with pyrocatechol and phloroglucinol was higher, the removal rates of resorcin and phloroglucinol exceeded 80%, the removal rate of the CODcr of sodium dodecyl benzene sulfonate (SDBS) reached 85%, the decolorization rate of Alizarine Red and other dyestuff reached 100%, and the CODcr removal rate reached 70%. |
