电催化氧化预处理技术减轻超滤膜污染实验研究

Experimental Study on Electro-Oxidation Pretreatment to Reduce Ultrafiltration Membrane Fouling

  • 摘要: 实验探究电催化氧化预处理技术对膜污染的影响。实验通过电催化氧化工艺过程中产生的强氧化剂羟基自由基(·OH)无选择地与纤维素、腐殖质等难降解的大分子有机物反应,将其降解为小分子有机物,以此减缓膜污染。实验发现,通过使用电催化氧化工艺作为预处理方式处理二沉池出水,当电极为二氧化铅电极,电流密度为20mA/cm2,反应停留时间为3h时的处理效率为最佳条件,此条件下可以有效地减轻膜污染。
    Abstract: The experiment explored the effects of electrocatalytic oxidation pretreatment on membrane fouling. During the electrocatalytic oxidation process, the hydroxyl radical (·OH) was generated and the macromolecular organic matters such as cellulose, humus-like which are difficult to be degraded were degraded into small molecular organic substances by hydroxyl radicals, resulting in alleviating the Membrane fouling. The experiment shows that the electro-oxidation pretreatment has a better treatment effect in reducing membrane fouling. When the electrode was PbO2 electrode, the current density was 20 mA/m2, and the treatment efficiency was the best when the reaction residence time was 3 h. Under these conditions, membrane fouling can be effectively alleviated.
