Description
技术领域 technical field

背景技术 Background technique
目前，普通的曝气生物滤池虽然对有毒有害，难降解有机物有一定的去除率，但是单独采用曝气生物滤池对于成分复杂的有毒有害难降解有机物去除效果较低，污水中尚有的有毒有物质对于环境也有一定的影响。而三维电极是一种高级氧化方法，其对于难降解有毒污染物去除效果较好，但是在三维电极反应中会产生引起电流效率降低的副反应如析氧、析氢、产热、析氯等。本专利将复极性三维电极和曝气生物滤池有效的组合在一起，以提高城市污水中有毒难降解有机物的去除效果。 At present, although the common aerated biological filter has a certain removal rate for toxic, harmful and refractory organic matter, but the single use of the aerated biological filter has a low effect on the removal of toxic, harmful and refractory organic matter with complex components. Toxic substances also have a certain impact on the environment. The three-dimensional electrode is an advanced oxidation method, which has a better effect on the removal of refractory toxic pollutants, but in the three-dimensional electrode reaction, side reactions such as oxygen evolution, hydrogen evolution, heat generation, and chlorine evolution will occur, which cause the current efficiency to decrease. This patent effectively combines the bipolar three-dimensional electrode and the biological aerated filter to improve the removal effect of toxic and refractory organic matter in urban sewage.
