| 中文摘要 |
| 以活性炭纤维作为新型电极材料,在15-25V的电解电压下对几种还原、酸性、活性、硫化等商品染料的模拟废水进行处理,色度去除率接近100%,COD去除率在30%-80%;通过红外、紫外、荧光、TOC等各种表征手段,初步研究了反应机理:处理过程可能主要是自由基反应的过程,同时伴随着絮凝的作用。在被电极吸附的情况下,自由基反应可以使染料分子通过偶合作用变大,从而易于被絮凝除去。 |
| 英文摘要 |
| In this article,a new type of electrode made of ACF to treat several simulated dye waste water was studied. Under the electrolytic voltage ranged from 15V to 25V,all the wastewater's chromaticity removals are near 100%,with COD removals within 30%-80%.And the reaction mechanism were figure out preliminarily by various characterization means such as IR、UV、spectrofluorimetry and TOC.Mainly,it may be that the treating processes involve radical reaction and coagulation simultaneously.The radical reaction can combine several organic molecules by radical coupling,so the larger molecule can be coagulated easily. |
