| 英文摘要 | A novel electro-coagulation/oxidation membrane reactor (ECOMR), in which electrocoagulation (EC) and electrooxidation (EO) were integrated into one reactor with the membrane module placed in the electric field zone between the electrodes, was designed to create synergistic coagulation and oxidation effects for mitigation of ultrafiltration membrane fouling. The results showed that EO modulated the morphology of the cake layer by breaking up humic acid (HA) molecules (i.e., carboxylic functional groups and aromatic structures), giving a more porous cake layer, while EC increased the hydrophilicity of the formed cake layer, leading to the alleviation of membrane fouling. The cake layer formed in the ECOMR by combination of EC and EO under electric fields was more hydrophilic and more porous, resulting in a normalized water flux about 9.57% and 13.2% higher than the EC membrane reactor (ECMR) and EO membrane reactor (EOMR), respectively. Moreover, the cake layers formed in the ECOMR exhibited lower affinity for the membrane surface, which meant they were easier to clean off. These findings demonstrate that the ECOMR is a promising water treatment technology to alleviate membrane fouling as well as improve water quality. |
