摘要： Algogenic organic matter (AOM) resulting from algal blooms in water can cause severe membrane fouling in water treatment. This paper investigated the performance of mesoporous and microporous carbon (CPAC) treatments on microfiltration (MF) membrane fouling behavior and mechanism of various AOMs. The results indicated that microporous activated carbon had limited effects on improving filtration flux, whereas the synthesis of mesoporous carbon (SOMC) exhibited a great ability to alleviate membrane fouling. When the SOMC was added in 100 mg/L doses, the filtration flux improved by 5%, 9.2%, 8.7%, and 33% for Aphanizomenon flos-aquae (APF), Anabaena flosaquae (ANF), Scenedesmus obliquus, and Cyclotella (Cy) AOM, respectively. The molecular weight distributions, organic hydrophobicity demonstrated that the SOMC mainly removed macromolecules of the neutral hydrophilic (N-HPI) and hydrophobic (HPO) organics, such as polysaccharides and protein-like organic matter, whereas the CPAC mainly adsorbed humic-like substances organics. Linear regression analyses suggested that the content of biopolymers content in the AOM were highly correlated to membrane fouling, whereas humic-like organics had minor effects on MF membrane fouling. Diatoms of Cy-AOM with lower macro molecular biopolymers and higher HPO fraction can be better treated than cyanobacteria of APF- and ANF-AOM by SOMC. The SOMC of mesoporous-rich activated carbon was suggested as an appropriate pretreatment method in AOM-involving water treatment during MF compared to microporous carbon.
