摘　　要：为充分发挥臭氧氧化和陶瓷超滤膜过滤的协同作用,将臭氧和陶瓷超滤膜集成在同一构筑物中,构建了臭氧/陶瓷超滤膜短流程工艺,系统地研究了该工艺的净水效能和膜污染情况。结果表明,单独陶瓷超滤膜过滤对浊度和微生物的去除效果显著,出水浊度稳定在0.10 NTU以下且未检测到微生物,但对磺胺甲噻二唑、磺胺甲基异口恶唑和磺胺二甲嘧啶等磺胺类抗生素的去除能力有限;臭氧/陶瓷超滤膜短流程工艺显著提升了对UV_(254)和磺胺类抗生素的去除效能,降低了出水SUVA值和类蛋白质、类腐殖酸及类富里酸等荧光有机物的含量,但增加了出水DOC含量;臭氧的投加有效地提升了陶瓷超滤膜通量,缓解了可逆和不可逆污染,其中可逆污染阻力的缓解对减轻膜污染起主要作用,这为臭氧/陶瓷超滤膜短流程净水工艺的推广应用提供了技术支撑。In order to make full use of the synergistic effect between ozonation and filtration by ce- ramic uhrafihration membrane, ozone and ceramic uhrafihration membrane were integrated in the same u- nit, and an ozonation/ceramic uhrafihration membrane short process was built. The performances of water purification and membrane fouling were systematically studied. The results showed that fihration alone by ceramic uhrafihration membrane had excellent removal effect of turbidity and microorganisms, with efflu- ent turbidity less than 0.10 NTU, and no microorganism being detected, whereas the removal effieieneies of sulfonamide antibiotics including sulfamethizole, sulfamethoxazole and sulfamethazine were limited. Ozonation/eeramic uhrafihration membrane short process could significantly improve the removal rates of UV254 and sulfonamide antibiotics, increase effluent DOC, and decrease effluent SUVA and fluorescent organic matter including protein-like, humic acid-like and fulvic acid-like substances. Ozonation could effectively improve the flux of ceramic uhrafiltration membrane and mitigate both reversible and irreversi- ble fouling. The mitigation of reversible fouling played the leading role for membrane fouling control. This can provide technical support for the popularization and application of ozonation/ceramic uhrafihrationmembrane short process for water purification.
