摘　　要：开展了O_(3)-混凝沉淀-O_(3)/BAC-陶瓷膜联合工艺中试,探究了联合工艺对于长荡湖水处理效果及不同工况条件对跨膜压差的影响。结果表明,该工艺出水浊度可控制在0.1NTU以下,对COD_(Mn)、DOC和UV_(254)的去除率分别为73%、57%和70%,对荧光物质的去除率为67%~80%,高温季节应注意生物污染。阐明了膜污染机理与进程,为开发处理高浊度、高有机物地表水的陶瓷膜联合工艺提供参考。The pilot test of"O_(3)-coagulation-precipitation-O_(3)/BAC-ceramic membrane"combined process was carried out.The effect of combined process on the water treatment of Changdang Lake and influence of different working conditions on transmembrane pressure difference was explored.The results show that turbidity of effluent can be controlled below O.1 NTU.The removal rates of COD_(Mn),DOC and UV254 are 73%,57%and 70%.The removal rates of fluorescent substances are 67%~80%.Biological fouling should be paid attention to in high temperature season.The mechanism and process of membrane fouling were clarified.The reference for development of ceramic membrane combined process for treatment of surface water with high turbidity and high organic matter was provided.
