膜生物反应器（MBR）工艺最近才应用于水处理。在此过程中，使用生物培养物和吸收剂（如活性炭）去除溶解物种，并使用微滤或超滤膜在系统内完全保留悬浮固体，包括生物质。MBR工艺已成功应用于二级废水处理、去除水中的芳烃、处理垃圾渗滤液和饮用水脱氮。使用臭氧作为预氧化剂已被证明是控制消毒副产物的有效策略。 几项研究表明，臭氧预氧化后再进行生物过滤是控制三卤甲烷和卤乙酸生成的有效策略，此外还能产生生物稳定的水。本研究的目的是优化MBR工艺，以去除预分区水源水中的可生物降解有机物，包括臭氧氧化副产物和三卤甲烷前体，同时最小化生物和颗粒膜污染。包括11个参考文献、表格、图表。

The membrane-bioreactor (MBR) process has only recently been appliedfor water treatment. In this process, a biological culture and an absorbent such as activated carbon, are used for removing dissolved species, and a microfiltration or ultrafiltration membrane is utilized to completely retain suspended solids, including biomass, within the system. The MBR process has been successfully applied for secondary wastewater treatment, removing aromatic hydrocarbons from water, treating landfill leachate, and drinking water denitrification. Using ozone as a preoxidant has been shown to be an effective strategy for controllingdisinfection byproducts. Several studies have shown that ozone preoxidation followed by biological filtration is an effective strategy for controlling trihalomethane and haloacetic acid formation in addition to producing biologically stable water. The objective of this study was to optimize the MBR process for removing biodegradable organic matter including ozonation byproducts and trihalomethane precursors from a preozonated source water while minimizing biological and particulate membrane fouling.
