摘　　要：采用臭氧化—生物活性炭 (O3/BAC)深度处理工艺去除水中消毒副产物前质的试验结果表明 ,该工艺能够有效去除水中消毒副产物前质 ,可控制氯化消毒副产物的生成 ,其中主臭氧化对三卤甲烷前质和卤乙酸前质均具有很好的去除效果 ,生物活性炭对卤乙酸前质表现出较好的去除效果 ,但对三卤甲烷前质的去除效果有限 ;藻类、有机物等在滤层的累积使得砂滤池在同一工作周期中的不同阶段对水中三卤甲烷前质的去除效果有所不同 ,因而需要合理设置砂滤池的反冲洗周期。臭氧化—生物活性炭工艺充分发挥了臭氧化和生物活性炭两种技术的优点 ,并相互促进和补充 。Experiment was made on the use of ozonation - biological activated carbon (O_3/BAC) treatment process for removing disinfection byproduct precursors from water. The result indicated that the process is able to remove effectively disinfection byproduct precursors from water and control the generation of chlorine disinfection byproducts. Of which, ozonation has good effect on removal of precursors of trihalomethane and haloacetic acid; biological activated carbon shows better effect on removal of haloacetic acid and limited effect on removal of trihalomethane precursor. Accumulation of algae and organic matters on filter layer results in various removal rate of trihalomethane precursor at different time of the same working cycle, so that it is necessary to rationally set the backwash cycle of sand filter. Ozonation - BAC process has given full play into the role of the advantages of the two processes and is able to provide full guarantee for safety of drinking water.
