摘　　要：研究了活性炭技术中生物量的变化及其对运行效果的影响。结果表明,活性炭性能和结构对生物量有重要影响;反冲洗后生物量损失高达90%;温度越高,生物量也越高;臭氧投加会降低生物量;生物量越高,对于UV254的去除率就越高,但是对嗅味和AOC的影响不明显。另外,生物量增加所导致的出水细菌增加要引起重视。The variation ofbiomass and its effect on effluent water quality in different BAC filters were studied. The results showed that the capability and structure of activated carbon have important effect on biomass. And aider backwashing, the loss ofbiomass was as high as 90%. With the tempera- ture rising, the higher the temperature, the more the biomass, However, the addition of ozone can decrease the biomass. The more the biomass, the high- er the removal ofUV254. However, the removal of taste and odor and AOC was not affected notably. More attention should be paid to that the increases ofbiomass would cause the more bacteria number in effluent.
