| 摘 要： | 探讨了臭氧对于污水生物处理中活性污泥特性的影响。结果显示 ,随着臭氧化的进行 ,促进了活性污泥生物量的减少 ,并有一定量的生物污泥被无机化 ,并且污泥的活性和存活性降低了。其中臭氧投加量低于 0 .1gO3 /gSS时污泥活性即大幅下降 ,而后污泥浓度才随着臭氧量的增加而显著降低。

| Abstract: | Effects of ozone on characteristics of activated sludge were investigated during a study on excess sludge reduction using ozonation. The results showed that both biomass activity and viability decreased along with ozonation. It was noted that biomass activity was noticeably declined at ozone dosages of lower than 0.1 g O 3/g SS but significant decrease in biomass concentration happened only at ozone dosages over 0.1 g O 3/g SS. |

| Keywords: | ozonation biomass concentration sludge activity |
