| 摘 要： | 通过试验考察了活性炭、陶粒以及挂膜陶粒对溴酸盐的去除效果，分析了微生物对溴酸盐的降解作用。结果表明，在滤池以及生物活性炭滤池内成熟的微生物膜对溴酸盐有降解能力，溴酸盐去除量与水力接触时间的关系为9．16μg（L·h）。在活性炭（GAC）吸附以及微生物降解协同作用下，可以在不增加运行成本的基础上稳定、有效地控制溴酸盐。 |

| Abstract: | The removal efficiencies with activated carbon, ceramsite and biofilm forming ceramsite were investigated, and biological degradation to bromate was also introduced. The results showed that mature microorganisms in filter and BAC bed were able to biodegrade bromate. The bromate removal capability was 9.16μg/（ L·h） calculated. Under the synergism of GAC adsorption and microorganism degradation, bromate could be controlled stably and effectively without increasing operation cost. |
| Keywords: | bromate GAC adsorption microorganism degradation ceramsite ozone sand filter |
