| 摘 要： | 含有溴离子的原水经臭氧氧化后会生成具有致癌性的溴酸盐，因此研究溴酸盐的控制对策成为饮用水处理领域的热点。通过模拟配水试验考察了新鲜活性炭向生物活性炭转化过程中对溴酸盐和有机物去除能力的变化。结果表明，活性炭滤池能有效去除溴酸盐，新炭在向生物活性炭转化的过程中滤池对溴酸盐的去除能力表现出逐渐减弱的趋势，待完全成为生物活性炭滤池后对溴酸盐的去除效果较差。不过，活性炭滤池和生物活性炭滤池对CODMn、UV254、致色有机物和CCl4都有较好的去除效果。 |

| Abstract: | Potential carcinogenic bromate is produced during ozonation of raw water containing bromide,and consequently the control of bromate has become a hot research topic in drinking water treatment.The change of organic and bromate removals during the transition from fresh activated carbon(FAC) to biological activated carbon(BAC) was investigated.The results indicate that the FAC filter can effectively reduce bromate but the reduction capacity gradually decreases during the transition.The reduction of bromate in the BAC filter is ineffective.However,both the FAC filter and the BAC filter can reduce COD_(Mn),UV_(254),color and CCl_4. |
| Keywords: | biological activated carbon bromate organic substance Yellow River water |
