| 摘要: |
| 为了比较活性炭与生物活性炭对溴酸盐的去除效果,采用水厂中试模型试验考察了活性炭表面的生物量及溴酸盐去除率的变化.结果表明:新鲜活性炭对溴酸盐的去除率为57.1%,在活性炭向生物活性炭转化的过程中,随着活性炭表面生物量的增加,炭柱对溴酸盐的去除效果逐渐提高.经过8个月的中试模型连续运行,溴酸盐的去除率提高至75.4%,成熟生物活性炭对溴酸盐的去除效果稳定,从而证明生物活性炭比活性炭更有利于溴酸盐的去除. |

| Abstract: |
| In order to compare the bromate removal effect of activated carbon with that of biological activated carbon,by making pilot-scale test,the changes of biomass on activated carbon surface and bromate removal rate were investigated. The results indicated that the bromate removal rate of new activated carbon was 57. 1% ,and as the biomass increased,the removal effect of bromate was improved gradually during transformation process from granular activated carbon to biological activated carbon. After 8 months,the bromate removal rate achieved 75. 4% and the concentration of bromate could be controlled by biological activated carbon steadily,which proved that biological activated carbon was more suitable for bromate removal than granular activated carbon. |
