| 中文摘要 |
| 采用生物粉末活性炭-超滤（BPAC-UF）组合工艺对模拟微污染水源水中的嗅味物质进行了去除试验，并对组合工艺中微生物量的分布和变化进行了测定. 结果表明，相比混凝沉淀常规工艺，BPAC-UF组合工艺对微污染水源水中的嗅味物质有较好的控制效果，对二甲基三硫醚、2-甲基异莰醇和β-紫罗兰酮的平均去除率分别可达77.51%、65.86%和98.43%，并且对原水冲击负荷有更好的适应性；炭池是组合工艺中去除嗅味物质的主要单元，其微生物量远高于其它区域；炭池生物量变化平稳，组合工艺对原水中嗅味物质的去除具有稳定性. |
| 英文摘要 |
| The odorants in simulated micro-polluted source water were removed by the Biological Powdered Activated Carbon-Ultrafiltration (BPAC-UF) combined process, and variations of microorganisms in the combined process were discussed. Compared with the conventional process of coagulation and sedimentation, BPAC-UF combined process had better performance in controlling odorants in micro-polluted source water. The average removal rates of dimethyl trisulfide, 2-methylisoborneol and β-ionone reached up to 77.51%, 65.86% and 98.43%, respectively. The process was more adaptable to raw water shock load. The carbon tank which had much more microbial biomass than other areas was determined to be the main unit for removing odorants. The biomass changed smoothly in the carbon tank, while the removal of odorants in raw water was stable in the process. |
