| 中文摘要 |
| 应用A/O中试试验装置处理实际生活污水，研究了在线过程控制对微生物种群活性和结构的影响，分子生物学FISH检测表明，污泥种群的优化是可能的也是有效的，基于DO、pH传感器在线信息动态控制DO浓度和曝气量可以实现系统中亚硝酸盐氧化菌（NOB）的淘洗，从而获得稳定的短程硝化反应.应用过程控制不但可实现污泥种群优化，提高系统脱氮效率，而且可最大程度的节约运行费用. |
| 英文摘要 |
| The structure and function of activated sludge community were studied in an A/O pilot-scale plant treating actual domestic wastewater. FISH results show the feasibility and effectiveness of sludge population optimisation. A/O process short-cut nitrification with process control of DO and aeration based on DO and pH on-line sensors can be achieved, and gradually eliminated nitrite oxidising bacteria, and therefore achieved nitrogen removal via the nitrite pathway. It can be realized sludge population optimisation, improving nitrogen removal and saving operational cost at the best with on-line process control. |
