| 中文摘要 | 为了提高氧化沟单沟系统的脱氮能力,通过现场测试对Carrousel氧化沟单沟系统内部溶解氧(DO)的分布、传输特性进行了研究,通过中试试验对氧化沟适宜同步硝化反硝化过程发生的DO条件进行了研究.结果表明,沟内DO环境受曝气机的开启状态和进水负荷日动态变化的影响显著,DO的分布和输移过程的推流特性有利于同步硝化反硝化过程的发生,沟内适宜同步硝化反硝化过程发生的好氧区域空间比例为0.3~0.5,并随着水力停留时间缩短而逐渐增大.; To enhance the efficiency of removal of nitrogen, the distribution and process of transfer of dissolved oxygen was carried out in a real Carrousel oxidation ditch. The optimum condition of oxygen for the occurrence of simultaneous nitrification and denitrification (SND) was carried out in a pilot-scale oxidation ditch. The influence of the fluctuation of influent and control of aerators on the distribution of dissolved oxygen in the ditch was obvious. The characteristics of distribution and transfer of dissolved oxygen in the ditch were feasible for occurrence of SND. The proportion of the aerobic volume fraction changed from 0.3 to 0.5 corresponding to an optimal range for the removal of total nitrogen, the proportion increased with the decrease of hydraulic retention time. |
