This year, I got Ph.D degree under the title as “Significance of bacteria community and operation conditions on nitrous oxide emission from a biological nitrogen removal system”.The basically idea of this study is to accelerate nitrous oxide (N2O) reduction. In this study, my achievements are: (1) I showed nosZ mRNA as a good indicator for N2O-reducing activity; (2) I identified N2O-reducing bacteria in our reactors’ system; (3) Combined the long-term reactor’s operation and functional analysis, I suggested optimal operation conditions for low N2O emission.After I got Ph.D degree from Tokyo University of Agriculture and Technology, I visited to the Advanced Water Management Centre (AWMC), University of Queensland (UQ), which is a world-class research center about wastewater treatment technology. What I have learned there are: (1). Using free nitric acid (FNA)-based technology to achieve simultaneous nitrification and denitrification (SND) during biological nitrogen removal process. (2). Improving dewaterability of anaerobically digested sludge by innovative methods (combined conditioning with persulfate and zero-valent iron; combined zero valent iron and hydrogen peroxide conditioning).

今年，我获得了博士学位，标题为“细菌群落和操作条件对从生物氮去除系统产生的一氧化二氮发射的重要性”。这项研究的基本思想是加速一氧化二氮（N2O）的减少。在这项研究中，我的成就是：（1）我将NOSZ mRNA显示为N2O减少活性的良好指标； （2）我在反应堆系统中鉴定出N2O还原细菌； （3）结合了长期反应堆的运行和功能分析，我提出了低N2O排放的最佳操作条件。在获得东京农业与技术大学的博士学位后，我访问了昆士兰州大学（UQ）的高级水管理中心（AWMC）（UQ），这是世界级研究中心，这是世界范围的研究中心。我学到的是：（1）。在生物氮去除过程中，使用基于游离的硝酸（FNA）技术在生物氮去除过程中实现同时硝化和硝化化（SND）。 （2）。通过创新的方法（与硫酸盐和零价值铁结合条件和零价值的零元素铁和过氧化氢调节），通过创新方法改善了消化污泥的脱水性。
