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，题目是“细菌群落和运行条件对生物脱氮系统一氧化二氮排放的意义”。这项研究的基本思想是加速一氧化二氮（N2O）的还原在这项研究中，我的成就是：（1）我证明了 nosZ mRNA 是 N2O 还原活性的良好指标；（2）我在我们的反应器系统中鉴定了 N2O 还原细菌；通过对反应堆的长期运行和功能分析，提出了低N2O排放的最佳运行条件。在东京农工大学获得博士学位后，我访问了昆士兰大学先进水管理中心（AWMC）（ UQ），这是一个世界一流的废水处理技术研究中心，我所学到的有：（1）利用基于游离硝酸（FNA）的技术实现生物脱氮过程中的同步硝化和反硝化（SND）。 （2）通过创新方法（过硫酸盐和零价铁联合调理；零价铁和过氧化氢联合调理）提高厌氧消化污泥的脱水性。
