陈垃圾反应器中脱氮微生物的脱氮机理

Mechanism of Microbial Nitrogen Removal in Aged Refuse Bioreactor

生物脱氮法因具有经济高效的特点而成为当今处理水体氮污染的热门方法。研究了陈垃圾反应器中的生物脱氮机理,其包括硝化阶段和反硝化阶段,分别由硝化菌和反硝化菌完成。此外,研究中还发现了厌氧氨氧化反应及生物膜同步硝化反硝化(SND)法等。

Owing to the economic and effective characteristics, biological denitrification technology has become a popular method in treating nitrogen pollution of water. The mechanism of biological denitrification in aged landfill was studied, and it included nitrification and denitrification stages, which were completed by nitrifying bacteria and denitrifying bacteria, respectively. In addition, the anaerobic ammonia oxidation reaction and biofilm simultaneous nitrification and denitrification method were found.
