摘　　要：介绍了循环水养殖系统及其系统中NO_3^--N的产生及危害,叙述了自养和异养反硝化脱氮技术的原理,并总结了2种类型反硝化技术去除NO_3^--N的影响因素以及工艺。认为随着分子生物学的发展,菌体的群落变化、代谢过程以及氮的来源和去向会更加明晰,新型反硝化细菌如好氧反硝化菌将被发现。如果可以在同一个反应器内实现硝化反硝化,不仅可以简化反应器程序,而且降低RAS系统运行成本,是未来反硝化在养殖水体脱氮处理中的一个重要方向。The recirculating aquaculture system and the production and harm of nitrate nitrogen in this system were introduced, the principle of autotrophic and heterotrophic denitrification technology was described and the influencing factors and processes of two denitrification technologies for NO3-^-N removal were summarized. It was considered that with the development of molecular biology, the changes of bacterial community, metabolic processes and the sources and destinations of nitrogen will be gradually studied in depth, new type denitrifying bacteria such as aerobic denitrifying bacteria will be found.It was proposed that nitrification and denitrification in the same reactor will simplified reactor procedure and reduced RAS system operation cost, which will be an important development direction of nitrogen removal in recirculating aquaculture system in the future.
