摘　　要：我国水产养殖业正朝着高密度、集约化的方向发展,而养殖水体中NH_(4)^(+)-N、NO_(2)^(-)-N、NO_(3)^(-)-N的积累问题严重影响了水资源循环效率及水产品品质。异养硝化-好氧反硝化(HN-AD)菌群可以在较高溶解氧条件下去除养殖水体中的氮素,是净化养殖水质的关键核心。简述了具有HN-AD功能的微生物分类现状,阐述了具有HN-AD功能的微生物群落特征,分析了HN-AD菌在耐盐、降解农药和去除抗生素等方面的拓展效能,同时探究了基于环境因子的HN-AD过程调控效率,最后预测HN-AD技术在未来的发展方向。在可持续发展与“碳达峰”双重目标的驱动下,HN-AD技术正朝着更高效、可持续性和低碳排放的方向发展,助力水产养殖业不断提高水循环利用率和养殖密度。Aquaculture industry in China is developing towards high density and intensification,and the accumula-tion of NH_(4)^(+)-N,NO_(2)^(-)-N and NO_(3)^(-)-N in water bodies has seriously affected the efficiency of water resources cycling and the quality of aquatic products.Heterotrophic nitrification-aerobic denitrification(HN-AD)technology can re-move nitrogen in aquaculture water under high dissolved oxygen conditions,which is the core technology for purify-ing aquaculture water quality.The classification status of microorganisms with HN-AD function was briefly de-scribed,and the characteristics of microbial communities with HN-AD function were expounded.The expanded effi-ciency of HN-AD bacteria in salinity tolerance,pesticide degradation and antibiotic removal was analyzed.Mean-while,the efficiency of HN-AD process regulation based on environmental factors was explored,and the develop-ment direction of HN-AD technology in the future was predicted.Driven by the dual goals of sustainability and“peaking carbon”,HN-AD technology is moving towards greater efficiency,sustainability and low carbon emis-sions,which will help the aquaculture industry to continuously improve water recycling and farming density.
