Abstract:

Aquaculture industry in China is developing towards high density and intensification, and the accumulation of NH4 +-N, NO2 --N and NO3 --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 remove nitrogen in aquaculture water under high dissolved oxygen conditions, which is the core technology for purifying aquaculture water quality. The classification status of microorganisms with HN-AD function was briefly described, and the characteristics of microbial communities with HN-AD function were expounded. The expanded efficiency of HN-AD bacteria in salinity tolerance, pesticide degradation and antibiotic removal was analyzed. Meanwhile, the efficiency of HN-AD process regulation based on environmental factors was explored, and the development 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 emissions, which will help the aquaculture industry to continuously improve water recycling and farming density.

Key words: heterotrophic nitrification-aerobic denitrification, microflora, aquaculture wastewater, low carbon

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NH4 +-N、NO2 --N、NO3 --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。
