摘　　要：氨氮是养殖水体主要的控制指标,自养硝化过程将水体中的氨氮经亚硝酸盐转化成硝酸盐,是水体中氨氮最常见的一种转化途径,也是循环水养殖系统中常用的氨氮控制方式。根据国内外关于循环水养殖水体中自养硝化过程的研究报道,结合养殖水体特征,分析了利用固定膜式自养硝化过程控制养殖水体氨氮的优势和劣势、水产养殖过程中影响自养硝化效率的因素以及在实际使用过程中的注意事项,对自养硝化过程的建立进行重点介绍,为实际应用提供参考。The recirculating aquaculture system is based on the reusing aquaculture water with high stocking densities. The ammonia nitrogen is the main control indexes of aquaculture water. In the process of autotrophic nitrification, ammonia nitrogen is converted into nitrate by nitrite, which is the most common pathway of controlling ammonia nitrogen in aquaculture water. This article reviews the present researches on the strength and shortcoming for nitrification of recirculating aquaculture water, and the factors affecting the efficiency of nitrification in the aquaculture system. The start-up of the nitrification is also focused on.
