The invention relates to a method for removing ammonia nitrogen and nitrites in a pond culture water body in a nitrification process, belonging to the technical field of aquiculture. A filter material mesh cage is put in the pond, the periphery of the filter material mesh cage is enclosed by polyethylene meshes, a polypropylene filter material is put in the filter material mesh cage, the bottom of the filter material mesh cage is provided with an aeration tray, and the filter material mesh cage is fixed to the bottom of the pond through piles. The simple method of putting the filter material in the culture pond culture water is adopted, thereby saving the external building cost and water circulation cost. The inside of the mesh cage is moderately aerated, thereby keeping the sufficient communication between the filter material and water, and increasing the dissolved oxygen in the culture water body. 本发明涉及种应用硝化过程去除池塘养殖水体中氨氮和亚硝酸盐的方式，属于水产养殖技术领域，池塘中放入滤材网箱，滤材网箱的四周通过聚乙烯网片围成，滤材网箱内放入聚丙烯滤材，滤材网箱底部设有爆气盘，滤材网箱通过桩固定在池塘底部。其
