The invention discloses a device and a method for realizing partial short-range nitrification-anaerobic ammonia oxidation by adding hydroxylamine, and belongs to the field of urban domestic sewage biological treatment. For two-stage partial short-range nitrification-anaerobic ammonia oxidation, the stable operation of the short-range nitrification is crucial to a process; the short-range nitrification is very difficult to start and maintain stably only through process parameter control; a very good nitrite accumulating effect can be achieved by adding the hydroxylamine in the patent; partial short-range nitrification reactors can be started and high nitrite accumulation can be maintained within a short time. The hydroxylamine serves as an intermediate product in a nitrifying process, is a reducing agent of ammonia monooxygenase and a stimulating agent of AOB (Ammonia Oxidizing Bacteria) and can improve the cell yield of the AOB; meanwhile, the hydroxylamine is an inhibiting agent of NOB (Nitrite Oxidizing Bacteria) and can elutriate the NOB. Compared with a conventional denitrogenation process, a partial short-range nitrification-anaerobic ammonia oxidation process can save aeration quantity and carbon source, and is particularly suitable for urban domestic sewage with low C/N.
