1. the cultural method of a denitrogenation granule sludge is characterized in that comprising following content:

  • (1) seed sludge is inserted in the aerobic reactor, carry out the enrichment culture of aerobic sludge, to obtain to tolerate the denitrogenation flora of high ammonia nitrogen with high-ammonia nitrogen low C OD waste water;

    (2) separation screening aerobic denitrifying bacteria from step (1) enrichment flora;

    (3) aerobic denitrifying bacteria of screening in the step (2) is tamed cultivation;

    (4) aerobic denitrifying bacteria that step (3) is obtained is inoculated into and carries out the denitrogenation granule sludge in the nitrifying granular activated sludge of step (1) and cultivate, when ammonia nitrogen and nitrogen removal rate reach the 50% denitrogenation granule sludge that can obtain to tame when above.
