The results showed that: the first in the reactor is running 56d,[link widoczny dla zalogowanych], NH + a N, NOr-N, TN removal rate of the other q points to 99.8%, 98.8,9 O. 2, the successful launch of the anaerobic ammonium oxidation, and subsequent operation of the treatment effect of stability. ANANMMOX stable operation, the removal of NH +-N, No one No one N and N generated by the ratio of 1:1.61: O. 25, the effluent pH stabilized at 8.3 or so, forward, little change water alkalinity. Obtained with the anaerobic ammonium oxidation activity of the biofilm is brown and the bottom of the reactor to form a brown and pink two granular sludge.
