The results show that nitrobacteria was influenced greatly by pH, which we controlled between 6.5 to 7.0 (appropriate to nitrobacteria). The removal rate of NH₄⁺ -N is 99% and the concentration of effluent NH₄⁺ -N is below 0.5 mg/L; because of the high DO value in the denitration section, the denitrobacteria was restrained and the effluent TN value was high, but the removal rate of TN can also reach 80%; the removal of TP is due to sample sludge and microorganism growth.
