摘要：

A kinetic model was applied for comparing the 1 sludge system with the 2 sludge system in the oxidation of nitrogenous substrates. It verified that some organic substances, members of different classes of compounds usually present in sewage, do not exert an appreciable inhibiting effect on the activity of the nitrifying bacteria. The growth yield coefficient (Y) and the maximum growth rate (.mu.-M) for these bacteria were determined using new methods, since correct application of the kinetic model requires the most accurate estimate possible for these parameters. The comparison between the 2 processes was made in the case of 2 limiting concentrations for the nitrification reactor in the 2 sludge system. The important role played by the settling characteristics of the sludge was pointed out.
