The paper presents a comparative analysis of five models describing the changes in BOD5 based on results of the experimental research. The model of Thomas (1950), Navone (1960), Fujimoto (1964), Adrian and Sanders (1992-1993) as well as Young and Clark (1965) used by Adrian and Sanders (1998) were studied. The values of BOD5 were measured for 5 days with the measurement step of 3 h in every sample out of 92. Therefore, each course of the variation was described by 40 measurement points. To define the influence of the processes of nitrification on the level of BOD5, each sample was examined with addition of an inhibitor of nitrification and without it. It was found that reaction constant did not depend on the final value of BOD in the models of the firstt order (Thomas, Navone and Fujimoto) contrary to the models of the second order (Young and Clark), and especially the half order (Adrian and Sanders). It is the easiest to define the lag phase of the time dependence BOD by the model of Thomas, which clearly depicts the border between the growth sequence of BOD and the initial fluctuations of the growth. The influence of the nitrification inhibitor on the course of the BOD was not noticed in all samples. It suggests that the process of nitrification occurred in a part of the samples almost from the first day and more often from the second or third day and in others this process did not occur in the whole measurement period (5 days) at all.
