[Comparative evaluation of mathematical models of the process for the biological treatment of the wastes from antibiotic manufacture].
The main kinetic relationships of the process of biological oxidation of antibiotic production sewage were studied in laboratory models of mixer aerotanks. A relationship between the specific rates of BOD (biological oxygen demand) decreasing and BOD concentration in aerotanks was developed on the basis of the results relating to treatment of 8 types of the sewage within the ranges of the pure water BOD equal to 18-220 mg/l and the loads of 0.18-3.85 g BOD/g X day. To describe this relationship the following models were tested for their adequacy: Michaelis-Menten and Mozer models, a general model and a model of the first order reaction equation. The Mozer model with the relative root-mean-square deviation of 18.3 per cent proved to be the best in description of wide ranges of pure water BOD changing. The first order model with deviation of 12 per cent was the best in describing the process with low loads.
