Research into transient periodic processes of wastewater cyclotank aerobic treatment with biological sludge

The authors consider the theoretical pre-conditions for developing a model of transient periodic processes of communal wastewater aerobic treatment. The logical-mathematical model is based on the patters of cell growth kinetics and biochemical transformations of organic substances in the course of cell metabolism regulated by enzyme catalysis. The authors introduce the concept of the temporal structure of the operation cycle, consider the restrictions on the length of operations, the peculiarities of process description determined by individual phases of the process and parameter integration conditions observed during different phases.
