Modelling of Wastewater Treatment Process in the Class of Distributed Parameters Objects

摘要

The system "biological reservoir - sedimentor" is the most often used system in aerobic biological wastewater treatment. The conventional bioreactors for cultivation of microorganisms aim to produce a maximum amount of biomass. In contrast, the system "biological reservoir -sedimentor" aims to keep some low concentration of organic contaminating substances in sedimentor outlet. In order to design a proper control, first of all an adequate process model has to be obtained. This paper presents the modelling and the parameter identification of the process, carrying out in the system "biological reservoir - sedimentor". To obtain a model with higher accuracy degree, the process of wastewater treatment is considered as object with distributed parameters.
