The mathematical modeling and monitoring for process of a biological sewage treatment

Abstract

The urgency of present problem is caused by necessity of operative control of biological sewage treatment processes. At present these processes are realizing in aeration tanks of sewage treatment plants both municipal and of large enterprises. A process of biological treatment is being checked by chemical analysis practically by hand. By the way a duration of checking procedure is commensurable with the time the sewage water is passing through an aeration tank. Thus any operative control of sewage treatment is practically impossible. In the present work it is proposed to use for operative control the hardware- software complex (HSC) AQUATEST-AT4M, that is able to produce an analysis of water quality in some minutes. By the way the measurement data give an opportunity to identify a mathematical model of these biological sewage treatment. In this work there are presented the results of experiments and of mathematical modelling of work of the Kirov City communal systems sewage treatment plants (KCS STP).
