<p>Context. The actual problem of development of mathematical models of processes of wastewater treatment, subject to automatic control was resolved.</p><p>Objective to develop a mathematical model of the process of wastewater treatment from biological substances immobilized microorganisms in multistage anaerobic-aerobic method of purification which takes into account the oxidation of organic matter, reproduction and death of bacteria as a set of interaction of various factors, depending on the concentration of dissolved oxygen and pollutants organic matter.</p><p>Method. We used the methods of mathematical physics and hydrodynamics to build mathematical models of processes of cleaning fluids, common approaches to building model problems in which some components dominate over others. The mathematical model of biological wastewater treatment was built. It takes into account the changes in the concentrations of pollution, sludge and oxygen in reproduction and the withering away of the bacteria in biological reactors of various types.</p><p>Results. The solution of corresponding model problem was found by using functions pdepe environment MatLab. The results of calculations of concentration distribution of contamination, sludge and oxygen cleaning fluid over time were shown. It takes into account the ability of bacteria to multiply and dying.</p>Conclusions. The experiments confirmed the adequacy of the constructed model. Based on the results, the automated control system was developed. It controls permissible concentration of pollution in wastewater, which provides energy-saving principles of installation. |
