Abstract
In this work, the biological treatment in sewage treatment plants is studied through the BSM2 Simulation Benchmark. The indicators of the process are those related to total nitrogen, ammonium in the effluent and nitrates. And as manipulable variables with greater influence on the previous indicators: the purge flow rate, the internal recirculation flow rate, the flow rate of the external carbon source, and the dissolved oxygen reference in the denitrification tanks. The influence and the most adequate ranges of operation of the previous variables are analyzed through stationary studies. Likewise, dynamic tests are carried out to determine the use of variables in control strategies. It is proposed a dual control of the ammonium in the effluent by manipulating, in different frequency bands, the recirculation and oxygen concentration. This also allows the regulation of the oxygen concentration at desired values to favor nitrification-denitrification or to minimize costs. The rest of the manipulable variables would be used in simple control loops.
