The suppression of the inhibition effect by SO2 sulfur dioxide with the simultaneous action of two activators – P2O5 phosphorus oxide and NxOy nitrogen oxide, as well as the process of carbon dioxide absorption by chlorophyll-synthesizing microalgae Chlorella were studied in this work. The experimental dependences of the СО2 uptake dynamics by microalgae under the conditions of the SO2 inhibitor critical concentration action and the simultaneous presence of P2O5 and NxOy activators were shown. A mathematical description of the Chlorella microalgae biomass growth depending on the P2O5 and NxOy activators concentration, provided that there is a SO2 inhibitor constant concentration was obtained. The optimum values of the P2O5 phosphorus oxide and NxOy nitrogen oxides concentration at the SO2 inhibitor critical concentration for the carbon dioxide absorption by chlorophyll-synthesizing microalgae Chlorella process were established.
The research on the effect of sulfur oxides (SO2), nitrogen oxides (NxOy) and phosphorus oxides (P2O5) on carbon dioxide (CO2) uptake dynamics of chlorophyll synthesizing microalgae was conducted. The analytic dependences of microalgae growth rates under their CO2 uptake, SO2, NxOy and P2O5 concentrations were obtained. Mathematical models enabling to predict the maximum values of SO2, NxOy and P2O5 oxides concentrations without inhibiting the CO2 uptake dynamics of chlorophyll synthesizing microalgae were built based on the obtained experimental research results.
