Anokhina K. The mechanism and kinetics of animal wastes bioconversion

The thesis is devoted to the improvement of equipment and technological process of bioconversion by means of intensification of biogas output in anaerobic fermentation of animal wastes substrate. Theoretically justified parameters of bioreactors with mechanical mixing device for the intensification of energy-efficient bioconversion process. According to the results of mathematical modeling of the mechanism and kinetics of the mechanical processes of bioconversion an expert-modeling system of intellectual decision support to intensify the process of anaerobic fermentation of animal wastes by improving the mechanical mixing based on quantitative and qualitative impacts as linguistic variables is suggested. The regularities of the kinetics of the mechanical process of mixing biomass and sedimentation polydisperse medium organic animal waste substrate in bioreactor with vertical stirrer have been worked out. The influence of basic parameters of the mechanical mixing on the intensification of process of anaerobic fermentation of animal waste and the adequacy of theoretical dependences to the obtained experimental data has been checked. Energy-flow diagrams and bioconversion of the process intensification of anaerobic fermentation of biomass by improving the mechanical mixing is developed, their competitive ability is assessed and the technical and economic efficiency in recycling organic wastes of animal origin is defined. The results have been inculcated at LTD "Gas Equipment Plant" Alfa-Gazpromcomplect " (Ternopil) and of "Kovinko-kovbasy" (Vinnitsa region., p. Luka-Meleshkivska).
