Abstract
Purpose. The aim of the research is to develop an authentic biotechnology model for obtaining energy from biomass of blue-green algae and mixing with additional energy resources. Investigation of fermentative reactions of biomethanogenesis and study of technological conditions of biogas production and control of compliance with the necessary сonditions. Methodology. Research methods include analytical and experimental studies using modern control and measuring equipment, using the leading techniques in the fields of environmental research and mathematical modeling of the investigated processes. Methods of statistical processing of experimental data were used; systematic scientifically grounded analysis was used for theoretical research. Findings. A biogas plant project with three technological lines for fermentation processing of a complex substrate has been developed. The main substrate proposed the use of excess biomass hydrobionts – blue green algae (BGA). A virtual complex for optimizing biogas production control has been developed. Its basis was the unique mathematical model of methanogenesis for the BGA. The unique coefficients and the results of the mathematical modeling of the Lab VIEV environment are determined - the maximum yield of biogas can be reached during the fermentation period – 25 days. Originality. The scientific novelty consists in utilizing a biogas plant for the fermentation of a complex substrate, namely: urban wastewater treatment facilities, dairy wastewater, agro-phytomass, leaf precipitate, manure, fecal drainage, BGA, and automatic control of production processes. Practical value. The practical value of the results obtained is to develop a project for a virtual biogas plant, which includes: the selection of optimum conditions for fermentation, the selection of necessary equipment, control equipment, technological, energy, design and hydraulic calculations of production, and determination of its profitability and payback period.
