Abstract

With the extensive use of traditional energy, the structure of human energy consumption needs to be adjusted. Microalgae is a promising clean energy source, and growth model simulation is an effective method to predict the yield of large-scale microalgae culture and improve the production efficiency of microalgae. In this study, the effects of different artificial bioreactor depths on microalgae production were studied in depth by using numerical simulation, using and verifying the growth model of microalgae. Through research, it was found that when the depth of artificial bioreactor was shallow, the maximum microalgae production per unit volume was usually at the place where the initial inorganic nitrogen concentration was maximum, and when the depth was deeper, with the increase of the depth, The initial inorganic nitrogen concentration corresponding to the maximum yield of microalgae per unit volume is decreasing. It is suggested that the dilution rate of the culture medium can be controlled in the range of 0 to 0.005 d⁻¹ to obtain better production results, which can be used to guide the practice of microalgae production.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
