Currently, waste disposal is strictly regulated by governments to reduce soil, water and air pollution caused by burial and direct discharge of waste into water. Anaerobic digestion has been touted as a means of dealing with organic waste while meeting humanity's energy needs. The process involves the production of biogas by microbial decomposition of organic compounds without oxygen, reducing the amount of organic matter to be removed. Anaerobic digestion produces a nutrient-rich digestate that can have agricultural value and produces methane-rich biogas that can be used as fuel directly or can be converted to compressed natural gas and liquefied natural gas.
The purpose of the study is to determine the influence of magnetic fields on the physicochemical processes of methanogenesis and the output of biogas during the fermentation of pig manure.
The work highlights the issue of the influence of a low-frequency electromagnetic field on the physicochemical processes of anaerobic fermentation of pig manure. The kinetics of chemical reactions in substrates under the influence of a magnetic field and its effect on the solubility of salts, acids and alkalis in solutions, as well as on the redox potential, pH value and electrophysical parameters of the substrate in the process of methanogenesis are considered. The yield of biogas under the influence of a low-frequency electromagnetic field on the process of anaerobic fermentation of the substrate and without influence was studied.
Key words: methanogenesis, electromagnetic field, physical and chemical processes, substrate, biogas
