Исследование влияния постоянного магнитного поля на кинетику анаэробного процесса при получении биогаза из твердых коммунальных отходов

Abstract

The aim of the work is to study the effect the magnetic fields of permanent magnets have on the amount of biogas produced during degradation of municipal landfill substrates. To increase the yield of biogas, the influence of various physical materials on microorganisms is studied. The use of different permanent magnet field polarizations for modifying the activity of microorganisms is discussed. Matters concerned with producing biogas from municipal waste are addressed (in so doing, food waste making up the required biomass was analyzed). Experiments have shown that the best effect is obtained at a temperature of 37 °C. In practice, such temperature can be maintained quite easily because under the described climatic conditions, the warm period of the year is more than 6 months. At this temperature, self ignition of the biomass is ruled out. The described experiment was carried out in the city of Stuttgart, Germany at the laboratory of the State Institute of Agricultural Engineering and Bioenergy of the University of Hohenheim. The experiment was carried out under direct scientific leadership of Dr. Andreas Lemmer. The experiment was conducted for 35 days at a temperature of 37 °C and pressure in the reactor of 970 mbar. It has been shown that magnetic fields have a significant influence on the fermentation process and on the gas yield. Particular steps recommended to improve the waste fermentation process are suggested.
