Effect on the Process of Biomethanogenesis of Pre-Treatment of Wheat Straw by the High Intensity High-Frequency Electromagnetic Field

Abstract

The purpose of the researches is the experimental determination of the effect of pre-treatment with the high-frequency electromagnetic field of high intensity on the appearance of deformations and structural rearrangements in the cells of wheat straw and on the intensity of biogas output.The set goal is achieved by the way of solving the following issues: obtaining chopped straw when it is grinding on a laboratory grinder to the fraction with average sizes of 5.2 mm x 1.5 mm and soaking in tap water for 15 minutes; measurement of distribution of the specific power of the electromagnetic field in the area where the samples of crushed wheat straw are located; comparison of images of the structure of straw under a light microscope for samples after influence by the high-frequency electromagnetic field of high intensity and control samples that were not exposed to such influence; carrying out fermentation experiments and researches of the process of biogas output within 20 days of a mixture of straw and inoculum for options with pre-treatment of wheat straw by the electromagnetic field of a Tesla’s transformer and without treatment by field. The most important results of the researches are: experimental evidence of the effectiveness of the method of pre-treatment of wheat straw by the high-frequency electromagnetic field of high intensity during the production of biogas. The significance of the obtained results is that the proposed approach to the formation of biogas technology with using the pre-treatment of wheat straw by the high-frequency electromagnetic field of high intensity ensures the intensification of biogas output.
