Study of the use of substandard flour as a co-substrate to increase biogas yield
Annotation
Purpose. Increasing the biogas yield due to the rational mode of manure fermentation with the addition of substandard flour as a co-substrate.
Methods. Experiment planning, methods of mathematical statistics. Analytical processing of experimental data. was carried out using the methods of mathematical statistics and probability theory on a computer in Excel and MathCad. Optimization problems were solved using the dichotomy method.
Results. In methane fermentation of cattle manure with the addition of wheat flour as a co-substrate, the maximum yield of biogas was observed when adding 2.3% flour to the substrate. If the mass of flour increases to 10.6% methane fermentation quickly stops.
Conclusions. Based on the research, the following results were obtained:
• for quasi-continuous loading of the methane tank, the optimal flour content in the substrate is determined, which is 3%;
• substantiated recommendations on the rational content of flour in the substrate in the range of 2.3–4%, which provides an increase in biogas yield during fermentation of a mixture of cow manure and flour in 1.5–2 times.
Keywords: biogas, cosubstrate, methane tank, gasholder, cattle manure, flour, grain waste, bread waste, experimental researches.
