Abstract
This article presents the results of laboratory and pilot studies on biogas from a mixture of liquid manure and wastewater. The results showed that by adding cow manure in sewage sludge can intensify the process of anaerobic digestion. Thus, an increase of the yield of biogas reactor. According to the results of laboratory and semi-experimental studies found that the optimum fermentation parameters are pH - 6,75-7,45, alkalinity - 48-100 mEq/L and the content of CO2 in the biogas should be between 26-40%. And the best time boundary fermentation are 5-10 days at a humidity of 90-96% and 17-20% loading dose.
