The effect of methane fermentation in a biogas plant on agrochemical composition of poultry droppings and pig manure was investigated, as well as the degree of their contamination with helminth eggs was
estimated. It was found that in conditions of mesophilic temperature regime, the amount of organic and mineral nitrogen and carbon (components of humic acids) increases in the fermented mass, as compared with the mass before fermentation, suggesting about the activity level of microbiological processes at the expense of bacterial biomass augmentation. Consequently, the fermented biomass, when used as fertilizer, will contribute to the formation of humus more than unfermented manure and, thereby, it will increase soil fertility. Under mesophilic temperature regime there is a decrease in the number of helminth eggs, while under thermophilic temperature
regime there is a total absence of helminth eggs. Under a more active fermentation (the activity of the release of biogas bubbles, which pass through water cleaning device), fewer helminth eggs were found after termination of fermentation, due to the life activity of bacteria under mesophilic temperature regime as compared with weak
fermentation. A complete egg survival post-fermentation was observed when the organic matter subjected to fermentation, for certain reasons, has not fermented. |
