Waste from livestock farms contains various pathogens, including eggs and larvae of helminths—pathogens parasitic diseases harmful to animals humans. One the methods for their effective processing obtain biofertilizer biofuel is anaerobic digestion, which requires further improvement completely suppress viability pathogenic microorganisms in mesophilic conditions. To this end, use digestion under sulfate reduction conditions pathogens using biogenic hydrogen sulfide promising. Consequently, study aims effect a sulfur-containing additive such as phosphogypsum on disinfection pig manure during digestion. Egg mortality was already found increase significantly compared control (80% more), even at minimum concentration (5%), fifth day experiment. At same time, maximum (100% Trichuris suis eggs) recorded 10% phosphogypsum, starting 10th study. Our experiment showed that changes could positively affect digestate disinfection. However, research needed optimize process an combination with production environmentally safe organic fertilizers high-quality biogas high level methane.
