BIO-ENERGY FROM PIG'S MANURE

After settling, in the sample of pig’s manure, before and after anaerobic fermentation different layers appear: foam, fine colloids, floating particle-colloids and sediment-rude particles. During the anaerobic treatment it being favourable for maintaining the anaerobic fermentation was examined. It was shown that the layer from the bottom, sediment-rude particles, achieved the best results. During the anaerobic fermentation pig’s manure was stabilized and its quality improved. Produced biogas contained more than 88 vol.% of methane. The degradation of organic matter was 50 % at pH value 6.5 and temperature 35 oC during the anaerobic fermentation that lasted 7 days.
