For biogas fermented fertilizers, the sealed storage period is required to be more than 30 days; the high-temperature biogas fermentation temperature is 532°C for 2 days; the parasite egg sedimentation rate of 95% or more in water and feces can not eliminate live schistosome eggs and hookworm eggs; biogas digesters The residue can be used after being harmlessly treated.
