Embodiment 1
[0024] Livestock and poultry manure (mixture of water and feces) was taken from a pig farm in Xiamen City, Fujian Province. The specific indicators are shown in Table 1 and Table 2. The annual slaughter volume of the selected pig farm is more than 5,000. Take 250 kg of feces and use a livestock and poultry manure solid-liquid separator for solid-liquid separation. About 100 kg of feces are separated, and about 150 kg of breeding wastewater are sorted out. The water content of the separated livestock and poultry manure is 80%. Corncobs are selected as the organic supplementary carbon source, and the particle size of corncobs is about 3cm. Assuming that the initial moisture content of the heap is 70% and the moisture content of corn cobs is 20%, then calculated by formula (1), the amount of corn cobs added is 20 kg. After mixing 100kg of feces and 20kg of corncobs evenly, lay them evenly on top of the sawdust. m. After the stacking is completed, the hot air is ventilated for 1...
Embodiment 2
[0030] Livestock and poultry manure (mixture of water and feces) was taken from a chicken farm in Xiamen City, Fujian Province. The specific indicators are shown in Table 4 and Table 5. The selected chicken farm has a breeding scale of more than 10,000 birds. Take 300 kg of feces, and use a solid-liquid separator for livestock and poultry feces for solid-liquid separation. About 130 kg of feces are separated, and about 170 kg of breeding wastewater are sorted out. The moisture content of the separated livestock and poultry feces is 83%. Corncobs are selected as the organic supplementary carbon source, and the particle size of corncobs is about 3cm. Assuming that the initial moisture content of the heap is 70% and the moisture content of corn cobs is 20%, then calculated by formula (1), the amount of corn cobs added is 33.8 kg. After stirring 130kg of feces and 33.8 kg of corncobs evenly, lay them evenly on the sawdust. m. After the pile is stacked, the hot air is ventilated ...
