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 ...

Abstract

The invention discloses a synergetic degrading method of livestock and poultry manure and culture waste water. The synergetic degrading method of livestock and poultry manure and culture waste water is invented based on aerobic composting of livestock and poultry manure and pollution control of livestock and poultry culture waste water. According to the synergetic degrading method of livestock andpoultry manure and culture waste water, livestock and poultry culture waste water is sprayed onto livestock and poultry manure aerobic composting stacks based on the degradation capacity of microorganisms in aerobic composting stacks on pollutants and high temperature characteristics of aerobic composting stacks, so that synergetic degrading of livestock and poultry manure and culture waste wateris realized. Reasonable selection of a method used for prolonging high temperature period is adopted based on composting speed. The synergetic degrading method can be used for treating livestock andpoultry manure and culture waste water at the same time, the technology process is simple, running cost is low, recycling of pollutants in waste water in composting is realized, compost efficiency isincreased, waste water secondary pollution is reduced, composting period is short, batch treatment of manure is realized, and the synergetic degrading method is suitable for large scale culturing farmmanure treatment.

Description

technical field [0001] The invention relates to a collaborative consumption technology of livestock and poultry manure and livestock and poultry breeding wastewater based on aerobic composting, which is suitable for the resource utilization of livestock and poultry manure and the treatment of livestock and poultry wastewater, and belongs to the resource utilization of solid waste and wastewater pollution control methods. Background technique [0002] With the continuous improvement of the specialization, scale and intensification of my country's animal husbandry, the amount of livestock and poultry has increased significantly, which not only meets people's demand for meat, eggs and milk, but also leads to a significant increase in the discharge of livestock and poultry manure. According to statistics, the daily excrement of a 10,000-head pig farm is about 190 t, which contains about 40% of feces and about 60% of urine. In 1999, the amount of livestock and poultry manure prod...
