Embodiment 1
[0057] To treat the pig manure produced in the pig pen in the farm.
[0058] Preliminary treatment of pig manure in simulated pigsty: 7.5kg per day defecation per stocked pig, weight ratio of straw to pig manure of pigpen bedding material of 1:4, pig manure charcoal to pig manure weight ratio of 1:50, choose 5m 2 To simulate a pig pen in an odorless place, take 22.5kg of fresh pig manure, add 5.7kg of straw powder, 0.45kg of pig manure charcoal, mix well and pile up, and the pig manure mixture will be produced after 3 days, and then press 50g / m 2 Spread pig manure charcoal powder (pass 30 mesh sieve) on the standard. During the stacking process, the odor concentration of the simulated pigsty is measured by the three-point odor bag method every day. After measurement, the odor concentration of the simulated pigsty is 0 (dimensionless).
[0059] Solid-liquid separation: solid-liquid separation of the slaughtered pig manure mixture with a flat-plate hanging bag unloading centrifuge to...
Embodiment 2
[0063] Preliminary treatment of cow dung in a simulated cattle farm: 17.5 kg of feces per day for each cow, and the weight ratio of straw to pig dung as the bedding material of the cow shed 1:5, and the weight ratio of pig dung charcoal to pig dung 1:50, choose one 10m 2 To simulate a cow pen in an odorless place, take 52.5kg of fresh cow dung, add 7kg of straw powder, 0.7kg of cow dung charcoal, mix well and pile up, the cow dung mixture will be produced after 2 days, and then press 50g / m 2 Spread cow dung charcoal powder (pass 30 mesh sieve) on the standard. During the stacking process, the odor concentration of the simulated bullpen is measured by the three-point odor bag method every day. After measurement, the odor concentration of the simulated bullpen is 0 (dimensionless).
[0064] Solid-liquid separation of cow dung mixture: The slaughtered cow dung mixture is separated by solid-liquid separation using a flat-plate hanging bag unloading centrifuge to obtain a solid cow du...
