Problems solved by technology

[0002] With the call of the country for energy saving and environmental protection and the increasing demand for pork, pig farmers are gradually developing into large farmers. Usually a large pig farm can raise thousands or even tens of thousands of pigs at the same time. A large amount of feces and urine are produced. In daily management, it is inevitable to use a large amount of water to wash the ground, and to clean, collect, and treat pig excrement. This requires a lot of manpower, energy, and water, and the cleaning effect is not good. If the excrement of the pigs is not cleaned up in time, it will easily cause accumulation, the dirt will adhere to the pigs, the pigsty will be dirty and wet, and the pigs will Growing in this environment directly affects their health status and the quality of meat products. Coupled with poor ventilation, adult pigs need low temperature and comfort, and the poor heat preservation effect cannot meet the living conditions of piglets, which will easily lead to epidemics and increase Reduced the work intensity and difficulty of the breeders

Embodiment 1

[0038] Step 1: The pigs are raised on the upper raised net bed 3 and the lower raised net bed 4 of the pig house, and the pigs are trained to defecate and urinate in a fixed position to ensure that the excrement accumulates and ferments on the floor below the raised net bed;

[0039] Step 2: Use the manure scraper under the elevated net bed to push the manure into the manure treatment tank, and add 1 kg of brown sugar per 10 tons of manure and 3 per 10 tons of manure in the manure treatment tank. After mixing for 0.5 hours, add strains per kilogram, suck and transport to the ectopic fermentation bed and add 12 tons of straw powder for every 10 tons of feces and urine to carry out mixed fermentation, mix and pile up, turn the pile 3 times every 5 days, and press Add 2 kg of added strains to every 10 tons of manure to get old manure with a water content of 25-35%;

[0040] Step 3: Add 1 ton of fresh manure to the old manure for every 10 tons of old manure, add 220 kilograms of s...

Embodiment 2

[0043] Step 1: The pigs are raised on the upper raised net bed 3 and the lower raised net bed 4 of the pig house, and the pigs are trained to defecate and urinate in a fixed position to ensure that the excrement accumulates and ferments on the floor below the raised net bed;

[0044] Step 2: Use the excrement scraper under the elevated net bed to push the excrement into the excrement treatment tank, and add 5 kg of brown sugar per 10 tons of excrement and 2 kg per 10 tons of excrement in the excrement treatment tank. After mixing for 1.5 hours, add strains in 1 kg, suck and transport to the ectopic fermentation bed and add 8 tons of straw powder for every 10 tons of manure and urine for mixed fermentation, mix and pile up, turn the pile once every 8 days, after 30 days, press Add 3 kg of added strains to every 10 tons of manure to get old manure with a water content of 25-35%;

[0045] Step 3: Add 4 tons of fresh manure to the old manure for every 10 tons of old manure, add 18...

Embodiment 3

[0048] Step 1: The pigs are raised on the upper elevated net bed 3 and the lower elevated net bed 4, and the pigs are trained to defecate and urinate in a fixed position to ensure that the excrement accumulates and ferments on the floor below the elevated net bed;

[0049] Step 2: Use the manure scraper under the elevated net bed to push the manure into the manure treatment tank, and add 3 kg of brown sugar per 10 tons of manure and 2.5 grams per 10 tons of manure in the manure treatment tank. After mixing for 1 hour, add strains per kilogram, and then suck them to the ectopic fermentation bed and add 10 tons of straw powder for every 10 tons of feces and urine to carry out mixed fermentation. Add 2.5 kg of added strains to 10 tons of feces and urine to obtain old feces with a water content of 25-35%;

[0050] Step 3: Add 2 tons of fresh manure to the old manure for every 10 tons of old manure, and add 200 kg of straw powder for every 10 tons of old manure to carry out seconda...

Abstract

The invention discloses a high-value treatment method for recycling pig dung and urine, capable of maximally avoiding nutrient loss of fertilizers and saving the strain cost by 90% or above. The treatment method comprises the following steps: 1, allowing pigs to excrete dung and urine on a net bed at the upper layer of a pig house; 2, pushing the fresh dung and urine on a lower net bed of the pighouse into a fecal treatment tank by using a fecal scraper, adding granulated brown sugar and a strain into the fecal treatment tank, performing mixing for 0.5-1.5 h, pumping the obtained mixture intoan ectopic fermentation bed, mixing the mixture with straw powder, fermenting the obtained mixture, performing mixing composting, turning over the obtained heap 1-3 times every 5-8 d, and supplementing the strain 20-30 d later to obtain old manure with the water content of 25-35%; and 3, adding fresh dung and urine into the old manure, adding the straw powder, and carrying out secondary fermentation for 40-60 d to obtain a completely-fermented bioorganic fertilizer.
