Embodiment 1

[0069] When the carbon-nitrogen ratio of the mixture of human and livestock manure is 15:1 and the water content is 45%, the fermentation period of the mixture of human and livestock manure into organic fertilizer is 7 days, the fermentation temperature is 50-80°C, and the high temperature period is 70-80°C. The duration of the fermentation period accounts for 2 / 3 of the fermentation period.

[0070] The moisture content of the organic fertilizer is 31.50%. The organic matter content of the organic fertilizer is 54.30% based on the drying basis, the total nitrogen content based on the drying basis is 7.62%, the total potassium content based on the drying basis is 5.37%, and the total phosphorus content based on the drying basis is 4.53%, the content of coliform bacteria in the organic fertilizer is 10 / g, the pH value is 7.5, and the germination rate of the seeds fertilized by the organic fertilizer is 110.86%.

Embodiment 2

[0072] When the carbon-nitrogen ratio of the mixture of human and livestock manure is 10:1, and the water content is 45%, the fermentation period of the mixture of human and livestock manure into organic fertilizer is 15 days, the fermentation temperature is 50-80°C, and the high temperature period is 70-80°C. The duration of the high temperature period accounts for 2 / 3 of the fermentation period.

[0073] The moisture content of the organic fertilizer is 34.20%. The organic matter content of the organic fertilizer based on the drying basis is 50.20%, the total nitrogen content based on the drying basis is 7.04%, the total potassium content based on the drying basis is 4.19%, and the total phosphorus content based on the drying basis is 4.96%, the content of coliform bacteria in the organic fertilizer is 180 / g, the pH value is 7.9, and the germination rate of the seeds fertilized by the organic fertilizer is 90.21%.

Embodiment 3

[0075] When the carbon-nitrogen ratio of human and livestock manure mixture is 20:1, and the water content is 50%, the fermentation period of human and animal manure mixture into organic fertilizer is 16 days, the fermentation temperature is 50-80°C, and the high temperature period is 70-80°C. The duration of the high temperature period accounts for 2 / 3 of the fermentation period.

[0076] The moisture content of the organic fertilizer is 34.60%. The organic matter content of the organic fertilizer is 46.40% based on the drying basis, the total nitrogen content based on the drying basis is 6.51%, the total potassium content based on the drying basis is 3.87%, and the total phosphorus content based on the drying basis is 4.59%, the content of coliform bacteria in the organic fertilizer is 160 / g, the pH value is 6, and the germination rate of the seeds fertilized by the organic fertilizer is 98.47%.

Abstract

The invention relates to a production method for preparing an organic fertilizer by mixing livestock and poultry manure with human manure, which comprises the following steps: S1, manure mixing: mixing livestock and poultry manure and human manure in proportion to obtain a human and animal manure mixture, so that the carbon nitrogen ratio of the human and animal manure mixture is (10-15): 1, and the water content is 40-50%; s2, biological fermentation: adding high-temperature thermophilic bacteria into the human and animal excrement mixture until the content of the thermophilic bacteria is more than or equal to 5 * 10 < 8 > / kg, and fermenting the human and animal excrement mixture under the action of aeration and stirring to obtain an organic fertilizer; and s3, discharging of the organic fertilizer: calculating the current discharge amount, and remaining the rest, wherein after the reserved organic fertilizer is mixed with the human and animal excrement mixture fed again, the content of high-temperature thermophilic bacteria in the mixture is greater than or equal to 5 * 10 < 8 > / kg. The method has the beneficial effects that the problem of environmental pollution caused by the human and animal excreta in rural areas is solved, household treatment of the human and animal excreta is realized, various harms to the environment caused by application of the traditional inorganic fertilizer to farmlands are avoided, the cost of the inorganic fertilizer can be reduced, and the economy is better.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a production method and a production system for preparing organic fertilizers by mixing poultry and animal manure with human manure. Background technique [0002] With the rapid development of the farming industry in rural areas, large-scale farming of poultry and livestock in rural areas has produced a large amount of poultry manure; at the same time, most of the rural areas still use dry toilets, and the amount of human manure produced is also considerable. If these human and animal wastes are piled up without any treatment, on the one hand, it is easy to breed mosquitoes and bacteria, leading to frequent outbreaks of infectious diseases; on the other hand, it will cause serious non-point source pollution to the atmosphere, soil and water. Therefore, poultry manure needs to be treated. [0003] When handling poultry manure and human manure in rural areas, due to th...
