Embodiment 1

[0020] A kind of preparation method of low pollution type pig manure organic fertilizer, comprises the following steps:

[0021] (1) Initial fermentation: adding mixed bacterial agents to pig manure can solidify the nitrogen and sulfur components in the pig manure, and increasing the oxygen content in the fermentation tank can improve the solidification effect and rate of nitrogen-fixing bacteria and sulfur bacteria, and reduce For the production of ammonia and hydrogen sulfide in pig manure, aerobic fermentation is carried out in a fermentation tank at 31°C, and 5.4% oxygen of the fermentation tank volume is introduced into the fermentation tank for 14.5 hours, and then lime water is added for chemical treatment to obtain primary fermentation pig manure;

[0022] (2) Autoclaving: Place the primary fermented pig manure in a far-infrared heating device for autoclaving at a temperature of 124°C, first heating at a pressure of 0.23MPa for 36min, then heating at a pressure of 0.43...

Embodiment 2

[0034] (1) Initial fermentation: adding mixed bacterial agents to pig manure can solidify the nitrogen and sulfur components in the pig manure, and increasing the oxygen content in the fermentation tank can improve the solidification effect and rate of nitrogen-fixing bacteria and sulfur bacteria, and reduce For the generation of ammonia and hydrogen sulfide in pig manure, aerobic fermentation is carried out in a fermentation tank at 34 ° C, and 6.5% oxygen of the fermentation tank volume is introduced into the fermentation tank for 15 hours, and then lime water is added for chemical treatment to obtain the first fermented pig manure;

[0035] (2) Autoclaving: Place the primary fermented pig manure in a far-infrared heating device for autoclaving at a temperature of 125°C, first heating at a pressure of 0.28MPa for 38min, then heating at a pressure of 0.47MPa for 24min, and then lowering the temperature to Raise to 152°C and heat for 4 minutes to produce sterilized pig manure;...

Abstract

The invention discloses a method for preparing a low-pollution pig manure organic fertilizer. The method comprises the following aspects: (1) initial fermentation: adding mixed bacteria into pig manure to perform pre-fermentation treatment; (2) high-pressure sterilization: placing the pre-fermented pig manure in far-infrared heating equipment for high-pressure sterilization treatment; (3) degradation and fermentation: respectively adding a fertilizer starter and EM bacteria into the sterilized pig manure to perform aerobic and anaerobic fermentation culture; (4) preparation of base fertilizer: adding additive components into the degraded and fermented pig manure to perform anaerobic fermentation for 5-6 days; (5) vacuum packaging: drying the pig manure organic base fertilizer until a moisture content is 5%-8%, refrigerating at a low temperature, and then packaging in vacuum for use. The pig manure organic base fertilizer produced by the method provided by the invention has advantages of no odor, rich nutrition, high plant absorption rate, low antibiotic content and few germs, and can improve plant growth, yield, oxidation resistance and pest-disease resistance.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing, and in particular relates to a method for preparing low-pollution pig manure organic fertilizer. Background technique [0002] With the continuous improvement of our country's economic level and the continuous improvement of people's living standards, the demand for pork products is increasing year by year. While increasing the scale of pig breeding, it is also increasing the damage to the environment; according to statistics 1 The average pig manure produced by a head of pigs is 20-24kg per day. Due to the high water content in pig manure, it is difficult to transport, it is difficult to handle, and the odor is heavy. The accumulation of a large amount of pig manure in the farm has caused serious damage to the surrounding environment, causing Residents' living environment has declined, groundwater pollution and the spread of germs and other issues. From the perspective of ...
