Embodiment 1

[0029] A method for generating heat by fermenting pig manure, comprising the following steps:

[0030] One, with 4500kg of pig manure in parts by weight, 4500 kg of sawdust, 1800kg of rice bran powder and 0.7kg of fermented bacterial classification, after mixing, add water and insulate and ferment to obtain the original bacteria; the water content is controlled at 25 ~ 60%, and the preferred water content is controlled at 30-45%, since the purpose of the present invention is mainly to obtain the heat generated by the fermentation of pig manure, it is beneficial to reduce the water content to prolong the fermentation time, and reducing the water content can inhibit the growth of miscellaneous bacteria. The fermentation time is 15-40 days, wherein summer is 15-20 days, and winter is 30-40 days.

[0031] Optimized, stack the prepared materials into long strips with a width of 1.5-2 meters and a height of 0.3-0.4 meters, cover them with plastic film, and cover the film with straw ...

Embodiment 2

[0037] 1. Mix 4,800kg of pig manure, 4,800kg of sawdust, 2,000kg of rice bran powder and 1kg of fermented bacteria in parts by weight, add water and heat-preserve and ferment to obtain the original bacteria; the water content is controlled at 40-50%.

[0038] In the fermented strains, the content of thermophilic coprophagous by weight is 50%.

[0039] In the fermented strains, the content of anaerobic and facultative anaerobic thermophilic bacteria is 30% by weight.

[0040] 2. Put 10000kg of pig manure in parts by weight, 10000kg of sawdust and 1000kg of original bacteria into the fermentation bed in the pig house for fermentation after adding water and mixing; the water content is controlled at 35-55%.

[0041] Other parameters are the same as in Example 1. Through the above steps, the temperature of the pig house can be raised by using the heat generated by the fermentation of pig manure. In this example, when the ambient temperature is zero, the temperature inside the pi...

Embodiment 3

[0043] A method for generating heat by fermenting pig manure, comprising the following steps:

[0044] 1. Mix 4900 kg of pig manure, 4900 kg of sawdust, 3000 kg of rice bran powder and 1.1 kg of fermented strains in parts by weight, add water and heat-preserve and ferment to obtain the original bacteria; the water content is controlled at 40-50%.

[0045] In the fermented strains, the content of thermophilic coprophagous by weight is 70%.

[0046]In the fermented strains, the content of anaerobic and concurrently anaerobic thermophilic bacteria is 45% by weight.

[0047] 2. Put 11000kg of pig manure in parts by weight, 11000kg of sawdust and 1000kg of original bacteria into the fermentation bed in the piggery after mixing with water; the water content is controlled at 35-55%.

[0048] Other parameters are the same as in Example 1. Through the above steps, the temperature of the pig house can be raised by using the heat generated by the fermentation of pig manure. When the a...

Abstract

The invention relates to a method for generating heat through fermentation of pig manure. The method comprises the following steps: 1, mixing 4500-5200 parts of pig manure, 4500-5200 parts of saw dust, 1800-4200 parts of bran powder and 0.7-1.5 parts of fermented culture in parts by weight and then adding water for heat preservation fermentation to obtain original bacteria; 2, mixing 8-12 parts of pig manure, 8-12 parts of saw dust and 1 part of original bacteria in parts by weight with water and then putting on a fermentation bed inside a hog house for fermentation. Heat is generated through the fermentation of pig manure through the above steps so that the hog house is warmed. With the fermentation twice, anaerobic fermentation is combined with aerobic fermentation, and the put amount of culture is effectively reduced while the heated generated through the fermentation is utilized in the first anaerobic fermentation. The heat value generated during the fermentation is further increased by increasing the content of high-temperature coprophil.

Description

technical field [0001] The invention relates to the field of deep processing of poultry manure, in particular to a method for generating heat by fermenting pig manure. Background technique [0002] Strain fermentation refers to the process of using strains to transform raw materials into products required by human beings through specific metabolic pathways under suitable conditions. The level of strain fermentation production mainly depends on the genetic characteristics and culture conditions of the strain itself. Many large-scale pig farms have been established in our country, and a large amount of pig manure will be produced in the pig farms. Based on the principles of resource reuse and environmental protection, the present invention will use these discarded pig manures for fermentation, and use the waste produced during the fermentation process. The heat heats the pig house. [0003] Since the production technology of fermentation strains is mostly in the hands of for...
