Problems solved by technology

According to reports, the breeding waste produced in my country every year can reach 3.8 billion tons, and the comprehensive utilization rate is less than 60%, which not only seriously pollutes the environment, but also endangers the health of humans and animals to a certain extent.
At present, the treatment of livestock and poultry manure mainly adopts the treatment method of composting and fermentation, and the fermentation of composting mainly uses fermentation pits for fermentation. The existing treatment methods have the problem of slow fermentation speed

Embodiment Construction

[0023] The present invention will be further described in conjunction with embodiment now.

[0024] A method for treating poultry manure, comprising the steps of:

[0025] S1, crushing the straw to 8-20 mm;

[0026] S2. Adjust the C / N of the compost material to 25-30;

[0027] S3, adding livestock and poultry manure, straw and compost materials into the fermentation tank, and adding biogas slurry;

[0028] S4. Adjust the moisture content of the material in the fermenter to make the moisture content 55-65%, and adjust the pH to 7.5-8.5 at the same time;

[0029] S5. Close the fermenter for fermentation, the stirring speed is 30-50 rpm, and air is introduced for composting and fermentation.

[0030] Increase the fermentation speed by adjusting various parameters, and ensure the stable progress of fermentation by stirring and feeding air.

[0031] The weight of biogas slurry is 5-8% of livestock and poultry manure.

[0032] Biogas slurry provides amino acids, auxin and miner...

Abstract

The invention relates to a manure treatment method, in particular to a livestock and poultry manure treatment method which comprises the following steps: S1, crushing straws to 8-20mm; S2, adjusting the C / N of a compost material to be 25-30; S3, adding livestock and poultry manure, straw and the compost material into a fermentation tank, and adding biogas slurry; S4, adjusting the water content ofthe material in a fermentation tank to 55-65%, and adjusting the pH value to 7.5-8.5; and S5, closing the fermentation tank for fermentation at a stirring speed of 30-50 rpm, and introducing air forcompost fermentation. According to the livestock and poultry manure treatment method provided by the invention, the fermentation speed is effectively increased through various measures.

Description

technical field [0001] The invention relates to a treatment method for manure, in particular to a treatment method for livestock and poultry manure. Background technique [0002] In recent years, with the development of the livestock and poultry breeding industry, a large amount of waste has been generated in the process of livestock and poultry breeding. According to reports, the breeding waste produced in my country every year can reach 3.8 billion tons, and the comprehensive utilization rate is less than 60%, which not only seriously pollutes the environment, but also endangers the health of humans and animals to a certain extent. At present, the treatment of livestock and poultry manure mainly adopts the treatment method of composting and fermentation, and the fermentation of composting mainly adopts the fermentation pit for fermentation. The existing treatment method has the problem of slow fermentation speed. Contents of the invention [0003] In order to solve the ...
