Embodiment 1

[0051] The processing method of cow dung may further comprise the steps:

[0052] (1) Pre-dehydration: placing untreated cow dung in a fermenter to remove moisture until the moisture percentage of cow dung is 60%;

[0053] (2) Pre-fermentation: After adding microbial inoculum to cow dung, ferment at 35°C for 7h; said microbial inoculum is composed of Bacillus mycoides and Bacillus subtilis; 5% of mass;

[0054] (3) Batching: add in the fermenter the adjuvant that is made up of 10 parts of Chinese medicine dregs of mass parts, 5 parts of lime, 20 parts of bacterium chaff after mixing; , Gynostemma pentaphyllum, peppermint, water calamus, cassia bark, rhubarb; the mass ratio of the cow dung and auxiliary materials is 10:1;

[0055] (5) Main fermentation: Add the fermented bacteria consisting of cellulose-degrading bacteria, xylan-degrading bacteria, and EM bacteria at a ratio of 1:2:9 to the fermenter and continue at 45°C Lower fermentation for 5h; the addition of the ferment...

Embodiment 2

[0058] The processing method of cow dung may further comprise the steps:

[0059] (1) Pre-dehydration: untreated cow dung is placed in a fermenter to remove moisture until the moisture percentage of cow dung is 50%;

[0060] (2) Pre-fermentation: After adding microbial inoculum to cow dung, ferment at 40°C for 5h; the microbial inoculum is composed of Bacillus mycoides and Bacillus subtilis; 5% of mass;

[0061] (3) Batching: add in the fermenter the adjuvant that is made up of 10 parts of Chinese medicine dregs of mass parts, 5 parts of lime, 20 parts of bacterium chaff after mixing; , Gynostemma pentaphyllum, peppermint, water calamus, cassia bark, rhubarb; the mass ratio of the cow dung and auxiliary materials is 10:1;

[0062] (5) Main fermentation: Add the fermented bacteria consisting of cellulose-degrading bacteria, xylan-degrading bacteria, and EM bacteria at a ratio of 1:5:5 to the fermenter and continue at 50°C Lower fermentation for 3h; the addition of the fermen...

Embodiment 3

[0065] The processing method of cow dung may further comprise the steps:

[0066] (1) Pre-dehydration: untreated cow dung is placed in a fermenter to remove moisture until the moisture percentage of cow dung is 55%;

[0067] (2) Pre-fermentation: After adding microbial inoculum to cow dung, ferment at 38°C for 6h; said microbial inoculum is composed of Bacillus mycoides and Bacillus subtilis; 3% of mass;

[0068] (3) Batching: add in the fermenter the adjuvant that is made up of 12 parts of Chinese medicine dregs, 3 parts of lime, 25 parts of bacterium bran of mass parts and mix and stir evenly; , Gynostemma pentaphyllum, peppermint, water calamus, cassia bark, rhubarb; the mass ratio of the cow dung and auxiliary materials is 8:1;

[0069] (5) Main fermentation: Add the fermented bacteria consisting of cellulose-degrading bacteria, xylan-degrading bacteria, and EM bacteria at a ratio of 1:3:8 to the fermenter, and continue at 48°C Lower fermentation for 4h; the addition of...

Abstract

The invention discloses a cow dung treatment method. The cow dung treatment method comprises the following steps: (1) pre-dehydrating: dehydrating cow dung until the moisture percentage content of thecow dung is 50 percent to 60 percent; (2) pre-fermenting: adding bacillus mycoides and bacillus subtilis into the cow dung and then pre-fermenting; (3) preparing materials: adding an auxiliary material composed of traditional Chinese medicine dreg, lime and germ bran into a fermentation tank and mixing and stirring uniformly; (5) carrying out main fermentation: adding a fermentation bacterium agent composed of cellulose degradation bacteria, xylan degradation bacteria and EM bacteria into the fermentation tank and carrying out the main fermentation; (6) drying: drying the cow dung by utilizing infrared rays until the moisture percentage content of the cow dung is 5 percent to 10 percent. A product obtained by the cow dung treatment method disclosed by the invention can be directly used for cultivating edible mushrooms; the treatment method is simple and convenient, high in efficiency and strong in practicability.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a method for treating cow dung. Background technique [0002] Cow dung is rich in nutritional value, which is rich in crude protein, crude fat, crude fiber, crude ash, ammonia-free extract, and rich in calcium, phosphorus, vitamin A1, B1, B2, B12, vitamin C, Vitamin K, folic acid, pantothenic acid, choline, lutein. Among them, the content of crude protein and crude fiber in cow dung is relatively high. Cow dung has many uses and is of high value, such as fermenting cow dung to make organic fertilizer, fermenting cow dung to raise pigs, and using cow dung as a culture substrate or seedling soil for edible fungi, or using Cow dung is used to generate electricity or domestic gas after being fermented in a biogas digester. [0003] Because cow dung also contains grass seeds, weeds will grow when used as farmyard manure, so many growers are unwilling to use cow dung as far...
