Problems solved by technology

[0005] (1) There are many related equipment for biogas treatment, and the cost is expensive, and the daily management and maintenance work is cumbersome;
[0006] (2) In order to achieve the purpose of cleaning the manure in the pen, it is necessary to rely on a large amount of manpower or expensive mechanical equipment;
[0007] (3) Biogas treatment needs to consume a lot of fresh water resources and land resources;
[0008] (4) The proliferation of anaerobic microorganisms is slow, so the time period of biogas treatment is long, and it cannot cope with the large amount of livestock and poultry manure produced every day;
[0009] (5) In general, the quality of effluent after biogas treatment cannot directly meet the requirements of discharge standards, and further treatment is required, so corresponding treatment equipment needs to be added;
[0010] (6) The methane-based methane gas produced in the biogas treatment process is a flammable and explosive gas, which has potential safety hazards;
[0011] (7) Strict requirements on temperature, when the temperature of wastewater is low, it will have a great impact on the treatment effect, and the management operation is more complicated;
[0012] (8) Unable to solve the odor in the pen, affecting the living environment of the surrounding residents

preparation example Construction

[0050] Step 1, preparation of mixed strains

[0051] According to a certain ratio of the number of bacteria, take an appropriate amount of Bacillus subtilis, Bacillus pumilus, Bacillus cereus, Bacillus licheniformis, Acinetobacter ruckeri and Alcaligenes faecalis to prepare the required mixed strains, the specific The preparation process is:

[0052] (1) Slope culture of strains:

[0053] Bacillus subtilis, Bacillus pumilus, Bacillus cereus, Bacillus licheniformis, Acinetobacter ruckeri and Alcaligenes faecalis in cryopreservation tubes were respectively activated on a slant, and then placed in suitable petri dishes for Purify to obtain Bacillus subtilis, Bacillus pumilus, Bacillus cereus, Bacillus licheniformis, Acinetobacter ruckeri and Alcaligenes faecalis for later use.

[0054] In step (1), the specific steps for the activation of Bacillus subtilis in the slant are: use an inoculation loop to inoculate Bacillus subtilis on the sterilized slant medium I, and then cultiva...

Embodiment 1

[0080] A mixed bacterial species for the degradation of livestock and poultry biological manure, which is composed of the following microorganisms: Bacillus subtilis, Bacillus pumilus, Bacillus cereus, Bacillus licheniformis, Acinetobacter ruckerii, Alcaligenes faecalis and microbial metabolic active products , the mixed strain is a yellow liquid, and the range ratio of the bacterial count of each strain is: the colony count of Bacillus subtilis in the mixed strain is 6-3 billion cfu / g, and the colony count of Bacillus pumilus in the mixed strain is 7-3.5 billion cfu / g, the number of colonies of Bacillus cereus in the mixed strains is 6-3.5 billion cfu / g, the number of colonies of Bacillus licheniformis in the mixed strains is 7-3 billion cfu / g, Lu The number of colonies of Acinetobacter faecalis in the mixed strains is 300-1500 million cfu / g, and the number of colonies of Alcaligenes faecalis in the mixed strains is 400-1200 million cfu / g.

Abstract

The invention discloses a livestock manure biodegradation mixed culture, a carrier and a method. The mixed culture mainly comprises bacillus subtilis, bacillus pumilus, bacillus cereus, bacillus licheniformis, acinetobacter lwoffii and alcaligenes faecalis, and is yellow liquid, a bacterial spawn is obtained by mixing and crushing the carrier and the mixed culture, the mixed culture and the livestock manure are mixed for degradation, and a small number of generated residues can be used as organic fertilizer in greening. The livestock manure biodegradation mixed culture, the carrier and the method have the advantages that the livestock manure is emission-free, pollution-free and odourless, the livestock manure biodegradation contains natural antibiotics, the immunity of the livestock can beimproved, constant temperature and stable fermentation can be maintained; a livestock manure biodegradation device or equipment can save land resources, the cost of construction of livestock breeding, labor, energy and the like, the device and the equipment are combined on the basis of the corresponding purposes of the work to achieve the goal of disposing organic matter or degrading organic matter.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry excrement treatment, in particular to a mixed strain, a carrier and a method for degrading livestock and poultry biological excrement. Background technique [0002] In recent years, with the rapid development of intensive breeding industry, how to effectively and economically treat livestock and poultry excrement so as not to pollute the environment has become a top priority for breeding enterprises. [0003] At present, farming enterprises generally use such as figure 1 The biogas engineering technology shown is used to treat the collected livestock and poultry manure. However, objectively speaking, the technical progress of biogas engineering is not obvious, and the processing efficiency is low. In addition, farm pollutants include livestock and poultry manure and housing flushing water. The former has a high concentration, but its amount is only about 1 / 7 of the flushing water. ...
