Description

A high-efficiency anaerobic fermentation device for livestock and poultry manure

technical field

The utility model relates to the field, in particular to a high-efficiency anaerobic fermentation device for livestock and poultry manure.

Background technique

With the rapid development of the breeding industry, some heavy metal elements are widely added to livestock and poultry feed. Most of these heavy metal elements are discharged with livestock and poultry manure. At this time, livestock and poultry manure is fermented and applied to farmland, which will cause soil pollution. Heavy metal pollution.

The removal and purification of heavy metal elements generally adopt biological treatment, that is, the fermentation technology of livestock and poultry manure. Livestock and poultry manure fermentation technology uses the activity of microorganisms to biodecompose and decompose the organic matter in livestock and poultry manure, so that organic waste can be converted into organic fertilizer raw materials. Organic fertilizers can be used for soil improvement, organic vegetable planting, landscaping, etc., and finally realize the harmless utilization of organic waste and protect the environment. When the temperature, moisture, oxygen content and other conditions in the fermenter reach a certain target, these microorganisms multiply and decompose the organic matter contained in the livestock and poultry manure.

For customers, the anaerobic fermentation of livestock and poultry manure is not only for treating manure and avoiding pollution; more importantly, it is to produce standard organic fertilizers and generate profits. To produce a standard organic fertilizer, it is necessary to ensure that the microbial content, organic matter content, and nitrogen, phosphorus, and potassium content of the fermented organic fertilizer meet the national organic fertilizer standards. Taking chicken manure as an example, the fermented moisture of chicken manure is best controlled at about 55%. However, the moisture of fresh chicken manure is mostly more than 70%. At this time, it is necessary to use auxiliary materials to adjust the moisture of chicken manure to 55%. About to meet the moisture requirements of fermentation. According to the national organic fertilizer standard, the total content of NPK (NPK refers to nitrogen, phosphorus, and potassium) must be greater than or equal to 5%, but the original nitrogen, phosphorus, and potassium content in chicken manure cannot reach this index, and then it needs to pass Add auxiliary materials to supplement, so that the organic matter content meets the standards stipulated by the state. Therefore, in order to produce a standard organic fertilizer, it is necessary to adjust the water content by adding auxiliary materials, adjust the carbon-nitrogen ratio in the raw material, increase the organic matter content, enhance the permeability of the material, and increase the oxygen content during chicken manure fermentation.

Mechanical stirring can ensure the mixing uniformity of auxiliary materials and livestock and poultry manure. The mechanical agitation of traditional anaerobic fermentation tanks for livestock and poultry manure has dead angles, and the stirring efficiency is poor, which affects the efficiency of anaerobic fermentation of livestock and poultry manure. In addition, temperature control is also an important factor affecting the efficiency of anaerobic fermentation of livestock and poultry manure. Most of the existing anaerobic fermentation tanks for livestock and poultry manure use electric heating, which can bring high energy consumption and increase the production cost of the enterprise.

To sum up, the existing anaerobic fermentation tanks for livestock and poultry manure have the problems of poor mechanical stirring effect, low anaerobic fermentation efficiency, and high heating energy consumption.
