Background
In rural pastoral areas, cattle raising is the most important economic source for people, but the pollution of cow dung to the environment and the comprehensive utilization of cow dung are the subjects of continuous research of people. Generally, the daily cow dung generated by 1 cow is 5% -6% of the weight of the cow. For example, 1 head of beef cattle with the weight of 450 kg can produce 23 kg of excrement in a cowshed every day, and the cattle excrement contains a plurality of nutrient components, wherein the nutrient components comprise 3-4% of nitrogen, 1-2% of phosphorus (P2O 5), 1.5-3% of potassium, 0.6% of calcium, 0.02% of iron, 0.5% of magnesium and 0.4% of sulfur. Cow dung has an environmental impact because the nutrients in the feed are not completely absorbed by the digestive tract of the cow, and these nutrients and energy support the eggs and malodorous microorganisms and consume oxygen in the water. The formed cow dung pollutes clean water sources, air and soil, and breeds a great amount of pests such as flies.
The pollution of cow dung to water sources mainly consumes dissolved oxygen in water, so that fishes and plants in the water die due to oxygen deficiency.
1 head of 450 kg of cow dung produced in 1 day can consume 91 m3 of oxygen in water. Therefore, the destruction of the water source by cow dung is very serious.

After the cow dung is subjected to the manure of the reactor, however, the cow dung can provide good organic fertilizer for gardening.
The main components of the cow dung are crude fiber, protein, sugar, fat and other substances which are easily decomposed in the environment, and can be diluted and diffused by the land to be gradually purified. The organic fertilizer is produced by taking the cow dung as the raw material, thereby not only protecting the surrounding environment of a cow farm and surface water and underground water from being polluted, but also realizing the reutilization and harmless treatment of wastes and changing wastes into valuables,
the cow dung is easy to store and convenient to transport after being made into animal manure, and is an organic fertilizer suitable for various crops, flowers and fruit trees. At present, 1000 cattle farms fattening cattle in a slaughter year can produce more than 1300 t of organic compound fertilizer, and the output value reaches 260000 yuan in terms of 200 yuan per ton.
The existing cow dung fermentation tank has poor heat insulation performance, uneven temperature and difficult control, and insufficient oxygen supply causes poor fermentation effect, continuous production can not be realized, and the fermentation requirement of a large amount of organic fertilizers can not be met.
In order to prevent the cow dung from polluting water, land or atmosphere, the fermentation effect is good, residual nutrient substances in the cow dung are effectively utilized, and the design of the cow dung fermentation machine which has no pollution to the environment, saves energy and can continuously produce is very necessary.
