What is the use and value of cow dung? What is the most profitable way to handle it?

As the name implies, cow dung is the excrement of cattle, that is, feces. It is called "Jiuwa" in Tibetan and has a variety of uses, such as as fuel. Let's learn about the use and value of cow dung. What is the most profitable way to handle it?

What is the use and value of cow dung?

1. Cow dung can be used as fuel: in Xizang area of China, cow dung has been used as a fuel for cooking tea for thousands of years. This not only solves the problem of cow dung but also provides fuel for people, which can be said to kill two birds with one stone.

two。 Cow dung can be used as fertilizer for stacking fermentation: cow dung not only takes up space but also smells bad, but if used for stacking fermentation, it can be used as organic fertilizer.

3. Cow dung can be fermented as a substitute for coal and biogas to generate electricity: the electricity generated by cow dung fermentation can save 1.2 million yuan a year. In addition, Fengdu County can also develop cow dung sticks and honeycomb coal, which are made of cow dung as fuel with high combustion value. Cow dung honeycomb coal is suppressed with cow dung and coal at the ratio of 4:6, which solves the air pollution caused by honeycomb coal combustion.

4. Cow dung can be used as animal feed: the various nutrients and minerals contained in cow dung are still very suitable to be used as feed after treatment.

5. Cow dung can be used as mushroom material to grow fungi: dehydrated and fermented cow dung plus cotton shell, corncob and so on can be used as mushroom materials for cultivation of bisporus, mushroom and other fungi. When the local demand for Pleurotus ostreatus is large, it can be planted in a small amount.

6. Cow dung can be used as a raw material for raising earthworms: earthworm meal is a good feed additive and has a higher protein content than fish meal. At present, the price of fish meal is more than 20000 yuan per ton. If earthworm meal is developed on a large scale, the benefit will be considerable. The examination and analysis of Beijing Institute of Nutrition sources shows that protease preparations, microbial preparations and feed additives made from earthworm powder are natural health agents for animals. Feeding them to livestock and poultry can significantly promote animal growth and make animals rarely infected with diseases. All kinds of special fertilizers produced with earthworm manure as the main raw material can not only have high fertilizer efficiency, but also inhibit the spread of diseases and insect pests of which crops, but also improve soil temperature, water and fertilizer conservation.

7. The image of cow dung can also be used as a toy, because the homophonic "Niufen" of cow dung has a good meaning, so it is sold very well as a toy.

Second, how to deal with cow dung in order to make the most money?

1. Drying cow dung as heating fuel: the heat of cow dung is high, there is less burning smoke, and it is basically smokeless, so cow dung can be concentrated and dried and sold to farmers to burn Kang or contact some fixed boiler manufacturers.

two。 Ferment cow dung into biogas digester: concentrate cow dung to ferment biogas digester to convert it into electricity, and in the process of biogas production, it can also kill pathogenic microorganisms and parasite eggs in cow dung, so that it will not cause secondary pollution to the environment, and the fermentation residue can also be used as fertilizer to kill more than one stone.

3. Using cow dung as feed for chickens and fish: the processed cow dung and bran are piled up and fermented to breed earthworms as feed for animals such as chicken and fish, so as to recycle organic matter, improve income and do not cause environmental pollution.

4. Use cow dung to grow mushrooms: mix cow dung with rice straw to ferment, and then make substrates to grow mushrooms and other fungi. there are many techniques and methods of how to use cow dung to grow mushrooms on the Internet, so as to realize the high-value use of cow dung.

5. Processing cow dung into organic fertilizer: cow dung can be processed into organic fertilizer, which is mainly sold to ecological plantations, orchards, flower plantations and so on.

How much is the price of cow dung per ton?

1. The price of ordinary cow dung without processing and treatment is about 100 yuan per ton. You can ask the local cattle farm for detailed prices.

two。 If it is dehydrated and deeply processed cow dung can be sold for 1,000 yuan per ton.

Fourth, how is cow dung processed into fertilizer?

1. First, the cow dung should be dried or drained so that the moisture content of the cow dung is controlled below 85%, and then the powdered straw is added to the cow dung. The ratio of cow dung to straw powder is 7:3, so that the carbon ratio of raw materials (cow dung) excipients (straw powder) is 23-28, and the water content is 52% 68%.

two。 Then add organic fertilizer fermentation ripening agent. After mixing the raw materials, auxiliary materials and bacterial agents, the fermentation can be carried out on the heap. The requirement of the upper pile is to stack the mixture on the fermentation site into a trapezoidal stack with a width of about 1.8-3 meters and a width of 0.8-1 meter and a height of 1-1.5 meters. The distance between the stack and the stack is 0.5 meters. (the width above is only a reference value, which is based on the actual situation.)

3. After it is done, the temperature will rise above 60 ℃ within 24-48 hours. Keep the temperature for 48 hours and start to turn over. When turning the pile, be sure to turn evenly and thoroughly, and turn the low-level special materials into the middle and upper part of the pile as far as possible, so as to fully mature.

4. After turning the pile for the first time, the pile will be turned once a week. If the temperature exceeds 70 ℃, the pile must be turned immediately, otherwise a large number of beneficial microorganisms and fermentative bacteria will be killed, which is not conducive to fermentation and ripening.
