First, the current status of cow dung utilization in China The dairy industry in the foreign dairy industry drinks milk from large ranches. The ranching of China's dairy industry is still in its infancy. With the improvement of peopleâ€™s living standards and changes in consumer attitudes, consumers are concerned about the quality and safety of milk. The requirements have gradually increased, and each dairy company has cooperated or established itself with large-scale farms in order to ensure the quality and safety of raw milk. With the rapid development of the cattle industry, fecal contamination has become a major problem. According to relevant data, in some places, the environmental pollution of cow dung has exceeded the total amount of industrial pollution, and some even as high as 2 times. A cow produces more than 7 tons of feces every year. Due to the general lack of attention paid to the treatment of cow dung in various places, some farms of medium or lower size have basically no cattle dung processing facilities. There is no cow manure treatment facilities in the district, the ranch cow dung processing methods are mainly scattered indiscriminately put, a small part of the organic fertilizer or directly on the ground for fermentation, cow dung everywhere indiscriminately after the dumping, every summer, bad smell, serious Pollution of the environment, dilute into rivers after rain, after rain, not only adversely affect the normal life and production of the surrounding residents, but at the same time cow dung is the source of breeding of a variety of bacterial pathogens, has a serious impact on the breeding groups. In addition, the use of raw cow dung as a fertilizer on the ground, it generates heat, consumes oxygen in the soil, resulting in the burning of root burning seedlings, but also play a role in transmission of parasite eggs, pathogenic microorganisms. Dairy industry throughout the country has developed rapidly in recent years, and some areas are even local pillar industries. However, with the increase in the number of cows, a large number of cow dung has also become a major source of pollution affecting the local environment. How to make good use of cow dung is a problem that needs to be solved urgently. Therefore, the non-pollution treatment of cow dung is very important. Second, the current status of non-polluting cow dung processing methods Currently, there are many non-polluting cow dung processing methods, commonly used methods are: 1, the cow dung urine water after microbial fermentation into organic fertilizer, used to plant grass back to the field; 2 Biochemical treatment, such as biogas power generation, biogas production, biogas residue and other by-products can also be used for fish after dilution; 3, the use of oxidative degradation technology to convert most of the organic matter of cow dung into water-soluble organic acids (Including fulvic acid, amino acids, sugar acids, ribonucleic acids, etc.), known as "amino-fulvic acid", can be used as a high-efficiency plant growth promoter, and can also be used to formulate multi-element foliar spray fertilizers, seed soaking agents, and seedlings. Agent and so on. The above three types of non-contaminated cow dung treatment methods are used for large-scale investment, large-scale land occupation, and high technical requirements, and are not suitable for farms of medium or lower size. After many visits and investigations, it was found that the use of physical methods to dry fresh cow dung into cow dung (can be used as fuel, breeding of Agaricus bisporus) both cow dung drying pollution-free treatment, with less capital investment, easy to grasp, applicable The advantages such as strong sex have great promotion potential. Now we introduce cow dung drying technology as follows. 1, the principle of cow dung drying technology can be up to 70% - 80% of the water content of the manure once dried directly to 13% of the safe storage of water, the entire process in a closed system to reduce the drying process of environmental pollution . Equipment composition: It consists of heat source, feeding machine, feeder, rotary drum, discharge machine, material crushing device, induced draft fan, unloader and distribution cabinet.
