Description

Technical Field

[0001] The present invention relates to the technical field of feces processing, and in particular to a solid feces fermentation, drying and crushing system and method. Background Art

[0002] At present, there are two main types of fertilizers used for crops, one is farmyard manure and the other is chemical fertilizer. Farmyard manure plays a certain role in improving soil, increasing fertility and crop yields, but its disadvantages are low nutrient content, low quick-acting property, containing pathogens, parasites, weed seeds, polluting soil and atmosphere, and more importantly, it is impossible to organize large-scale commercial production and enter the circulation field. Although chemical fertilizers have high nutrient content and quick fertilizer effect, with the large-scale application of chemical fertilizers, its shortcomings are obviously exposed, causing soil compaction, acid-base imbalance, reduction of soil organic matter, and decline in fertility. It pollutes the soil, atmosphere, and groundwater to varying degrees, resulting in weak root systems of crops, weak photosynthesis, disordered ecological cycles, increased content of carcinogenic substances such as nitrite in plants, reduced quality of agricultural products, and problems with food quality and safety. It will eventually degrade the physical, chemical and biological properties of the soil, and farmland will become a chemical land that cannot be produced.

[0003] With the rapid expansion of my country's livestock and poultry breeding industry, a large number of large, medium and small livestock and poultry farms have been built in rural areas. Some areas have also established specialized livestock and poultry breeding communities, specialized villages and specialized households, resulting in a large amount of livestock and poultry manure. At present, rural areas mainly adopt a decentralized and multi-point treatment of livestock and poultry manure, which is difficult to centrally treat. Due to the lack of comprehensive management measures, livestock and poultry manure is discharged into the natural environment without any treatment, causing a foul odor and flying mosquitoes and flies. The ecological environment is under tremendous pressure and is seriously polluted. At the same time, it is easy to cause the spread of infectious diseases such as avian influenza, which harms people's health.

[0004] Bio-organic fertilizer is a fully nutritious fertilizer based on organic matter, which is beneficial to balance and increase the nutrient content of soil, repair and improve soil structure and soil micro-ecosystem. Therefore, adopting reasonable livestock and poultry manure treatment methods to convert livestock and poultry manure into bio-organic fertilizer, turning waste into treasure and protecting the environment has become a key technology that needs to be urgently solved in the development of the current livestock and poultry breeding industry.
