In recent years, pollution disputes arising from the discharge of feces, urine, and sewage from livestock farms have been on the rise. After the new generation of environmentally friendly organic fertilizer equipment has achieved certain control over industrial pollution, the treatment of livestock and poultry farm manure has become a key focus of current pollution prevention and control. The pollution of large-scale livestock and poultry farming is not only a problem that affects its development, but also an important issue that affects its survival. Therefore, promoting the use of organic fertilizer equipment for livestock manure to solve pollution in livestock farms has become an urgent task for livestock farms. These wastewater rich in nitrogen and phosphorus are continuously discharged into the water body for a long time, producing toxic substances during the metabolic process, leading to the deterioration of the water body. If livestock and poultry manure is not treated according to the technical standards of harmless organic fertilizer equipment, it will ultimately lead to the spread and development of infectious diseases and parasitic insect eggs in livestock and poultry, affecting the health of livestock and humans.

There are many raw materials for the production of small cattle and sheep manure compound fertilizer production lines, which can be specifically divided into the following categories: 1. Agricultural waste: such as straw, soybean meal, cotton meal, etc. 2. Animal manure: such as chicken manure, pig manure, cow manure, sheep manure, horse manure, and rabbit manure; 3. Industrial waste: such as vinegar residue, wine residue, sugar residue, cassava residue, furfural residue, etc; 4. Household waste: such as food and kitchen waste; 5. Urban sludge: such as sewage sludge, river sludge, etc.

The small-scale cattle and sheep manure compound fertilizer production line mainly consists of a fermentation system, a drying system, a deodorization and dust removal system, a crushing system, a batching system, a mixing system, a granulation system, a cooling and drying system, a screening system, and a finished product packaging system.

The characteristics of the small-scale cattle and sheep manure compound fertilizer production line are advanced technology, scientific and reasonable, compact process layout, energy conservation and consumption reduction, stable operation, no three emissions, reliable operation, wide adaptability of raw materials, and convenient maintenance. Adapting to various ratios of organic compound fertilizers, bio organic fertilizers, urban sludge, household waste organic fertilizers, etc., it fills the domestic gap and ranks at the leading level in China. It is a promotion project of national environmental protection practical technology, and chicken manure is rich in organic matter, which can provide the nutrients required for crop growth and improve soil fertility.
