Poultry waste pollution and treatment methods

 With the development of social economy and the improvement of people's living standards, the proportion of animal foods in people's diet structure has increased. China is a big country for livestock and poultry breeding. With the emergence of large-scale livestock and poultry farms, livestock manure has become a prominent problem of environmental pollution. If we don't dispose of these wastes, they will pollute the environment in the following ways:

1. Harmful gas pollution: The agricultural production process is an important source of greenhouse gas emissions. Its emissions mainly come from rice fields and other fertilized farmland, livestock and poultry manure, etc., and animal manure will be produced during the process of stacking and storage. The malodorous gas, which contains harmful components such as ammonia, sulfides and methane, pollutes the surrounding air and seriously affects the air quality. These odorous substances can irritate the human nervous system, poisoning the respiratory center, and also detrimental to the growth of livestock and poultry, reducing their production capacity.

2. Contamination of pathogenic microorganisms: Untreated livestock and poultry excrement contains a large number of pathogenic microorganisms, parasites and eggs, which can survive and multiply in the soil, expand the source of infection, and cause human and animal infectious diseases and parasites. Spread.

3. Nitrogen and phosphorus pollution: Livestock and poultry manure contain a large amount of inorganic nitrogen, phosphorus and nitrogen-containing organic matter and phosphorus-containing organic matter. They will be decomposed into harmful substances by aerobic state downloading nitrifying bacteria, and then infiltrated into rivers and lakes by infiltration or rain, causing pollution of groundwater sources and surface water sources, endangering human health.

4. Heavy metal pollution: Adding trace element additives such as copper, zinc, iron and arsenic to animal feed, which promotes animal growth or regulates physiology and metabolism, but these metal elements are directly digested and absorbed by animals, and more It is excreted through the feces. Their transmission through the food chain also affects human health.

The current popular practice is to process these livestock wastes into organic fertilizers through organic fertilizer equipment. After the organic fertilizer manufacturing process with organic fertilizer fermentation equipment and organic fertilizer granulator machine as the main equipment, the livestock and poultry manure becomes popular bio-organic fertilizer product on the market.
