The rapid development of animal husbandry has also generated a large amount of livestock and poultry manure. Currently, livestock and poultry manure has become the primary source of pollution in agriculture. The impact of livestock and poultry manure on the environment is mainly reflected in the harmful gases generated by the accumulation of manure, which can pollute the air, cause fecal sewage to enter the ground, worsen water quality, and endanger human health.
With the continuous improvement of the scale of livestock breeding industry, the traditional inefficient fecal treatment method cannot meet the requirements of farms or cooperatives, so the research on efficient, rapid and harmless treatment technology and key equipment of livestock and poultry feces is urgent. The harmless equipment of livestock and poultry can not only help large-scale breeding enterprises to complete the effective treatment of feces in time, but also prevent the secondary pollution of feces to the agricultural environment and the surrounding environment of farms, Eliminating the epidemic prevention hazards of manure in breeding areas, and at the same time, the harmless treated livestock and poultry manure can also be directly used as the main raw material for professional organic fertilizer processing enterprises to process organic fertilizer. This is of great significance for increasing the income of breeding enterprises, reducing the cost of organic fertilizer processing, promoting the sustainable development of agriculture and rural economy, and developing circular agriculture.
