Abstract

The invention relates to a method for composting dead poultry and livestock, and belongs to the technical field of harmless treatment of dead poultry and livestock. The present invention processes dead poultry and livestock through stacking, composting in the first stage, stirring, and composting in the second stage. Compared with methods such as incineration and deep burial, the invention has simple equipment, easy operation, high biological safety, and little environmental pollution , and compost products can be used as fertilizers, which not only realize harmless treatment but also realize resource utilization of waste pollutants. It is a good method of dead livestock and poultry treatment, which reduces environmental pollution and harm to humans.

Description

technical field [0001] The invention relates to a method for treating dead poultry and livestock, more specifically, the invention relates to a method for composting dead poultry and livestock, and belongs to the technical field of harmless treatment of dead poultry and livestock in the breeding industry. Background technique [0002] At present, the dead livestock and poultry processing methods in the breeding industry mainly include deep burial, incineration, and industrial oil extraction. Deep burial will pollute the soil and groundwater; incineration costs are high and pollute the atmosphere; oil extraction has low biological safety, and pathogenic microorganisms are easy to spread during transportation, so dead livestock are composted to turn waste into treasure The method is adopted by more and more farming enterprises. [0003] On September 22, 2010, the State Intellectual Property Office published an invention patent with the publication number CN101838166A titled "...
