Preparation method of bio-organic fertilizers produced by diseased and death livestock and poultry

Abstract

The invention relates to a preparation method of bio-organic fertilizers produced by diseased and death livestock and poultry. The diseased and death livestock and poultry are used as major raw materials; the raw materials enter a crushing machine by a feeding system; the crushing machine is used for performing sealed crushing on the raw materials; the crushed raw materials are subjected to sterilization and disinfection treatment; the raw materials subjected to sterilization and disinfection are subjected to bacterium addition and auxiliary fermentation treatment; then, auxiliary materials such as strains and saw dust are fed into the crushing machine; after the uniform stirring, fermented materials are obtained. The fermented materials are discharged through a discharging device and areconveyed to a finished product producing warehouse through a conveying belt; aerobic fermentation is performed; the fermented products are subjected to drying treatment to obtain biological organic fertilizers. The method has the advantages that the diseased and death livestock and poultry bodies and animal processing waste are subjected to two-step harmless treatment through high-temperature steaming and boiling and high-temperature aerobic fermentation to be converted into safe and high-quality bio-organic fertilizers; the processing process is simple; the cost is low; secondary pollution isnot generated; the pollution of diseased and death livestock and poultry on the environment can be effectively eliminated; the safe and high-quality bio-organic fertilizers can be obtained.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a preparation method for producing bio-organic fertilizer by using sick and dead livestock and poultry. Background technique [0002] The development of China's aquaculture industry is still dominated by farmers' breeding. Farmers' breeding involves thousands of households, and the level of breeding technology is uneven. Due to poor management and weak awareness of epidemic prevention, it is very easy to cause the death of animals from diseases and dead animals. It poses a serious threat to the development of the livestock and poultry breeding industry. [0003] According to national requirements, dead animals should be treated harmlessly, but for most farmers, it takes a lot of time and money to deal with dead animals. A considerable number of them chose to throw them away at will, and some even sold them secretly, which brought huge hidden dangers to huma...

AI Technical Summary

Problems solved by technology

The commonly used chemical production method has the following problems: it is easy to form stench and waste water during the treatment process, especially in the transportation road, stacking in warehouse and cooking process, and the stench and waste water produced often cause environmental pollution to adjacent areas. Pollution; although the above problems have been solved in the application number 201310341863.0, the treatment process is complex, the cost is high, and the fermentation material is uneven in particle size, color inhomogeneity, and has peculiar smell.
