Method for producing biological organic fertilizer by using livestock and poultry died from diseases

Abstract

The invention relates to a method for producing a biological organic fertilizer by using livestock and poultry died from diseases. According to the invention, the dead livestock and poultry are adopted as main raw materials, transported to a chemical preparation factory, and centralized and stacked at a raw material zone; the raw materials are cut and minced by using a mincing machine; a functional biological fermentation microorganism agent is added into the minced material for softening; the softened material is subjected to high-temperature processing in a high-temperature steaming device, such that a crude material is prepared; the crude material is stir-fried in a stir-frying stirring machine; and the stir-fried material is processed by an oil-bone separator, such that oil, oil slag, and meat-bone meal semi-finished product are produced. The biological organic fertilizer production process comprises pretreatment, tempering, inoculation, fermentation, drying and dehydration, and crushing and sieving. According to the invention, bodies of livestock and poultry died from diseases and animal processing waste are subjected to high-temperature steaming and high-temperature aerobic fermentation two-step harmless treatments, such that the waste is turned into safe and high-quality biological organic fertilizer. The processing process is simple, cost is low, no secondary pollution is caused, pollution caused by livestock and poultry died from diseases can be effectively eliminated, and safe and high-quality biological organic fertilizer can be obtained.

Description

technical field [0001] The invention relates to a production method of bio-organic fertilizer, in particular to a method for producing bio-organic fertilizer by using harmless treated dead livestock and poultry as raw materials. Background technique [0002] With the improvement of management technology and equipment, animal husbandry production has gradually changed from an early sideline operation to specialized intensive breeding, and the amount of breeding has continued to increase. During the breeding process, some animals die due to climate and environmental factors or infectious diseases. The resulting animal carcasses or the discarded viscera, skin, bones or hooves from slaughtering need to be followed up to avoid impact on the environment or animals. . Commonly used disposal methods include landfill, incineration, and chemical production. The landfill method is the most common final disposal method, but there are problems such as difficulty in choosing a landfill ...

AI Technical Summary

Problems solved by technology

The landfill method is the most common final disposal method, but there are problems such as difficulty in choosing a landfill location, penetration of landfill fluid, groundwater pollution, and high cost; the incineration method converts waste into residues without combustible substances and gas emissions by burning them. Into the atmosphere, its residues and non-combustible substances need to be treated separately, and the discharged gas must comply with environmental protection regulations, otherwise it will easily cause secondary pollution and other problems, the incinerator facilities and operating costs are high, and the economic benefits are low; The method is to process animal carcasses or waste such as viscera, skin, bones or hooves, and decompose them into reusable resources such as oil and protein.

The commonly used chemical production method often has the following problems: it is easy to form odor and waste water during the treatment process, especially in the transportation road, raw material storage area and cooking process, and the generated stench and waste water often cause damage to neighboring areas environmental pollution
