Method for preparing fertilizer from animal carcasses by harmless treatment

Abstract

The invention discloses a method for preparing fertilizer from animal carcasses by harmless treatment. The method comprises steps as follows: crushing carcass parts by a mechanical device; performingprimary sterilization by microwaves; rupturing membranes on the basis of an osmotic pressure principle; adopting targeted enzymolysis to rupture the membranes according to different cells and performing secondary sterilization; performing enzymolysis on trephones in the cells to form usable nutrients; eliminating toxins; preparing the fertilizer. The method is non-toxic, harmless, free of stink, high in recycling and reusing value and good in use ratio.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for harmlessly treating animal corpses into fertilizers. Background technique [0002] At present, the conventional landfill treatment of large animal carcasses is likely to cause soil, air and water pollution. At the same time, animal carcasses often carry a variety of germs, which can easily cause the spread and spread of diseases, and also occupy land and cost a lot. With the increasingly serious problem of environmental pollution from aquaculture waste, the specific manifestations are: water pollution, which leads to the decrease of dissolved oxygen in the water body, the decrease of transparency, and the deterioration of water quality; air pollution, odorous gas, which is harmful to the environment; The increase of factors will cause mosquitoes and flies, which will easily lead to "zoonotic" infectious diseases; endanger the growth of crops, and th...

[0002] At present, the conventional landfill treatment of large animal carcasses is likely to cause soil, air and water pollution

At the same time, animal carcasses often carry a variety of germs, which can easily cause the spread and spread of diseases, and also occupy land and cost a lot of money.

With the increasingly serious problem of environmental pollution from aquaculture waste, the specific manifestations are: water pollution, which leads to the decrease of dissolved oxygen in the water body, the decrease of transparency, and the deterioration of water quality; air pollution, odorous gas, which is harmful to the environment; The increase of factors will lead to the occurrence of mosquitoes and flies, which will easily lead to "zoonous" infectious diseases; endanger the growth of crops, and the sewage generated by the littering of sick and dead livestock and poultry will inhibit the growth of rice roots.

Some farmers will abandon them to the river, so for a period of time there were dead pigs drifting in the river, causing pollution and causing bad social impact

[0003] But in fact, animal carcasses are extremely nutritious, which is pure waste, but because the protein in the carcasses has deteriorated and a variety of stable harmful substances remain, they can no longer be used as feed, and can only be treated as plant fertilizers
