Innoxious process for treating mainly can reduce following four kinds of methods, promptly buried method, burning method, high temperature and high pressure method and chemical hydrolysis at present.

(1), buried method: in the open air or locality, the epidemic situation spot landfill of digging pit with spoil.Corpse should be away from more than the water source 50m, in the mode of the thick bleaching powder isolation one deck corpse of one deck 3cm-5cm, apart from buried below the 2m of ground.Burying place selection is principle with a morbidity interior soil, and selected place should be as far as possible near the infected zone under landform allows.This method: the one, easy polluted underground water source; The 2nd, because of drench with rain, the flood reason, rotten spoil may expose the field again; The 3rd, may be stolen profit by the money-grubber.This method has been subjected to increasing restriction.

(2), burning method: spoil is placed on handles in the high temperature mode in the specific device and change into ashes.This method: the one, have high input; The 2nd, the operation cost height; The 3rd, disposal ability is limited; The 4th, producing pernicious gas needs to handle again.

(3), high temperature and high pressure method: by HTHP spoil, tissue are become common rubbish, and then further handle.Further handle dual mode is arranged: the one, carry out after crushed being used as fertilizer behind the biofermentation; The 2nd, meat meal tankage and grease are reclaimed in water-oil separating, and waste water discharges through handling back up to standard again.This method: the one, process procedure is many, and waste water can not directly discharge, and needs to handle again.The 2nd, the animal flesh bone meal of dying of illness reclaims as the feed risk too big.Reason (due to edible similar pluck of ruminant and meat meal tankage) owing to state's rabid ox diseases such as America and Europe, Japan, China and developed country have all forbidden the ruminant employing former forage of animal (meat meal tankage) raising, the especially meat meal tankage of epidemic-infected animal at present.

(4), chemical hydrolysis: spoil, tissue are put into the effect of hydrolysis center processor, the most at last the lipid of protein, nucleic acid, all cells and the tissue in pathogenic microorganism and the animal body body be converted into have little peptide, the neutral aseptic aqueous solution and the bone slag of amino acid, sugar, soap.

Summary of the invention

In view of the above problems, main purpose of the present invention is to provide a kind of chemical method of handling spoil.Its cardinal principle is:

Utilize the basic hydrolysis under its suitable high temperature, the lipid of protein, nucleic acid, all cells and tissue in pathogenic microorganism and the animal body body is converted into have little peptide, the neutral aseptic aqueous solution and the bone slag of amino acid, sugar, soap.In this process, alkali itself is consumed by producing salt hydrolysis solution.Unique solid by-product is that the mineral matter of vertebrate bone and tooth constitutes thing.Those solid residues are very soft, are easy to pulverize, and become the calcium phosphor powder.

Its main process is as follows:

1, to pathogenic microorganism

Pathogenic microorganism basic comprising in the epidemic-infected animal body is identical substantially with animal body, and mainly by protein, carbohydrate and nuclear propylhomoserin constitute.In hydrolytic process, can transform into amino acid and sugar.

2, to protein

Protein is the main solid part of zooblast and tissue.The base unit of protein is an amino acid, and amino acid forms peptide chain by dehydrating condensation.Protein is made up of one or more polypeptide chain.The basic hydrolysis process can cause all peptide bond fissions in the protein, and (wherein a part of amino acid destruction is as arginine, asparagine, glutamine and alanine to produce free amino acid; Another part amino acid is by racemic), some few peptide and carbohydrate side chains.

3, to lipid

The lipid that 6-7% is arranged in the animal body approximately.Simple fat is made up of three fatty acid chains, three fatty acid chains and is connected with a glycerol molecule by ester bond.In the basic hydrolysis processing procedure, all ester bonds together with the sterol ester and the phosphatide of emiocytosis thing and cell membrane, produce the sodium salt of aliphatic acid and with salt, i.e. soap.

4, carbohydrate

Carbohydrate in the animal tissue mainly contains sugar, starch and cellulose.Separate in the processing procedure in alkalescence, carbohydrate and starch are dissolved rapidly, and cellulose then can be decomposed through the long period.

5, to the nuclear propylhomoserin

The nuclear propylhomoserin is a linear polymer large-scale, branch branch, is to be lumped together by the phosphodiesterase binding.Separate in the processing procedure in alkalescence, can destroy ribonucleic acid and DNA, form free nucleotides.

6, to the bone class

Inorganic constituents for bone tissue and the tooth (calcium, phosphorus) of animal is sterilized in the process of hydrolysis, becomes the calcium phosphor powder.

The specific embodiment

The present invention relates to a kind of chemical method of handling the epidemic-infected animal corpse, its advantage is:

1, with the metaplasia of animal is a kind of aseptic, neutral, aqueous solution of being suitable for being discharged into the sanitary sewage system

2, sterilization and digestion work are finished in once-through operation, and the volume and weight of refuse is reduced more than 97 percent, destroy cause of disease fully.

3, running cost only is equivalent to the sub-fraction of incinerator

4, environmental protection: not to any harmful substance of airborne release, the solution that is produced is a kind of nutrition for the microorganism of wastewater treatment plant, also is like this for needs alkalescence is offset the microorganism of the acidity that the sanitary sewage biodegradation process produced.

5, eliminate radioactivity tissue, neutralisation toxin fixative, extracellular toxin and other multiple toxin compounds.

Its concrete mechanism is as follows:

1, to pathogenic microorganism

2, to protein

Protein is the main solid part of zooblast and tissue.The base unit of protein is an amino acid, and amino acid forms peptide chain by dehydrating condensation.Protein is made up of one or more polypeptide chain.The basic hydrolysis process can cause all peptide bond fissions in the protein, and (wherein a part of amino acid destruction is as arginine, asparagine, glutamine and alanine for the sodium salt of generation free amino acid and sylvite; Another part amino acid is by racemic), can produce some few peptides (amino acid short chain) in the middle of this process, carbohydrate side chain is released from glycoprotein in addition.Under the situation of the extreme temperature of basic hydrolysis process and extreme concentrated acid, the protein coat of virus is destroyed, and the eunuch of protein virus is interrupted.
