Background technology
At present, in aquaculture, dead livestock and poultry treatment process mainly contains buried, burning, commercial grease refines and processes.Buried meeting pollutes soil and groundwater; Burning cost is high and atmosphere is had to pollution; It is low that grease refines biological safety, easily diffusion propagation in transportation of pathogenic micro-organism, so dead fowl poultry is carried out to compost treatment, the method turning waste into wealth is adopted by increasing breeding enterprise.
It is CN101838166A that State Intellectual Property Office discloses a publication number in 2010.9.22, name is called the patent of invention of " the static compost hazard-free treatment process of animal meat corpse and products thereof ", this patent relates to a kind of static compost hazard-free treatment process of animals and animal product, belongs to field of Environment Protection.It is characterized in that using the nitrogenous source auxiliary materials such as the carbon source auxiliary materials such as hay and animal excrement, with animal meat corpse and products thereof hybrid composting simultaneously.On compost method of construction, according to the weight of animals, adopt single or multiple lift method of construction.After compost builds up, make to pile temperature rise to 55 degree and keep more than 3 days or be increased to 45 degree keeping more than 7 days, making the basic deactivation of disease microorganism.After compost builds up, static treatment, through turning after a period of time, repeatedly until complete compost fermentation, reaches compost maturity utilization.Safety of the present invention, environmental protection, economy, the cheap compost auxiliary material degraded carcase of using the rural areas such as hay, stalk, animal excrement easily to obtain, animal meat corpse and products thereof can access thorough decomposition, and change into useful green organic plant fertilizer, for the application of animal epidemics in breaking out provides a kind of practicable method.
It is CN102391029A that State Intellectual Property Office discloses a publication number in 2012.3.28, name is called the patent of invention of " composting treatment method that dyes avian influenza chicken and products thereof ", this patent discloses a kind of composting treatment method that dyes avian influenza chicken and products thereof, by in pending sample buried foundation windrow, compost fermentation is more than 12 days, in fermenting process, heap temperature 55-60 ℃ continues at least 7 days, humidity 60-70%, pH8.7 ± 0.2.Technical scheme provided by the present invention is utilized the high temperature kill pathogenic bacteria that produces in composting process, weed seed, worm's ovum etc.In addition; the important component part of the plants such as the soil microorganisms of heap in body can degraded cellulose, xylogen; product after conversion can be used as fertilizer; protection of the environment not only; increase soil fertility; increase water retention in soil, can also reduce volume, smell and the pathogenic bacteria of organic materials, realized the recycle of resource.And method of the present invention is with low cost, equipment simple, easy handling.
Above-mentioned two patents adopt manure fermentation, and ight soil, with a large amount of bacteriums, itself is exactly a kind of source of pollution, can cause the secondary pollution of environment in transfer process, and windrow mode and processing parameter etc. all can cause larger pollution, even can produce harm to human body.
Summary of the invention
The present invention is intended to solve the heavy-polluted problem of fermented product in above-mentioned prior art, and the compost method of a kind of dead fowl poultry is provided, and reaches simple to operate, safety, convenience, free of contamination object.
In order to realize foregoing invention object, its concrete technical scheme is as follows:
A compost method for dead fowl poultry, is characterized in that: comprise following processing step:
A, windrow
Organic carbon source material is put into the container bottom of open-top, formed padding layer, then inoculated bacteria; In padding layer, put into dead fowl poultry; On dead fowl poultry, put into organic carbon source material, form tectum, then inoculated bacteria;
B, first stage compost
Controlling temperature in container is 65-75 ℃, and controlling moisture content in material is 50-60%, and controlling material pH value is 6.5-7.5, under these conditions compost 360-480 hour;
C, stirring
After first stage compost finishes, padding layer, dead fowl poultry and tectum are uniformly mixed;
D, subordinate phase compost
The padding layer mixing in step C, dead fowl poultry and tectum are moved to Secondary Fermentation pond, in material, ventilate, fermentation 7-10 days;
After E, oven dry, obtain fertilizer.
The present invention is in steps A, and described organic carbon source material is stalk and sawdust.
The additional proportion of above-mentioned stalk and sawdust is 1:1.
The present invention is in steps A, and described padding layer, dead fowl poultry and the tectum separately volume of shared container equate.
The present invention is in steps A, and the described bacterium inoculating in padding layer and tectum is aerobic bacteria.
The present invention, in step D, described refer in described bottom, Secondary Fermentation pond induction pipe, ventilation 2-3 minute per hour is set to ventilation in material.
The present invention brings useful technique effect:
1, the dead livestock and poultry of compost treatment of the present invention are with respect to burning, the method such as buried, equipment is simple, easy to operate, biological safety is high, environmental pollution is little, and composting production can be used as fertilizer, not only realize harmless treatment but also realized the recycling of waste pollutant, it is a kind of well dead livestock and poultry treatment process, parameter in composting mode of the present invention and composting process is controlled, comprise temperature, time, pH value, the isoparametric control of moisture content, be all on the basis of existing compost method, be optimized improved, can further reduce the pollution of environment and the harm to the mankind.
2, the windrow mode in steps A of the present invention is improved for the shortcoming of prior art, and three layers of windrow adopt upper and lower two-layer carbon source, and centre is dead fowl poultry, can avoid like this introducing other source of pollution in plant, prevents crossed contamination; The process parameter control of first stage compost, for bacterial growth provides favourable condition, is beneficial to bacterial reproduction; The present invention is in steps A, described organic carbon source material is stalk and sawdust, and the additional proportion of stalk and sawdust is 1:1, can keep suitable carbon-nitrogen ratio like this, for microorganism growth provides suitable carbon source, in addition described padding layer, dead fowl poultry and tectum separately the volume of shared container equate also can guarantee enough carbon sources.
